Answer:

6i[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] = [tex]\sqrt{ab}[/tex] and [tex]\sqrt{-1}[/tex] = i

Given

[tex]\sqrt{-72}[/tex]

= [tex]\sqrt{36(2)(-1)}[/tex]

= [tex]\sqrt{36}[/tex] × [tex]\sqrt{2}[/tex] × [tex]\sqrt{-1}[/tex]

= 6[tex]\sqrt{2}[/tex] × i

= 6i[tex]\sqrt{2}[/tex]

Answer:

The radius of the hole is 0.42 feet

Step-by-step explanation:

Let us revise the rule of the volume of a cylinder

→ V = πr²h, where

→ V is the volume of the cylinder in a cubic unit

→ r is the radius of the base of the cylinder

→ h is the height of the cylinder

Let us solve our question

→ The volume of the cylinder is 3800 cubic feet

→ The height of the cylinder is 1.3 miles

Very Important Note: dimensions must have the same unit

→ Change the mile to feet

→ There are 5280 feet in 1 mile

→ Multiply 1.3 miles by 5280 to change it to feet

→ The height = 1.3 × 5280 = 6864 feet

Let us substitute the values of V and h in the rule above

∵ V = πr²h

∵ V = 3800 ft³

∵ h = 6864 ft

∴ 3800 = πr²(6864)

→ Divide both sides by 6864π to find r²

∴ r² = 0.1762205081

→ take √  for both sides to find r

∴ r = 0.4197862648

→ Round it to the nearest hundredth

∴ r = 0.42 ft

The radius of the hole is 0.42 feet

Answer:

(-1, 0), (2, 0), (3, 0)

Step-by-step explanation:

x-intercept of a line is defined by a point where y = 0.

So the point in the form of (x, 0) will be the x-intercept of the given continuous function.

From the table attached,

For x = -1, f(-1) = 0

For x = 2, f(2) = 0

For x = 3, f(3) = 0

Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the continuous function f(x).

[tex]4m+15=5m-10\\15=m-10\\25=m[/tex]

Therefore the answer is D.

Answer:

Step-by-step explanation:

5m - 10 = 4m + 15

m - 10 = 15

m = 25

Answer: Maximum area = 200m

Dimensions:

Length = 10m

Width = 20m

Such that there is only one side of 20m fenced because the other side of 20m is against the rock wall.

Step-by-step explanation:

We have the next problem.

Suppose that the vegetable area is a rectangle of length L and width W.

Such that the width side coincides with the rock wall, then we have that:

The perimeter is:

P = 2*L + 2*W

But because one of the width sides coincides with the wall, the amount of fence needed will be:

P = 2*L + W = 40m

And the area can be written as:

A = W*L

We want to find the maximum area that we can have.

First, write our two equations:

40m = 2*L + W

A = W*L

First we must isolate one of the variables in the first equation, and replace it into the second equation:

40m - 2*L = W.

then:

A = (40m - 2*L)*L = 40m*L - 2*L^2

We can write this as a quadratic equation:

A(L) = -2*L^2 + 40m*L

Now, notice that it has a leading coefficient negative, then the maximum of the area function will be at the vertex of the quadratic equation.

For a quadratic equation:

f(x) = a*x^2 + b*x + c

The vertex is at:

x = -b/2a

and the point is (-b/2a, f(-b/2a))

In this case we have:

b = 40m

a = -2

Then:

we must evaluate the area function in:

L = -40m/(-2*2) = 10m

A(L) = -2*L^2 + 40m*L

A(10m) = -2*100m^2 + 400m = 200m

Now we can find the width using one of the above equations:

W = 40m - 2*L = 40m - 2*10m = 20m

Then the dimensions that the farmer should use are:

Two sides of length 10m, and one side of length 20m

B. Their is no error. This is a conclusion.

Step-by-step explanation I got it right on khan

Helena didn't make any error in her conclusion as the transformation is illustrated accurately.

From the information given, it was stated that Helena was curious if the quadrilaterals were congruent.

In this case, it is not possible to map the quadrilaterals onto each other using a sequence of rigid transformations, so the quadrilaterals are not congruent.

Therefore, no error is made.

Answer:

y=-1/2x-3

Step-by-step explanation:

Answer:

y = -1/2x -3

Step-by-step explanation:

so I got the slope of these two points: (-8,1) and (-6,0) which is:

y₂ - y₁  / x₂ - x₁ = (0-1)/(-6+8) = -1/2

then from the graph it is visible that the y-intercept is -3

so with both of this information:

y = -1/2x - 3

Answer: C

Step-by-step explanation:

The Wilsons' monthly mortgage payment will be approximately $9,485.16.

To calculate the monthly payments for the Wilsons' mortgage, we need to follow these steps:

Convert the annual interest rate to a monthly interest rate using the formula APR(P) = P + 0.02.

Plug the monthly interest rate into the formula m(r) = 128,000 * (r / (1 - (1 + r)⁽⁻³⁶⁰⁾)).

Let's perform the calculations:

Step 1: Convert the annual interest rate to a monthly interest rate

Let's assume the prime interest rate (P) published by the Federal Reserve is 4.5% (0.045 as a decimal).

APR(P) = P + 0.02

APR(0.045) = 0.045 + 0.02

APR(0.045) = 0.065 (monthly interest rate as a decimal)

Step 2: Calculate the monthly payments (m(r)) for a loan of $128,000 with the monthly interest rate (r) obtained from Step 1.

m(r) = 128,000 * (r / (1 - (1 + r)⁽⁻³⁶⁰⁾))

m(0.065) = 128,000 * (0.065 / (1 - (1 + 0.065)⁽⁻³⁶⁰⁾))

Now, let's calculate the monthly payments (m(r)):

m(0.065) = 128,000 * (0.065 / (1 - (1 + 0.065)⁽⁻³⁶⁰⁾))

m(0.065) = 128,000 * (0.065 / (1 - (1.065)⁽⁻³⁶⁰⁾))

m(0.065) = 128,000 * (0.065 / (1 - 0.124823)) (Approximately, (1.065)⁽⁻³⁶⁰⁾ ≈ 0.124823)

m(0.065) = 128,000 * (0.065 / 0.875177)

m(0.065) = 128,000 * 0.074285 (Approximately, 0.065 / 0.875177 ≈ 0.074285)

m(0.065) = 9,485.16

The Wilsons' monthly mortgage payment will be approximately $9,485.16.
