i mean it starts with a g doesnt it?
Answer:
She drove 72 miles on tuesday,
Over 3 days she drove = 50+72+38 = 160 miles
Now,
ratio = 72 : 160
= 36/80
= 9/20
= 9:20
A) 9:20
Answer:
hello
Step-by-step explanation:
The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
Then compute critical points of a derivative
.
Then evaluate at .
You will obtain global maxima and global minima respectively.
The answer is .
Hope this helps.
<span>In the question "Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table.
In which step did Susu first make an error?"
Susu made her first error in step 2, when she factored out 4 she is supposed to divide 8x by 4.
Thus the correct expression for step 2 should be 4(x^2 - 2x) = 13
To complete the solution for the equation:
4(x^2 - 2x + 1) = 13 + 4(1)
4(x - 1)^2 = 13 + 4
4(x - 1)^2 = 17
(x - 1)^2 = 17/4
x - 1 = +/- sqrt(17/4)
x = 1 +/- sqrt(17) / 2</span>
