Step-by-step explanation:

an object and its shadow create a right-angled triangle.

2 objects and their shadows create 2 similar right-angled triangles.

that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.

so,

42 × f = 6

f = 6/42 = 1/7

the length of Joel's shadow is then

20 × f = 20 × 1/7 = 2.857142857... ft

2x -1 = - 7

A. 7 - 4 = 3. So, these points are separated by a distance of 3 units.

B. 2 - 1 = 1. So, these points are separated by a distance of 1 unit.

C. 3 - 1 = 2. So, these points are separated by a distance of 2 units.

D. 8 - 4 = 4. So, these points are separated by a distance of 8 units.

So A. is the correct answer.

Answer:

x = 8

Step-by-step explanation:

The two sides equal each other

5x - 13 = x + 19  Subtract x from both sides

5x - x - 13 = x - x + 19

4x - 13 = 19  Add 13 to both sides

4x - 13 + 13 = 19 + 13

4x = 32  Divide both sides by 4

x = 8

Answer:

17² = 8² + (UT)²

289 = 64 + x²

x² = 289-64

x² = 225

x = 15

UT = 15

Answer:

UT = 15

Step-by-step explanation:

17² = 8² + (UT)²

289 = 64 + x²

x² = 289-64

x² = 225

x = 15

UT = 15

Answer:

2 seconds later

Step-by-step explanation:

Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64

The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;

Since y = -16t² + 64

0 =  -16t² + 64

16t² = 64

t² = 64/16

t² = 4

t = ±√4

t = 2 and -2

Time cannot be negative, hence the ball hits the ground 2 seconds later.

Note that the equation used was assumed. Similar solution can be applied for any given equation.

The rectangle with the maximum area, formed by its base on the x-axis and two vertices on the parabola y = 49 - x^2, has dimensions of length 14 units and height 0 units.

To find the dimensions of the rectangle that maximize its area, we need to consider the relationship between the rectangle's dimensions and the parabola.

Let's assume the length of the rectangle is 2x, and the height is y. Since the base of the rectangle lies on the x-axis, the y-coordinate of the two vertices on the parabola will be zero.

Substituting the y-coordinate into the equation of the parabola, we have:

0 = 49 - x^2

Rearranging the equation:

x^2 = 49

Taking the square root of both sides:

x = ±√49

Since we are interested in the positive value of x, we have:

x = 7

Now, substituting this value back into the equation of the parabola, we can find the height:

y = 49 - (7^2)

y = 0

Therefore, the dimensions of the rectangle that maximize its area are:

Length = 2x = 2 * 7 = 14 units

Height = y = 0 units

The rectangle is a degenerate rectangle, which means it has a height of zero. In this case, the maximum area is achieved when the rectangle becomes a line segment on the x-axis with a length of 14 units.

The functions covariance.p and covariance.s return different values because they use different formulas for calculating the covariance.

Covariance is a measure of how two variables are related to each other, and it is used to understand the linear relationship between two variables. The formula for calculating covariance depends on the type of data being analyzed. The covariance.p function calculates population covariance, while covariance.s calculates sample covariance.

The formula for population covariance uses N in the denominator, while the formula for sample covariance uses N-1 in the denominator. This is because the sample covariance formula is an unbiased estimator of the population covariance, and using N-1 instead of N corrects for the bias.

Therefore, the two functions return different values even when using the same data because they are calculating different types of covariance using different formulas.

The value of c is approximately -1.964.To find the value of c in the equation A = 70.5 + 19.5 sin(pi/6t + c), we need to use the given information that the coldest temperature occurs in January (t = 1).

Substituting t = 1 into the equation, we have:

A = 70.5 + 19.5 sin(pi/6 + c)

We know that the coldest temperature occurs in January, which means it is the minimum value of A. For a sine function, the minimum value is -1. Therefore, we can set A = -1 and solve for c.

-1 = 70.5 + 19.5 sin(pi/6 + c)

Rearranging the equation, we have:

19.5 sin(pi/6 + c) = -1 - 70.5

19.5 sin(pi/6 + c) = -71.5

Dividing both sides by 19.5, we get:

sin(pi/6 + c) = -71.5 / 19.5

Using the inverse sine function (arcsin), we can solve for c:

pi/6 + c = arcsin(-71.5 / 19.5)

c = arcsin(-71.5 / 19.5) - pi/6

Using a calculator to evaluate the inverse sine and subtracting pi/6, we find:

c ≈ -1.964

The required population of the bacteria in the culture after 9 hours, to the nearest whole number, is 394 bacteria.

The half-life of the element is defined as the time span in which the element grows or decays half of its whole composition of growth and decay.

Here,
Given an expression that represents the growth of the bacteria,
\(P_t = P_0 (2)^{t/d}\)

From the quesiton put the respective values to determine the population of bacteria in the culture after 9 hours, to the nearest whole number,
\(P_9 = 160 \times 2^{9/8}\\P_9 = 393.9\)

The coordinate of first stop of bus which is halfway through the route. is (9, -9).

What is coordinate?

Using the horizontal and vertical separations from the two reference axes, a coordinate is a pair of numbers that expresses a point's location on a coordinate plane. generally expressed by the x-value and y-value pair (x,y).

We have to find the coordinate of first stop of bus which is halfway through the route.

It means, We have to find the coordinates of the midpoint of line segment which has start point and end point coordinates as A(-10, 10) and B(8, -8).

The formula to get the mid point coordinate of a line segment which start point and end point coordinates as A(x₁, y₁) and B(x₂, y₂) is:

\(M(a,b) = (\frac{x_2 -x_1}{2} , \frac{y_2-y_1}{2} )\)

putting the value from question:

\(M(a,b) = (\frac{8 -(-10)}{2} , \frac{-8-10}{2} )\)

M(a, b) = (9, -9)

Therefore the coordinate of the midpoint is (9, -9)

From the provided equations, the equation which has no solution is 3 4 x less-than-or-equal-to 2 +4x. Option 2 is correct.

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

From the given equations, the equation which has no solution has to be found out. When the value, does not equate for the expression, then the expression has no solution.

The first equation given in the problem is,

\(6 (x +2) > x-3\)

Solve it further,

\(6 x +12 > x-3\\6x-x > -3-12\\5x > -15\\x > -3\)

The second equation given in the problem is,

\(3+ 4x \leq 2 (1 +2x)\)

Solve it further,

\(3+ 4x \leq 2 +4x\\4x- 4x \leq 2-3\\0\leq-1\)

The value of 0 is greater than the number -1. Thus, this inequality has no solution.

The option 3 and 4 has a solution. Hence, from the provided equations, the equation which has no solution is 3 4 x less-than-or-equal-to 2 +4x. Option 2 is correct.
