C. 402
323.24 rounded = 323
79.13 rounded = 79
323 + 79 = 402
Answer: 49.44807
Round that however you need to. Unfortunately the rounding instructions on the screenshot are cut off, so I cannot see what that part says.
=======================================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(22) = h/132
h = 132*sin(22)
h = 49.44807
First find slope intercept for our equation
-6x+3y=18.9
3y=6x+18.9
y=2x+6.3
Since b is y intercept, y intercept is (0,6.3)
Now in x intercept y is equal to 0.
So substitute it for our equation.
0=2x+6.3
-2x=6.3
x=-3.15
So x intercept is (-3.15, 0)
Answer:
The conclusion is wrong
Step-by-step explanation:
The following steps are given
Required
The error
Going through the steps, we can see that there are no mistakes in any of the step.
However, the conclusion that there are infinitely many solutions is wrong
because the solution actually has no solutions.
Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2
Step-by-step explanation:
(a + 3) * (-2a^2 + 15a + 6b^2)
We open the brackets with (a + 3)
a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)
Opening the brackets
= a * -2a^2 = -2a^3
a * 15a = 15a^2
a * 6b^2 = 6ab^2
3 * -2a^2 = -6a^2
3 * 15a = 45a
3 * 6b^2 = 18b^2
Let's arrange those values weve gotten together ,don't forget the signs each carry
= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2
Collect the like terms
= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2
= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2
