Answer: both equal 82

Step-by-step explanation: When you have parallel lines with a transversal, all the angles are either the same as the given angle or 180- the angle given. This is because they are all supplementary or equal. 1, 3, 5, and 7 are equal, 2, 4, 6, and 8 are equal. 180-98=82

In a memory experiment, Alice is able to memorize words at a rate given by m '(t)= - 0.009t^2 + 0.6t. In the same memory exper

White raven [17]

Answer:

1) Ben, 2) $\Delta = 2$ , 3) $\dot m = 2.7$ , 4) $\dot M = 2.9$

Step-by-step explanation:

1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.

2) The number of words can be estimated by integrating the function:

Alice

$\Delta m = -0.003\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta m = 27$

Ben

$\Delta M = -0.001\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta M = 29$

$\Delta = \Delta M - \Delta m$

$\Delta = 2$

3) The average amount of words per minute is:

$\dot m = \frac{27}{10}$

$\dot m = 2.7$

4) The average amount of words per minute is:

$\dot M = \frac{29}{10}$

$\dot M = 2.9$

Shelby bought a 2-ounce tube of blue paint. She used 2/3 ounce to paint the water, 3/5 ounce to paint the sky, and some to paint

irina1246 [14]

Answer:

The amount of ounce used for paint is $\frac{9}{15} ounce$

Step-by-step explanation:

used amount for water is $\frac{2}{3}$ ounce.

used amount for sky is $\frac{3}{5}$ ounce.

thus, the total amount used is $\frac{2}{3}$ + $\frac{3}{5}$

= $\frac{19}{15}$

Thus the total unused amount is 2 - $\frac{19}{15}$ = $\frac{11}{15}$ .

But the remaining amount is $\frac{2}{15}$ .

Thus used amount for flag is $\frac{11}{15}$ - $\frac{2}{15}$

= $\frac{9}{15}$

triangle ABC is reflected about the line Y equals negative X to give triangle ABC with vertices A (-1, 1), B (-2, -1), C (-1,0).

Amiraneli [1.4K]

Answer:

A'(-1, 1)
B'(1, 2)
C'(0, 1)

Step-by-step explanation:

Reflection across the line y = -x is accomplished by the transformation ...

(x, y) ⇒ (-y, -x)

Then the images of the given points are ...

A(-1, 1) ⇒ A'(-1, 1) . . . . this point is on the line of reflection, so doesn't move

B(-2, -1) ⇒ B'(1, 2)

C(-1, 0) ⇒ C'(0, 1)
