Answer is the first choice -5π/2
Answer: x=-3
Step-by-step explanation:
F(x)=9x^2-54x-19
F(x)=(x-57)(x+3)
X=57 X=-3
Answer:
B 9,4 cm
Step-by-step explanation:
The circumference of a circle is:
2πR
We know that the circumference of this circle is 59 cm, therefore, we can calculate your radio:
2πR = 59
2(3,14)R = 59
6,28 R = 59
R = 59/6,28
R = 9,394....
R ≈ 9,4
Answer:
measure of angle K is 48° or m∠K = 48°
Step-by-step explanation:
Given:
ΔJKL= ΔPQR
m∠P = 52°
m∠Q = 48°
m∠R = 80°
When 2 triangles are equal or congruent to each other then their corresponding angles are equal or congruent by congruence property.
Hence ,
m∠P = m∠J
m∠Q = m∠K
m∠R = m∠L
But m∠Q = 48° hence m∠K = 48°
Hence measure of angle K is 48°
Answer:
It would take 10 days to completely empty the rain gauge.
Step-by-step explanation:
Initial reading of rain gauge = 10 inches
<u>Every day rain evaporated by 2 inches but 1 more inch of rain was added.</u>
<u>In effect, only one inch of rain water evaporated that is everyday level decreased with 1 inch.</u>
After the end of day 1 , the reading would show 9 inches and 8 inches at the end of day 2 and similarly reading decreases linearly.
Since the reading should decrease by 10 inches it would take 10 days to completely empty the rain gauge.
