your teacher is introducing algebra
Answer: you will need approximately 23 grams
Step-by-step explanation: but thats approximately
Y= -x+1 because the slope is negative
Answer:
27π cm²
Step-by-step explanation:
step 1
Find the area of the complete circle
The area of the circle is equal to
A=πr²
we have
r=9 cm
substitute
A=π(9)²=81π cm²
step 2
Remember that the area of complete circle subtends a central angle of 360°
so
using proportion
Find the area of a sector formed by a central angle that measures 120°
81π/360°=x/120°
x=120°*81π/360°
x=27π cm²
Substitute -8 for t in <span>h(t)=-2(t+5)^2+4:
h(-8) = -2(-8+5)^2 + 4 = -2(-3)^2 + 4 = -2(9) + 4 = -18 + 4
h(-8) = -18 + 4 = -14 (answer)</span>
