Answer:
40
Step-by-step explanation:
2 • (3(5 + 2) - 1) =
Start with the innermost parentheses.
= 2 • (3(7) - 1)
Now do the multiplication inside the parentheses.
= 2 • (21 - 1)
Do the subtraction inside the parentheses.
= 2 • 20
= 40
Since the minimum value is 0 and axis of symmetry is -2 this means that the vertex is at -2,0 now with the y intercept of 4. You can now plug the values into Vertex form which will be y=a(x-h)^2+k. a being the shrink or stretch of the parabola, h being the x value of the vertex, and k being the y value of the vertex. with all of that plugged in it should look like y=(x+2)^2. You can check this equation by plugging in 0 as x which should find the y intercept of 4. So it should then look like y=(0+2)^2 -> y=(2)^2 -> y=4
Answer:
4³
Step-by-step explanation:
16 x 4
(4 x 4) x 4 = 64
460/8 = 57.5 They were going 57.5 mph
661.25/57.5mph = 11.5
It will take them 11 and a half hours go get wherever they're going.
R=25
a^2+b^2=c^2
7^2+24^2c^2
49+576=c^2
625=c^2
c=25
