A grease gun holds a cylindrical tube of grease that is 14 in. long and has a radius of 1.5 in. With each squeeze, 15 in3 of gre
almond37 [142]
So first solve for for volume of grease held by tube

volume of cylinder=height times area of base
area of base=circle so
height times pi times radius^2
pi=aprox 3.14

height=14
radius=1.5

14 times 3.14 times 1.5^2=98.91 in^3 of grease

then divide
98.91/15=6.594
you can't squeeze the gun exactly  0.569 times so we round down and get
6
the answer is 6 times

Use the function below to find F(2).<br> F(t) = 2•1/2^3t
navik [9.2K]

Answer:

F(2)= \frac{1}{32}

Step-by-step explanation:

The given function is

F(t) = 2 \cdot \:  \frac{1}{{2}^{3t} }

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

F(2) = 2 \cdot \:  \frac{1}{{2}^{3 \times 2} }

We multiply the exponent in the denominator to get:

F(2) = 2 \cdot \:  \frac{1}{{2}^{6} }

We evaluate to get:

F(2) = 2 \cdot \:  \frac{1}{64}

We now cancel the common factors to get:

F(2) = \frac{1}{32}

Which graph can be used to find the solution(s) to x ^ 2 - 1 = x + 1 ?
NikAS [45]

Step-by-step explanation:

Step 1 - Separate LHS and RHS of the given polynomial.

--- (1)

y = x + 1 --- (2)

Step 2 - Draw the graph of a line (y = x + 1) that passes through the points (-1,0) and (0,1).

Step 3 - Now, draw the graph of the equation (1). The shape of this graph is the upward parabola.

Step 4 - The two graphs intersect each other at (-1,0) and (2,3).

From the above steps, it can be concluded that the correct option is C).
