Answer:
Step-by-step explanation:
x=25
Answer:
Even
Step-by-step explanation:
The function Y=-6x^6-5x^2- 2 is a polynomial. A polynomial function is a function where a whole number exponent greater than 1 is on the variable. All polynomial functions have a degree known as the highest exponent. This degree also determines if the functions is even, odd or neither.
The highest exponent on the polynomial is 6 which is an even number. This polynomial is even.
Answer:
Katherine and Beatrice will meet after 2.5hrs.
Step-by-step explanation:
Given:
Distance between Katherine and Beatrice when they start moving towards each other= 20 miles
Speed at which Katherine runs =5 mph
Speed at which Beatrice walks =3 mph
To Find:
Time taken for Katherine and Beatrice to meet each other
Solution:
Let assume number of hours after which Katherine and Beatrice = x hrs
Distance = speed x time
Distance travelled by Katherine in x hours =
= 5x
Distance travelled by Beatrice in x hours =
= 3x
Total distance covered together by Katherine in x hours and Beatrice in x hours is 20 miles .
=> 5x + 3x = 20
=>8x = 20
=> 
=> 
=> x=2.5
Number of hours after which Katherine and Beatrice meets = x hrs = 2.5hrs
Answer: .01
Step-by-step explanation:
Answer:
measure of arc QR = 28.8°
Step-by-step explanation:
Full circle = 100% = 360°
Measure of arc QR = percentage covered by arc QR / 100 × 360
arc QR covers 8%
Therefore:
measure of arc QR = 8/100 × 360°
measure of arc QR = 0.08 × 360°
measure of arc QR = 28.8°
