Answer: 10pi
Step-by-step explanation:
C = 2(pi)r
r = 5
2*(pi)*5 = C
10pi = C is the exact answer
If we make 3.14 for the pi substitution, then:
2*3.14*5=C
31.5 = C
Answer:
11
Step-by-step explanation:
44 / 11 = 4
33 / 11 = 3
7 strips
a = 30
a = 16
-a² + 46a -480 = 0
(-a + 30) (a -16) = 0
(-a)(a) + (-a)(-16) + 30(a) + 30(-16) = 0
-a² + 16a + 30a -480 = 0
-a² + 46a - 480 = 0
(-a + 30) = 0 ; (a - 16) = 0
-a = -30 ; a = 16
a = 30
To check:
a = 30
-(30)² + 46(30) - 480 = 0
-900 + 1380 - 480 = 0
480 - 480 = 0
0 = 0
a = 16
-(16)² + 46(16) - 480 = 0
-256 + 736 - 480 = 0
480 - 480 = 0
0 = 0
Answer:
F= 3x^2
Step-by-step explanation:
1) Multiplying exponents causes them to add, for instance if you were to multiply x^3 * x^4 the final product would be x^7. If you were to divide exponents then they would subtract.
2) Similarly in this problem you would determine the missing factor by dividing the product from -10x^3
3) Using the steps above, begin dividing.
-30x^5 / -10x^3
4) -30 divided by -10 is 3 and as mentioned in step number one, you subtract exponents whenever they are divided by each other. 5-3=2
5) Due to all of the steps mentioned above, The answer is 3x^2
Answer:
y = 1/2x - 2
Step-by-step explanation:
use formula y = mx + c
m = gradient
c = y intercept
