Answer:

B. y=3/2x+8

Step-by-step explanation:

To find the perpendicular line, you find the reciprocal or the slope, so the reciprocal of this slope is 3/2. B is the only answer with the correct slope

Answer:

B

Step-by-step explanation:

Easiest way to tell is by flipping the slope and changing the sign, so it goes from -2/3 to 3/2. The only answer with that slope is B

31

The expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

An expression that has a value of 31

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

A) 3√25 + 7-5

= 3(5) + 7 - 5

= 15 + 7 - 5

= 17

B) (3√25) +7-5

= (3x5) +7-5

= 15 +7-5

= 17

C) 3√25+ (7-5)

= 3x5 +2

= 17

D) 3(√25 + 7) - 5

= 3(5+7) - 5

= 36 - 5

= 31

Thus, the expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

Step-by-step explanation:

Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t

is measured in seconds. The rate at which the area covered by the oil is changing at time t = 10 is  A'(10).

Given that:

To determine the rate at which the area covered by the oil is changing with time, we need to differentiate  A(t) with respect to time t.

∴

By differentiation:

[tex]\mathbf{\dfrac{dA}{dt} =A'(t)}[/tex]

∴

[tex]\mathbf{\dfrac{dA}{dt} \Big| _{t=10}=A'(t)\Big|_{t=10}}[/tex]

[tex]\mathbf{\dfrac{dA}{dt} =A'(10)}[/tex]

Therefore, we can conclude that the rate at which the area covered by the oil is changing at time t=10 is  A'(10).

Answer:

h = 18( I might be wrong though)

Step-by-step explanation:

If BE and ED are perpendicular, that means this angle is supplementary.

BEF = 3h-12

FED = 2h - 23

BEF + FED = 90

3h-12 + 2h - 23 = 90

5h - 35 = 90

5h = 90

Step-by-step explanation:

Raia’s monthly car payments is $8160.

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that, Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25%

We need to find;

What are Raia’s monthly car payments?

So, SI = PRT / 100

P = Principal amount

r = rate

T = time

So,

SI = 32000 x 4.25 x 6 / 100

= 8160

Hence, Raia’s monthly car payments is $8160.

Answer:

  an infinite number of ways

Step-by-step explanation:

The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.

So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."

__

One way to describe it is this:

The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.

__

* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given,

Jay walks 3 blocks north and then 4 blocks east from his home if he walks straight back home.

We have to use pythagorean theorem in finding distance

As given in the attachment, Let AB= 3

BC=4

AC=x

To find AC we use pythagorean theorem

AC²=AB²+BC²

AC²=3²+4²

AC²=9+16

AC²=25

Take square root on both sides.

AC=5

Hence 5 blocks he walks straight back home how far does Jay walk-in all
