Answer:
$6.21
Step-by-step explanation:
1 apple = $0.60
3 apples = $1.80 (Multiply 0.60 by 3)
2 bananas = $1.00 (Multiply 0.50 by 2)
1 quart of yoghurt = $4.50
Add the prices up first:
1.80 + 1.00 + 4.50 = $7.30
7.30 off 15% = $6.21
Answer:
Option (4)
Step-by-step explanation:
From the figure attached,
∠b = 75° [Vertical angles]
If the lines f and g are parallel then,
∠b = ∠c [Corresponding angles]
Therefore, ∠c = 75°
Since m∠c + m∠d = 180° [Supplementary angles]
75° + m∠d = 180°
m∠d = 180° - 75°
m∠d = 105°
Therefore, measure of angle d should be equal to 105° to prove f and g are parallel.
Option (4) will be the answer.
(a) Compare your quadratic for h to the general quadratic ax² +bx +c. Perhaps you can see that ...
a = -16
b = 128
You use these numbers in the given formula to find the time when the ball is highest.
t = -b/(2a) = -128/(2(-16)) = 4 . . . . . . the time at which the ball is highest
(b) Evaluate the quadratic to find the height at t=4.
h = -16(4)² +128(4) +21
h = -256 +512 +21
h = 277
The maximum height of the ball is 277 ft.
Hope it helped you!
