Answer:
Step-by-step explanation:
In exponent multiplication, if the bases are same then add the exponents.
Hello : let h =f(t)
<span>the ball hit the ground if : f(t) =0
solve : </span><span> -16t² + 20t + 6=0
</span><span>Δ = b²-4ac ... a = -16 b= 20 c =6
</span>Δ =(20)²-4(-16)(6) = 784 = 28²
t1 = (-20-28)/-32 = 48/32 =3/2
t2 =(-20+28) /-32 <span>< 0 refused
conclusion : t=3/2</span>
Answer:
make 360×each number given/15 students to start drawing
360×7/15=168°
360×5/15=120°
360×2/15=48°
360×1/15=24°
now draw each one from the radius give to the clockwise
if you don't know what's clockwise direction, see it from your house or tell anybody in your home to tell you where is clockwise
after you finish drawing, label each section by writing the names on the correct sections ( you can write in or out of the circle)
To solve for its area, we can break the figure apart.
If we splice the figure horizontally, we get a rectangle that is 30 inches long and 18 inches wide and a rectangle that is 30 inches wide and 10 inches in length.
If we solve for the two rectangles separately, we can add them to get the total area of this figure.
The area of rectangle a is 540 sq inches because 30 x 18 = 540.
The area of rectangle b is 300 sq inches because 30 x 10 = 300.
300 + 540 = 840.
The area of this figure is 840 square inches.
Hope this helps! Have an awesome day :)
