Answer:
D is the solution
Step-by-step explanation:
1.25 = 1.25/100= 125%
1 1/4= 1 25/100 = 1.25
125%= 125/100= 1.25 and 1 1/4
Tony = x
Mauricio = 4x
If Tony hits at the game, then Mauricio will hit 4 times as many times + the 20 at practice, so
4x + 20
That means if Tony hit 1, Mauricio will hit
4(1) + 20 = 24
If Tony hits 2, Mauricio will hit
4(2) +20 = 28
Your answer should be the expression
4x + 20
The plane flew 1,080 miles in 2.5 hours
Answer:
12.
Step-by-step explanation:
Average rate of change = (value of the function when x = 9 - value when x=3)
/
(9 - 3)
= f(9) - f(3) / (9-3)
= (9^2 - 3^2) / (9-3)
= 72 / 6
= 12.
Answer:
P and Q are two points on the line x-y+1=0 and are at a distant of 5 units from the origin. Find the area of triangle POQ.
Step-by-step explanation:
P and Q are the intersection points of
x-y+1 = 0 and the circle x^2 + y^2 = 25
sub y = x+1 into the circle
x^2 + (x+1)^2 = 25
x^2 + x^2 + 2x + 1 - 25 = 0
x^2 + x - 12 = 0
(x+4)(x-3) = 0
x = 3 or x = -4
y = 4 or y = -3
so P(3,4) and Q(-4,3) are our two points
Height of triangle.
h = |0 - 0 + 1|/√2 = 1/√2
PQ = √( (-7)^2 + 1^2) = √50 = 5√2
area POQ = (1/2)(1/√2)(5√2) = 5/2 square units
