M∠1=3y+6. Help please

1 answer:

6 0

Since the figure has both sides congruent and 90 degree angle, the figure is a square. That means that the angle of the diagonals are 90 degrees so m∠1=90. This means 90=3y+6 so y is 28

Carl earned grades of 62, 78, 59, and 89 on four math tests.

QveST [7]

Answer:

Mean, m = 72

Step-by-step explanation:

It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.

It is required to find the mean of his grades.

Mean of a data is given by :

$m=\dfrac{\text{sum of observations}}{\text{total no of observations}}$

Sum of observations is 62 + 78 + 59 + 89 = 288

Total no of observations are 4

So, mean of his grades is :

$m=\dfrac{288}{4}\\\\m=72$

So, the mean of his grades is 72.

Find the points on the curve y = 2x3 + 3x2 − 12x + 1 where the tangent line is horizontal. (x, y) = (smaller x-value) (x, y) = (

vesna_86 [32]

Thinking about the graph of y, the rate of change is zero whenever there is an extremum.

First, differentiate y.

$y'=6x^2+6x-12$

Next, find the zeros of y' by factoring.

$6(x^2+x-2)=0 \\ x = -2, x = 1$

Now, we substitute these x-values into the original equation to find the coordinates.

$(-2,21), (1,-6)$
