what is x? -8=-(x+4)

Answer:

20 years

Step-by-step explanation:

We start by writing an exponential equation;

FV = PV( 1 + r)^t

FV is the future value = 1,000,000

PV is present value = 372,000

r is rate = 5% = 5/100 = 0.05

t is time which we are looking for

1,000,000 = 372,000(1 + 0.05)^t

1.05^t = 1,000,000/372,000

1.05^t = 2.688

t ln 1.05 = ln 2.688

t = ln 2.688/ln 1.05

t = 20 years

Answer: The Range is 5,4,8

Step-by-step explanation:

Answer: The range is [4,8]

Step-by-step explanation:

What you want to look for is the smallest and largest y values, the smallest value is 4 and the largest is 8.

When answering a problem like this you want to put the smaller value first, so in this case, we put 4 first

So the equation for range would be something like 4 \(\leq\) y \(\geq\)  8

We use [ , ] because the brackets need that the said value is included in the data set.

Therefore we use the range equation to create the answer

The final horse power when the driving a car in Denver that's rated at 300 horsepower is 252.48  , the correct option is (c) .

In the question ,

it is given that ,

the power of the car is rated as = 300 horse power

we know that Rule of thumb states that for every 1000 feet the horsepower reduces by 3 percent .

that means ,

for percent of power loss at 1000 feet = 3%

So , the percent loss of power at 5280 feet is  = (3/1000)×5280

= 0.003 × 5280

= 15.84 % .

So , 15.84% of 300 is = 47.52

So , the power loss is 47.52 .

the final horse power is = 300 - 47.52 = 252.48

Therefore , The final horsepower is 252.48  .

When light strikes a leaf, it can be absorbed by, reflected from or transmitted through the leaf. Plants appear green because they reflect and transmit slightly more green light than they do blue or red light. Chlorophyll also absorbs green light poorly.

Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen  and chemical energy stored in glucose (a sugar). Then, herbivores get this energy from eating plants, whereas predators get it from consuming other herbivores.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy inside the glucose molecules, the plant releases the oxygen back into the atmosphe.

\(r=d\div 2 = 2.3 \div 2 = 1.15\\\\\dfrac{1}{3}\pi r^2 h = \dfrac{1}{3}\pi (1.15)^2 (7.8) \approx 10.802\)

The angle is in 4th quadrant and the value of \(sin\theta\) is -(4/5).

One of the most significant areas of mathematics, trigonometry has a wide range of applications. The study of the connection between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry." Therefore, employing trigonometric formulae, functions, or trigonometric identities can be helpful in determining the missing or unknown angles or sides of a right triangle. Angles in trigonometry can be expressed as either degrees or radians.

There are two other sub-branch classifications for trigonometry. The two varieties of trigonometry are as follows:

Everything is normal in Quadrant I, and Sine, Cosine, and Tangent are all positive.

However, the x direction is negative and the cosine and tangent become negative in Quadrant II.

Sine and cosine have negative values in Quadrant III.

Sine and tangent are negative in Quadrant IV.

since,

\(cos\theta = 3/5 (+ve)\\\ sin\theta\ is\ ( -ve)\).

So the angle is in 4th Quadrant.

we know,

\(sin^{2}\theta + cos^{2}\theta = 1\)

⇒ \(sin^{2}\theta = 1 - (\frac{3}{5}) ^{2}\)

⇒\(sin^{2}\theta = 1 - \frac{9}{25} = \frac{16}{25}\)

⇒ \(sin\theta = -\frac{4}{5}\)     (since The angle is in 4th Quadrant)

The equation of the line with a slope of 3/4 passing through the point (2,1) is y = (3/4)x - 1/2.

In mathematics, slope refers to the measure of steepness or incline of a line, usually denoted by the letter m.It is the ratio of the vertical change in position of two points on a line to their horizontal change.

The equation of a line with a slope of 3/4 passing through the point (2,1) can be found using the point-slope form of the equation of a line:

y - y₁ = m(x - x₁)

where m is the slope of the line, and (x₁,y₁) are the coordinates of the given point on the line.

Substituting the given values, we get:

y - 1 = (3/4)(x - 2)

Multiplying both sides by 4 to eliminate the fraction, we get:

4y - 4 = 3(x - 2)

Expanding the right-hand side, we get:

4y - 4 = 3x - 6

Adding 4 to both sides, we get:

4y = 3x - 2

Dividing both sides by 4, we get the final equation in slope-intercept form:

y = (3/4)x - 1/2

Therefore, the equation of the line with a slope of 3/4 passing through the point (2,1) is y = (3/4)x - 1/2.

Determination, also known as R-squared. The coefficient of determination, denoted by \(R^{2}\), is a statistical measure that ranges from 0 to 1 and indicates how well the regression equation fits the data.

An \(R^{2}\) value of 0 indicates that the regression equation does not explain any of the variation in the response variable, while an \(R^{2}\) value of 1 indicates that the regression equation perfectly explains all of the variation in the response variable. In general, a higher \(R^{2}\) value indicates a better fit of the regression equation to the data.

The formula for calculating \(R^{2}\) is:

\(R^{2} =  \frac{SSR}{SSTO}\)

where SSR is the sum of squares due to regression (also known as explained sum of squares), and SSTO is the total sum of squares (also known as the total variation).

The coefficient of determination is an important tool in regression analysis because it helps to determine the strength and direction of the relationship between the independent and dependent variables.

To find the maximum rate of change of the function \(\(f(x, y) = \sin(xy)\)\) at the point (9, 0) and the direction in which it occurs, we can calculate the gradient vector and evaluate it at the given point.

The gradient vector of \(\(f\)\) is given by:

\(\(\nabla f(x, y) = \left(\frac{\partial f}{\partial x}, \frac{\partial f}{\partial y}\right)\)\)

Let's calculate the partial derivatives:

\(\(\frac{\partial f}{\partial x} = y\cos(xy)\)\)

\(\(\frac{\partial f}{\partial y} = x\cos(xy)\)\)

Now, we can evaluate the gradient vector at the point (9, 0):

\(\(\nabla f(9, 0) = \left(0\cos(0\cdot 9), 9\cos(9\cdot 0)\right) = \left(0, 9\right)\)\)

The magnitude of the gradient vector gives us the maximum rate of change of the function at the point (9, 0). The magnitude of \(\(\nabla f(9, 0)\)\) is:

\(\(|\nabla f(9, 0)| = \sqrt{0^2 + 9^2} = \sqrt{81} = 9\)\)

So, the maximum rate of change of \(\(f\)\) at the point (9, 0) is 9.

To determine the direction in which this maximum rate of change occurs, we normalize the gradient vector by dividing it by its magnitude:

\(\(\frac{\nabla f(9, 0)}{|\nabla f(9, 0)|} = \frac{(0, 9)}{9} = (0, 1)\)\)

Therefore, the maximum rate of change of \(\(f\)\) at the point (9, 0) occurs in the direction of the vector (0, 1), which is the positive y-direction.

In conclusion the size of\(\( BE \) will be \( 4 \times 5 \).\)

To determine the size and number of entries of the matrix \( BE \), we need to consider the dimensions of the matrices \( B \) and \( E \) and perform matrix multiplication.

Given:

\(\( B \)\) is a\(\( 4 \times 4 \)\)matrix,

\(\( E \)\)is a\(\( 4 \times 5 \)\)matrix.

In matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix for the multiplication to be defined.

Since\(\( B \)\) has 4 columns and \(\( E \)\) has 4 rows, we can perform the matrix multiplication\(\( BE \).\)

The resulting matrix will have the number of rows from the first matrix (which is\(\( B \))\) and the number of columns from the second matrix (which is \\(( E \)).\)

Therefore, the size of\(\( BE \) will be \( 4 \times 5 \).\)

The number of entries in a matrix is determined by multiplying the number of rows by the number of columns. In this case,\(\( BE \)\) has\(\( 4 \times 5 = 20 \)\) entries.

Inverse of a Function.

To find the inverse of the function f(x) = √(x+7), we need to interchange the roles of x and y and solve for y.

Let y = f(x) = √(x+7)

To find the inverse, we need to solve for x in terms of y.

Step 1: Square both sides of the equation to eliminate the square root:

y^2 = x + 7

Step 2: Solve for x:

x = y^2 - 7

So the inverse of the function f(x) is:

f^(-1)(y) = y^2 - 7

We can also express the inverse in terms of x:

f^(-1)(x) = x^2 - 7

Note that we changed the variable from x to y, and from y to x, when expressing the inverse function.

The statement "a. The slope is negative" is true about the slope of the least squares regression line when the correlation coefficient is negative.

When the correlation coefficient is negative, it indicates an inverse relationship between the two variables. In a linear regression, the slope of the line represents the direction and magnitude of the relationship between the independent and dependent variables. A negative correlation coefficient indicates that as the independent variable increases, the dependent variable decreases. Therefore, the slope of the least squares regression line will also be negative.

The slope of the regression line is calculated using the formula: slope = correlation coefficient * (standard deviation of y / standard deviation of x). Since the correlation coefficient is negative and the standard deviation of x and y are positive values, multiplying a negative correlation coefficient by positive standard deviations will result in a negative slope. Hence, option "a. The slope is negative" is the correct statement.
