ΔT = T₂ - T₁ = 7 - (-8) = 7 + 8 = 15
In short, Your Answer would be 15 C
Hope this helps!
Answer:
B) 161.5 in²
Step-by-step explanation:
We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.
So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.
Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.
Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).
Multiply: <em>19*8.5</em> = 161.5 in²
I’m pretty sure it’s B.11x-7
Answer:
Step-by-step explanation:
<u>Using the the equation </u>
<u>The ball hits the ground, when h = 0, solving below equation:</u>
- 100t − 16t^2 = 0
- 4t(25 - 4t) = 0
- t = 0 seconds, this is the starting point when ball was hit
- 25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground
