F(x) = 3x - 2
f(3) = 3(3) - 2
f(3) = 9 - 2
f(3) = 7
Answer:
A. complementary
Step-by-step explanation:
Complementary is when 2 angles add up to 90°. Therefore, the angle in the image shown is a 90° angle. Hope this helps :)
Jill lost 1/3
Bill lost 1/6
and Jack lost 1/4
Make a common denominator - let's use 12
Jill lost 4/12
Bill lost 2/12
Jack lost 3/12
Add them together = 9/12
reduce by dividing by 3.
total of 3/4 spilt
48 divided into 4 parts then multiplied by 3 of those parts
48 / 4 * 3 = 36
Answer:
The height of the roof is 534.8 feet.
Step-by-step explanation:
Let h be the height of the roof.
We know the formula
Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0
Now, we have
v = -185 feet per second
g = 32 feet per square second
On substituting these values, we get
The height of the roof is 534.8 feet.
Answer:
Jake is 9, and Jake's dad is 43.
Step-by-step explanation:
Ok, let's start off by putting a variable for Jack's age, A.
We know that Jack's father is 2 less than 5 times, so we can write his as 5x -2.
Now let's make an equation:
52 = x + 5x - 2
We need to isolate the x-values so we need to add 2 on both sides:
54= x + 5x
No we need to add the like terms:
54 = 6x
Finally, we just divide by 6 on each side.
Now we know X = 9 but we're not done yet :)
So because Jake's dad is almost 5 times as much, we first multiply Jack's age by 5. We get 45 but we need to subtract 2 which leaves us with 43.
