500Answer:
600
Step-by-step explanation:
Answer:
13 and 15
Step-by-step explanation:
x + (x+1) + (x+2) > 40
3x + 3 > 40
3x > 37
x > 12.34
Therfore x= 13,15 satisfy the equation
Answer:
-12
Step-by-step explanation:
Here the coefficients a, b and c are 4, 8 and -8 respectively.
-b
A formula for the axis of symmetry is x = -------
2a
-8
... which yields x = --------- = -1
2(4)
Evaluating f(x) = 4x^2 + 8x - 8 at x = -1 yields f(-1) = 4(-1)^2 + 8(-1) - 8 = -12.
The y-value of the vertex is -12. Note that the vertex lies right smack on the axis of symmetry.
Answer:
75.3074525 dgrees
Step-by-step explanation:
law of sines
29/sin(115 degrees) = 13/sin(B)
==> B = 0.418374736 rad
or 75.3074525 dgrees
Answer:
7/60
Step-by-step explanation:
7/8 times 1/3 is 7/24.
Then, 7/24 times 2/5 is 7/60
When multiplying fractions you just multiply across. For example, 7/8 times 1/3. 7 times 1 is 7 and 8 times 3 is 24. So, 7/8 times 1/3 is 7/24.
Hope this helps :)
