Answer:

in a graph the x value at the y intercept is 0
is a typical decay function
if x = 0 thus
= 1
so at 0 the function value would be A

Step-by-step explanation:
Answer: C
all shapes must equal 360 degrees
90 x the 4 angles of the square equals 360 degrees
Answer:
A=2πrh+2πr^2
Step-by-step explanation:
Answer:
m∠R=76°
Step-by-step explanation:
∠STR=∠RST=(2x+2)° (base angles of isos triangle)
2(2x+2)+(3x+1)=180 (angle sum of triangle)
4x+4+3x+1=180
7x+5=180
7x=180-5
=175
x=175÷7
=25
Hence, m∠R = (3x+1)°
= [3(25)+1]°
= (75+1)°
= 76°
