Find the volume of a pyramid with a square base, where the perimeter of the base is 7.3\text{ ft}7.3 ft and the height of the py

Cloud [144]

Answer:

$V=6.66\ ft^3$

Step-by-step explanation:

The perimeter of the square base of a pyramid = 7.3 ft

The height of the pyramid, h = 6ft

The perimeter of a square is given by :

P = 4s, s is the side of square

7.3 = 4s

s = 1.825 ft

The volume of a pyramid is given by :

$V=\dfrac{lbh}{3}$

Here, l = b = 1.825 ft

So,

$V=\dfrac{1.825\times 1.825\times 6}{3}\\\\V=6.66\ ft^3$

So, the volume of the pyramid is equal to $6.66\ ft^3$ .

Two more than-4 times a number is greater than or equal to 26. Then solve.

Alexandra [31]

So with word problems just make sure to read it correctly. So it’s -4 times a number, which I will name x, plus 2.
Greater than means the crocodile will eat it. So facing
-4x+2 >= 26
Now isolate the x, or number
-4x=24
Divide by -4
x= -6

What is the equation of the line that passes through the point (-2,-1) and has a slope of 5/2

Darya [45]

Answer:

y = (5/2)x + 4

Step-by-step explanation:

We'll look for an equation in the format y = mx + b, where mn is the slope and b the y-intercept (the value of y when x = 0).

y = mx + b

m is (5/2)

y = (5/2)x + b

We need a value of b that will force the line through point (-2,-1). Enter the point (-2,-1) in the equation and solve for b:

y = (5/2)x + b

-1 = (5/2)(-2) + b

-1 = -5 + b

b = 4

<u>The equation is y = (5/2)x + 4</u>

If G(x) = 3x + 1, then G^-1(1) is

NISA [10]

One way in which to do this problem is to find the inverse function of G(x) first. Another, faster, method is to look at G(x) = 3x + 1. Find the x value for which y = 1:

1 = 3x + 1. Then x must equal 0. If (0, 1) satisfies G(x) = 3x + 1, then (1, 0) satisfies the inverse function of G(x) = 3x + 1.

Thus, the value of the inverse function with input 1 is 0.

Step 1: Replace "G(x)" with y.

Step 2: Solve the resulting equation for x.

Step 3: Replace x with y and y with x.

-1

Step 4: Replace this "y" with G (x).

Now replace "x" with "1".
