Answer:
The correct options are A and C.
Step-by-step explanation:
The given functions are


We have to find to solution for the equation


The solution of the above equation is the intersection of F(x) and G(x).
From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).
The x-coordinates of these points are the solutions of the given equation.
Therefore the solution of given equation are 0 and 2.
Therefore option A and C are correct.
The equation is L = 34 – 0.5d for the water level, L, after d days
<h3><u>Solution:
</u></h3>
Given that , Suppose that the water level of a river is 34 feet
And that it is receding at a rate of 0.5 foot per day.
We have to write an equation for the water level, L, after d days
The equation can be framed for water level after d days which is found by calculating difference between initial level and receding level of water per day
Now , we know that,
<em>water level after d days = initial level – receded level of water.
</em>
L = 34 feet – number of days spent x rate of receding level per day.
L = 34 feet – d days x 0.5 foot
L = 34 – 0.5d
Hence, the equation is L = 34 – 0.5d
Answer:
1. 55.271 inches/lb
2. 3.075 inches/lb
3. The denser one is the pine, so it would be heavier.
Step-by-step explanation:
1. density of the pine log (which is a cylinder)
We need the weight/mass and the volume.
V(cylinder) = πr^2 * height
= πr^2 = π(5^2) = 25π = 78.54
= 78.54 * 30 = <u>2356 cubic inches</u>
The weight is 42.63.
Density = mass/volume = 2356/42.63 = <u>55.271 inches/lb</u>
2. density of the oak board (which is a rectangular prism)
We need the weight/mass and the volume.
V(prism) = l*w*h
= 5.5*1.5*3 = <u>24.75 cubic inches</u>
The weight is 8.05.
Density = mass/volume = 24.75/8.05 = <u>3.075 inches/lb</u>

3. Picture a box made out of stone and a box made out of cardboard. Same dimensions, but the stone one would be way heavier because stone is denser.
Answer:
he earned 14 dollars
Step-by-step explanation:
if you are looking for how much did he earn you take the number that they started with and subtract it from what they have after so the equation is $21-$7 and thats how much he eaened
