X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.

20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257

Required equation is 92.05x + 35 = 257

What are the coordinates of the vertices of the image of rectangle WXYZ after the transformation Ro, 90•(x,y)? W’(-4,-1)
algol13

<u>Answer:</u>

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

<u>Step-by-step explanation:</u>

We have with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.

We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).

So,

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

The point P = (x, - 2/7) lies on the unit circle shown below. What is the value of x in simplest form?
miskamm [114]

Answer: x = \frac{3\sqrt{5}}{7}\\\\

Explanation:

The equation of the unit circle is x^2+y^2 = 1\\\\

Plug in y = -2/7 and solve for x

x^2+y^2 = 1\\\\x^2+\left(-\frac{2}{7}\right) = 1\\\\x^2+\frac{4}{49} = 1\\\\x^2 = 1-\frac{4}{49}\\\\x^2 = \frac{49}{49}-\frac{4}{49}\\\\x^2 = \frac{45}{49}\\\\x = \sqrt{\frac{45}{49}} \ \ \text{ ... x is positive}\\\\x = \frac{\sqrt{45}}{\sqrt{49}}\\\\x = \frac{\sqrt{9*5}}{7}\\\\x = \frac{\sqrt{9}*\sqrt{5}}{7}\\\\x = \frac{3\sqrt{5}}{7}\\\\

What is the value of the expression 8p4: 32, 1680,40,296,40,320
muminat

Answer:

1680

Step-by-step explanation:

nPr = n!/(n-r)!

Therefore;

8P4 = 8!/(8-4)!

we get;

    = 8!/4!

    = (8×7×6×5×4×3×2×1)/(4×3×2×1)

    = 40,320/ 24

    = 1680
