A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
Answer:
150 cm/s
Step-by-step explanation:
We have that the area of a rectangle is as follows:
a = l * w
they ask us to change the increase in area with respect to time, therefore, if we derive with respect to t we are left with:
da / dt = w * (dl / d) t + l * (dw / dt)
From the statement we know that:
l = 20 cm
w = 15 cm
dl / dt = 6 cm / s
dw / dt = 3 cm / s
replacing each value we have:
da / dt = 15 * 6 + 20 * 3
da / dt = 150
Which means that 150 cm / s increases the area of the rectangle in relation to time
Sin J = cos K
sin J = cos (90 - J)
K = 90 - J
sin 60 = cos (90 - 60) = cos 30
Therefore, 60°, 30° satisfy the condition sin J = cos K.
Hello,
When you have an polygon inscribed in a circle, the opposite angles are supplementary.
Therefore, we can write and solve the following equation.
2x + 3 + 4x + 3 = 180
6x = 174
x = 29
If you substitution 29 into the expression for C, you will find that C = 59.
2(29) + 1 = 59
Good luck,
