Answer:

942.48

Step-by-step explanation:

use the formula v=bh

step 1:find base use the formula to find the area of the circle

step 2:then multiply your answer of base with your height

like this $\pi5^{2}$ then 78.59(12)

Write an equation for the line perpendicular to 4x - 12y = 2 and passing through point (10, -1)

MrMuchimi

Answer:

3x+y=-31

Step-by-step explanation:

$4x - 12y = 2\\12y = 4x-2\\y=\frac{x}{3}-\frac{1}{6}$

Slope of perpendicular line is -3.

$y=-3x+b$

Sub in the point (10, -1)

$-1=-3(10)+b\\-1=30+b\\b=-31\\y=-3x-31\\3x+y=-31$

Factor the four term polynomial by grouping. 10x^3-15x^2+6x-9

goldfiish [28.3K]

Answer:

(5x² + 3) (2x-3)

Step-by-step explanation:

10x³ - 15x² + 6x - 9 (rearrange)

10x³+ 6x - 15x² - 9 (group using parentheses)

(10x³+ 6x) - (15x² + 9) (factor out 2x from first term and 3 from second term)

2x (5x²+ 3) - 3(5x² + 3) (factor out (5x²+3) )

(5x² + 3) (2x-3) (answer)

In the diagram, WZ=StartRoot 26 EndRoot.

gogolik [260]

Answer:

$P = 8 + 2\sqrt{26}$

Step-by-step explanation:

Given

$W = (-2, 4)$

$X = (2, 4)$

$Y = (1, -1)$

$Z = (-3,-1)$

Required

The perimeter

First, calculate the distance between each point using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 -y_2)^2$

So, we have:

$WX = \sqrt{(-2- 2)^2 + (4-4)^2 } =4$

$XY = \sqrt{(2- 1)^2 + (4--1)^2 } =\sqrt{26}$

$YZ = \sqrt{(1- -3)^2 + (-1--1)^2 } =4$

$ZW = \sqrt{(-3--2)^2 + (-1-4)^2 } =\sqrt{26}$

So, the perimeter (P) is:

$P = 4 + \sqrt{26} + 4 + \sqrt{26}$

$P = 8 + 2\sqrt{26}$

tanji creates a "square, circle" repeating pattern. Kenji creates a "Square, circle, trianglr, cricle" repeating pattern. if bot

RoseWind [281]

Both tanji & kenji have same number of circles i.e. 50 .

Step-by-step explanation:

Here we have , tanji creates a "square, circle" repeating pattern. Kenji creates a "Square, circle, triangle, circle" repeating pattern. if both tanji and kenji have 100 shapes in their patterns, . We need to find that which pattern contains more circles .Let's find out :

tanji creates a "square, circle"

it's given that tanji has 100 shapes and he is repeating this pattern . In this pattern circle comes 1 every time out of 2 shapes :

Total number of times circle = $\frac{100}{2}(1)$

Total number of times circle = $50$

Kenji creates a "Square, circle, triangle, circle"

it's given that tanji has 100 shapes and he is repeating this pattern . In this pattern circle comes 2 every time out of 4 shapes :

Total number of times circle = $\frac{100}{4}(2)$

Total number of times circle = $50$

Both tanji & kenji have same number of circles i.e. 50 .
