∆ABC has side lengths of 10 units, 20 units, and 24 units. ∆XYZ is similar to ∆ABC, and the length of its longest side is 60 uni

ts. The perimeter of ∆XYZ is units. If the height of ∆ABC, with respect to its longest side being the base, is 8 units, the area of ∆XYZ is square units.

Answer: Perimeter = 135 units      Area = 1200 Square units

Step-by-step explanation: I think you want the perimeter and area of XYZ so that's what I will answer for.

First, we are given that ABC and XYZ are proportional and that their longest sides are 24 units and 60 units respectively.

Using this, we can say XYZ = ABC * 5/2 (60/24 = 5/2)

Therefore, the other two sides of XYZ are 50 and 25.

We can get the perimeter using 60 + 50 + 25, that equals 135 units

Next, since the height of ABC was 8 units with 24 units being its base, it's likely safe to say the height = 1/3 base

We will apply with to triangle XYZ, height = 1/3 * 60 = 20

20 units * 60 units = 1200 square units

O find the minimum value of the quadratic expression −4x2+8x−25,
fredd [130]

Answer:

Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x

Step-by-step explanation:

we have

-4x^{2}+8x-25

This is a vertical parabola open downward

The vertex is a maximum

Find the vertex

step 1

Factor the leading coefficient -4

-4(x^{2}-2x)-25

step 2

Complete the square

-4(x^{2}-2x+1-1)-25

step 3

-4(x^{2}-2x+1)-25+4

-4(x^{2}-2x+1)-21

step 4

Rewrite as perfect squares

-4(x-1)^{2}-21

the vertex is the point (1,-21)

so

The maximum value of the quadratic equation is (1,-21)

therefore

Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x

At the rate of $2.00 per square foot the cost of painting the rectangular board with a semicircular top shown in the figure is $
Elenna [48]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
<span> 
it consists of a rectangle, dimensions  L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2

</span>then, you have one half of the area of the circle that has diameter  R = 3ft - radius will be r = 1.5ft the area of that half will be:

Ac = r^2 \pi/ 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2 
= 7.065 ft^2/ 2 
= 3.5325ft^2

A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2

<span>At the rate of $2 per square foot, the cost will be: 
$ 15.5325*2 = 31.07 </span>

Find the inverse of the function. y = 2x2 –4
Alex73 [517]

Answer:

The inverse function is y=\sqrt{\frac{x+4}{2}}


Step-by-step explanation:

The given function is y=2x^2-4.


This function is only invertible on the interval, x\ge 0.


To find the inverse on this interval, we interchange x and y.

x=2y^2-4


We now make y the subject to get,


x+4=2y^2


\Rightarrow \frac{x+4}{2}=y^2


\Rightarrow \pm \sqrt{\frac{x+4}{2}}=y


But the given interval is x\geq 0, This implies that, y\geq 0.


y=\sqrt{\frac{x+4}{2}}
