What is the answer in the picture below i need help
slega [8]
Heyy this is a super easy problem, and I’m here to help!
Based off our problem here we have a trapezoid. And we are finding AREA. The formula for area of a trapezoid is 1/2h(base 1 + base 2).
Our bases in this problem are 60.5 and 75.5. We are going to addd these together and we’re going to get, 136.
Now, we must multiply 136, by its height(16). 136 x 16 = 2176.
Lastly we are going to divide by 2 and get our final answer of 1088 feet cubed.

the square root of 4,356 is an integer. without a calculator , determine what the integer is by eliminating possibilities.
Zanzabum
It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.

What is the equation of the line:
kipiarov [429]

Answer:

Final answer is y=3x-2.

Step-by-step explanation:

We have been given a graph and using that graph we need to find the equation of line.

Equation of line is given by formula y=mx+b

Where b is the y-intercept.

We see that graph crosses y-axis at (0,-2) so that means b=-2

Now plug b=-2 into formula y=mx+b. We get:

y=mx-2 ...(i)

Now find any point from the graph say (1,1) and plug into (i) to find value of slope m

1=m*1-2

1=m-2

1+2=m

3=m

Now plug m=3 into (i). We get:

y=3x-2

Hence final answer is y=3x-2.
