Answer:

a = 7

Step-by-step explanation:

Expand the brackets

Rearrange by collecting the like terms

17 - 10 = 6a - 5a

7 = a

Answer: y = 17x + 114

Step-by-step explanation:

The equation for the slope-intercept form is y = mx + b.

Arrange the equation so that it resembles y = mx + b.

You will do this by multiplying and subtracting so y is on the left side of the equation and mx + b is on the right side of the equation.

y + 5 = 17(x + 7)

y + 5 = 17x + 119

y + 5 - 5 = 17x + 119 - 5

y = 17x + 114

Answer:

Y = 17x + 114

Step-by-step explanation:

1. Y + 5 = 17 (x+7)

2. Y + 5 = 17x + 119   [Multiply the numbers in parenthesis by 17.]

3. Y = 17x + 114.     [To keep the balance and move the 5 over, subtract it from 119.]

Equation of Line K:

The slope intercept form of a line is y = mx + b.

Equation of Line "l":

Line "l" and Line K are parallel. Line "l" will have the same slope.

It will be of the form:

It passes through the point (-2, 2/3). We plug the coordinates of "x" and "y" into the slope intercept form and find b:

Answer:

In isosceles triangle two sides are equal . Let the length be x .hence perimeter can be given as x + x + 6 . Therefore 2x + 6 = 16 . And 2x = 10 .and hence x =5 . So the length of each side is 5 cm

Answer:

Number of cubes = 8 large and 32 small, or 40 total

Step-by-step explanation:

each layer = 2 large and 8 small cuboids.

each layer = 128 cm³

512/128 = 4 layers

so:

4 x 2 = 8 large cuboids

4 x 8 = 32 small cuboids

Answer:

y = 30

x = 60

Step-by-step explanation:

4y and 2y are consecutive angles, which means they are equal to 180° when added together

that is the same with x and (5x - 180)

to solve, you set the equations to 180

solving:

4y + 2y = 180

6y = 180

y = 30

x + 5x - 180 = 180

6x = 360

x = 60

Using translation concepts, a stretch of a decay exponential function is given by:

\(f(x) = 5\left(\frac{1}{5}\right)^x\)

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

An exponential decay function is given by:

\(y = ab^x\)

In which |b| < 1.

A stretch means that the function is multiplied by a factor with absolute value greater than 1, hence the function would be given by:

\(f(x) = 5\left(\frac{1}{5}\right)^x\)

Choice D, the cube

Step-by-step explanation:

Sarah's charges per hour for working during the week will be $9.5.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Sarah is a nanny who bills clients at various prices depending on whether she is working during the week or on the weekend. She worked 45 hours in a single week for a salary of $902.50, of which 5 hours were on the weekend. She worked 50 hours the next week, 10 of which were on the weekend, and made 1045 dollars.

Let x be the charge per working hour and y be the number of charges per hour during the weekend. Then the equation will be

45x + 5y = 902.5           ...1

50x + 10y = 1045

25x + 5y = 522.5          ...2

Subtract equation 2 from equation 1, then we have

45x - 25x = 902.5 - 522.5

20x = 380

x = 19

And the value of y will be

25 (19) + 5y = 522.5

475 + 5y = 522.5

5y = 47.5

y = 9.5

Sarah's charges per hour for working during the week will be $9.5.

Step-by-step explanation: 2.2 is less than 2.25.

The Whole numbers in mathematics are represented in the form of {0 , 1 , 2 , 3 , 4 , ... } .

The Whole Numbers are defined as a set of positive integers, including zero, which do not have a fractional or decimal component.  

The set of whole numbers is denoted by the symbol "W", and it can be expressed as : W = {0, 1, 2, 3, 4, 5, 6, ...}

In other words, the set of whole numbers is the set that starts with 0 and includes all the positive integers which can be obtained by repeatedly adding 1 to the previous number .

If f(x) = sin(x), then the Mean Value Theorem guarantees that somewhere between pi/6 and pi/2, f′(x) is equal to C) 3/2pi

According to the mean value theorem, there must be at least one point

(c, f(c)) on the curve where the tangent is parallel to the secant going through the two supplied points for every function f(x) whose graph goes through the given points (a, f(a)), and (b, f(b)).

We know, f'(c) = [f(b) - f(a)]/(b - a).

Therefore, f'(c) = [sin(π/2) - sin(π/6)]/(π/2 - π/6).

f'(c) = [1 - 1/2]/2π.

f'(c) = (1/2)/(2π/6).

Given:

Length of escalator = 26 ft

Angle of depression = 41 degrees

To find:

The horizontal distance x the escalator covers to the nearest tenth of a foot.

Solution:

In a right angle triangle,

\(\cos \theta=\dfrac{Base}{Hypotenuse}\)

Using this formula for the given triangle, we get

\(\cos 41^\circ=\dfrac{x}{26}\)

\(26\cos 41^\circ=x\)

\(26(0.7547)=x\)

\(19.6222=x\)

Round the value to the nearest tenth.

\(x\approx 19.6\)

Therefore, the escalator covers 19.6 ft horizontally.

"From a table of integrals, we know that for \(\(a \neq 0\)\) and \(\(b \neq 0\):\)

\(\[\int \cos(at) \, dt = \frac{1}{a} \cdot \cos(at) + \frac{1}{b} \cdot \sin(bt) + C\]\)

and

\(\[\int e^a t \cos(bt) \, dt = \frac{e^{at}}{a} \cdot \cos(bt) + \frac{b}{a^2 + b^2} \cdot \sin(bt) + C\]\)

Use this antiderivative to compute the following improper integral:

\(\[\int_{-\infty}^{0} \cos(3t) \, dt = \lim_{{T \to \infty}} \int_{0}^{T} e^t \cos(3t) \, e^{-st} \, dt = \lim_{{T \to \infty}} \text{ if } s \neq 1, \, \text{ or } \lim_{{T \to \infty}} \text{ if } s = 1.\]\)

The value of the expression is -27.

What is an expression?

In mathematics, an expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or a mathematical relationship between quantities. Expressions can be simple or complex, and they can include variables, constants, functions, and other mathematical objects.

First, we can simplify the expression inside the parentheses:

-(-4)(-6) - 3/5 (10+15) = 24 - 3/5 (25)

Next, we can simplify the fraction:

24 - 3/5 (25) = 24 - 15 = 9

So the expression simplifies to:

-9 ÷ 1/3

-9 x 3/1 = -27

Y = 7(1) + 19

y = 7 + 19

y = 26

You have to remember that there are 19 gallons already in the tank and that 1 minute has passed, which means 7 gallons have been added. Thus there are 26 gallons in the water tank.
