Answer: 21
Step-by-step explanation:
4 • 3 = 12
3•3=9
12+9= 21
Answer:
-16
Step-by-step explanation:
Replace all t with -5:
w(t) = 3t - 1
w (-5) = 3(-5) - 1
w(-5) = -16
Answer:
The radius will change from 0.977 feet to 1.49 feet.
Step-by-step explanation:
The area of a circle with radius r is given by πr².
If the are of the circle is 3 square feet, then πr² = 3, ⇒ r²=
⇒ r² =0.9545, ⇒ r=0.977 feet.
If the area of the circle changes to 7 square feet, then its radius will change to r²= =2.228, ⇒ r =1.49 feet.
Therefore, the radius will change from 0.977 feet to 1.49 feet. (Answer)

We can use the fact that a cyclic quadrilateral (i.e. a quadrilateral inscribed in a circle) has the opposite angles supplementary, therefore
2x+(2x+4) = 180
Solving for x:
4x+4=180
4x=180-4=176
x=176/4=44 °
=>
angle O = 2x = 88 °
angle Q=180-O=180-88 = 92 °
Similarly,
(3y+8)+y= 180
=> y=43 °
=>
P=y=43 °
R=180-43=137 °
