Consider the graph of the equation y = 5. Which statements are true? Check all that apply.

levacccp [35]

Answer:

The graph of y=5 is a horizontal line. The point (-4, 5) lies on the lines.

Step-by-step explanation:

This is horizontal because 5 on the y axis is always going to stay the same. For any x value, the y value is 5. Therefore, (-4, 5) is part of that line.

Bethany has $3.10 in nickels and dimes. She has a total of 44 coins. What is the value of the nickels Bethany has?

lesantik [10]

0.05n + 0.1d = 3.10
n + d = 44

d = 44 - n

Substituting to the first equation:

0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26

Obtaining the value of nickels:
26 * 0.05 = 1.3

Therefore, the value of nickels that Bethany has is $1.30

Please help, nobody is helping I need to find surface area

Reil [10]

Answer:

A) 147.6 sq m

Step-by-step explanation:

Separate the pyramided out into 4 triangles and add those

3 of them (sides) will be the same

$A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20$

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.

The area of all 3 sides together is 40*3 = 120 sq m

For your base, your height will be 6.9 and your base is 4

A = 13.8 sq m

multiply by 2 again for the entire base

A=27.6 sq m

Now add both

120 + 27.6

The height of a trapezoid is 6 in. and it’s area is 72 in to the 2nd power. One base of the trapezoid is 6 inches longer than th

Vitek1552 [10]

Given:

The height of the given trapezoid = 6 in

The area of the trapezoid = 72 in²

Also given, one base of the trapezoid is 6 inches longer than the other base

To find the lengths of the bases.

Formula

The area of the trapezoid is

$A=\frac{1}{2} (b_{1} +b_{2} )h$

where, h be the height of the trapezoid

$b_{1}$ be the shorter base

$b_{2}$ be the longer base

As per the given problem,

$b_{2}=b_{1} +6$

Now,

Putting, A=72, $b_{2}=b_{1}+6$ and h=6 we get,

$\frac{1}{2} (b_{1} +b_{1}+6)(6) = 72$

or, $b_{1}+b_{1}+6 = \frac{(72)(2)}{6}$

or, $2b_{1}+6 = 24$

or, $2b_{1}=24-6$

or, $b_{1}= \frac{18}{2}$

or, $b_{1}=9$

So,

The shorter base is 9 in and the other base is = (6+9) = 15 in

Hence,

One base is 9 inches for one of the bases and 15 inches for the other base.

Find the function value of cos^2 (7pi/8)

Kamila [148]

$\cos^2\dfrac{7\pi}8=\dfrac12\left(1+\cos\dfrac{7\pi}4\right)$
$=\dfrac12+\dfrac12\cos\left(-\dfrac\pi4\right)$
$=\dfrac12+\dfrac12\cos\dfrac\pi4$
$=\dfrac12+\dfrac1{2\sqrt2}$
$=\dfrac{\sqrt2+1}{2\sqrt2}$
$=\dfrac{2+\sqrt2}4$
