Step-by-step explanation:

3(5+7)-5

3*12-5

36-5

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.

Answer:

y = -3x - 11

Step-by-step explanation:

Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.

Point-slope formula: y - y = m(x - x)

Plug in the slope and point

y - (-5) = -3(x - (-2))

Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.

y + 5 = -3x - 6

Subtract the 5 from both sides

y = -3x - 11

The equation of the line is y = -3x - 11

Usually the one with the more vertical line would be steeper.

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.

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:

he walked 7 block's

Jay walks 3 blocks north and then 4 blocks east from his home if he walks straight back home, 5 blocks  does Jay walk-in all

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

Answer:

  G)  $48,357.57

Step-by-step explanation:

The future value formula can be used to find the account value:

  FV = P(1 +r)^t

where P is invested at annual rate r for t years.

  FV = $50,000(1.07^10) ≈ $98,357.57

The amount of interest earned is the difference between this value and the value of the initial investment:

  interest = $98,357.57 -50,000 = $48,357.57

Hank earned $48,357.57 in interest after 10 years.

_____

At 7% interest, the "rule of 72" tells you the doubling time of the account is about 72/7 = 10.3 years. That is the account value will be not quite double the original investment after 10 years. So, the amount of interest earned is only slightly less than $50,000. If the account earned simple interest, the interest earned would be $35,000. Only one answer choice is more than $35,000 and less than $50,000.

-2-(-4)-2

We can break down the problem first. The beginning of the problem is...

-2-(-4)

Two negatives make a positive. An equivalent way to say this is

-2+4

-2+4=2

Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!

2-2=0

The answer to this is 0!

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

h = 18 degrees
