We know that
∠1=∠5------------> by corresponding angles are congruent
so
∠5=58°
and
∠5+∠7=180----------> by supplementary angles
so
∠7=180-∠5--------> 180-58--------> 122°
the answer is ∠7=122°
Answer:
0 is your answer
Step-by-step explanation:
Solve for y. Plug in -5/3 for x
y = -3(-5/3) - 5
Simplify.
First, multiply
-3 x -5 = 15
Next, divide
15/3 = 5
Finally, subtract
y = 5 - 5
y = 0
~
1. Divide: 4+7+2•5
2. Multiply 4+7+10
3. Add from left to right 11+10
ANSWER is 21
The number of seconds that the ball will hit the ground will be 6 seconds.
<h3>What is kinematics?</h3>
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
A ball is thrown vertically upward with an initial speed of 96ft/sec. Its height after t seconds is given by
h = - 16(t - 3)² + 144
Then the number of seconds that the ball will hit the ground will be
When the ball is on the ground, the height of the ball is zero. Then we have
0 = - 16(t - 3)² + 144
16(t - 3)² = 144
(t - 3)² = 9
t - 3 = 3
t = 6

Perimiter
we have a half circle and 3 sides of a rectangle
half circle
circumfernce=2pir
half of that is 1/2 2pir or pir
so
diameter=8
radius is 1/2 of that or 4
so
that arc is 4pi
the 3 sides are 8+9+9 or 26
if we use pi=3.141592
4pi+26=38.566368
rounded we get
38.57
the closest one is C
answer is C
