133  = 38 + m angle adjacent to n  (exterior angle of triangle theorem)
so m this angle =  133 - 38 = 95 degrees
Thus m  n = 180 - 95  = 68 degress

Its option A.

<span>An exterior angle of a triangle is equal to the sum of the opposite interior angles
</span>
so
n = (180 - 133) + (180 - 142)
n = 47 + 38
n = 85

answer is A. 85

Answer:

The line equation in slope-intercept form is:

y\:=-\frac{2}{5}x+4

Hence, option D is true.

Step-by-step explanation:

Given the points

  • (0, 4)
  • (5, 2)

Finding the slope between the points

\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

m=\frac{2-4}{5-0}

m=-\frac{2}{5}

As the y-intercept is obtained by setting the value x = 0.

As we know that when x = 0, the vale of y-intercept y = 4

so the y-intercept is b = 4.

As the slope-intercept form is

substituting the slope m = -2/5 and the y-intercept b=4

y  = mx+b

y\:=-\frac{2}{5}x+4

Therefore, the line equation in slope-intercept form is:

y\:=-\frac{2}{5}x+4

Hence, option D is true.

Find the 76th term of the arithmetic sequences 16 14 12
grigory [225]

Answer:

a₇₆ = - 134

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 16 and d = a₂ - a₁ = 14 - 16 = - 2, then

a₇₆ = 16 + (75 × - 2) = 16 - 150 = - 134

A hemisphere has an area of 256 pi cm^2. What is its volume?
Amanda [17]
\bf \begin{array}{llll}&#10;\textit{surface area of a sphere}\\\\&#10;A=4\pi r^2&#10;\\\\\\&#10;\textit{a hemisphere is half that}\\\\&#10;A=\cfrac{4\pi r^2}{2}\implies A=2\pi r^2&#10;\end{array}\qquad r=radius&#10;\\\\\\&#10;\textit{now, we know the area is }256\pi \implies 256\pi =2\pi r^2&#10;\\\\\\&#10;\cfrac{256\pi }{2\pi }=r^2\implies \sqrt{128}=r\implies \boxed{8\sqrt{2}=r}&#10;\\\\&#10;-----------------------------\\\\

\bf \textit{volume of a sphere}\\\\&#10;V=\cfrac{4}{3}\pi r^3\qquad r=radius&#10;\\\\\\&#10;\textit{a hemisphere is half that}\\\\&#10;V=\cfrac{\frac{4}{3}\pi r^3}{2}\implies V=\cfrac{\frac{4\pi r^3}{3}}{\frac{2}{1}}\implies V=\cfrac{4\pi r^3}{3}\cdot \cfrac{1}{2}&#10;\\\\\\&#10;V=\cfrac{2\pi r^3}{3}&#10;\\\\\\&#10;\textit{now, we know the radius is }8\sqrt{2}\implies V=\cfrac{2\pi (8\sqrt{2})^3}{3}&#10;\\\\\\&#10;V=\cfrac{2\pi (8^3\sqrt{2^3})}{3}\implies V=\cfrac{2\pi \cdot 512\cdot 2\sqrt{2}}{3}&#10;\\\\\\&#10;\boxed{V=\cfrac{2048\pi \sqrt{2}}{3}}
