Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>
2
A = √15cm²
Answer:
(a) 24 ft
(b) 2.5 s
Step-by-step explanation:
At t=2
h=-2(2)^{2}+10(2)+12=12+20-8=24 ft
Therefore, height after 2 s=24 ft
(b)
As it hits the ground, t is maximum and at maximum t, we differentiate the function to have
h=-4t+10 and h=0 hence
4t=10 hence t=10/4=2.5 seconds
Answer:
first you add then you subtract
Step-by-step explanation:
Gina must divide a fraction by a whole number.
The amount of nuts in each bag will be less than 7/8 because 7/8 is divided by 4.
Gina will be able to put 7/32 pounds of nuts in each bag.
