Can someone help me asap!! am timed right now​
Aneli [31]

Answer:

Step-by-step explanation:

Find the value of the left hand side (LHS)

LHS = 1/4 // 5/6

LHS = 1/4 * 6/5

LHS = 6/20

LHS = 3/10

Now what will make 3/10 on the right?

B:  1/4  * 6/5 = 6/20 = 3/10

a = 4

b = 6

c = 5

A right pyramid with a square base has a base edge length of 24 feet and a slant height of 20 feet.
4vir4ik [10]

Answer:

10.583

Step-by-step explanation:

If the height = h

Distance between the slant edge to center is 24 Cos 45

Therefore

h^{2}  = 20^{2}  - (24 Cos 45)^{2}

h = \sqrt{400-288} = 10.583

Estimate L4 and R4 over [0,7] for the function f(x) = 6x^2
jasenka [17]

The value of  L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and  2[2√2 + 2√4 + 2√6 + 2√8] respectively.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that the function is,

I'm assuming that you mean the left and right Riemann sums with four equal subintervals when you refer to L4 and R4.

If so, then Δx = (8-0)/4 = 2, and f(x) = 2√x.

L4 = f(0)Δx + f(2)Δx + f(4)Δx + f(6)Δx

L4 =2[2√0 + 2√2 + 2√4 + 2√6]

R4 = 2[2√2 + 2√4 + 2√6 + 2√8]

Thus, the value of  L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and  2[2√2 + 2√4 + 2√6 + 2√8] respectively.

Let f(x) =-2x-7 and g(x)=-4x+3 find (f•g)(-5)
Ierofanga [76]
F(-5) x g(-5)

f(-5) = -2(-5) - 7
f(-5) = 10 - 7
f(-5) = 3

g(-5) = -4(-5) + 3
g(-5) = 20 + 3
g(-5) = 23

f(-5) x g(-5) = 3 x 23 = 69

Your answer is 69
