Which line is parallel to 4x + 2y = 0?A. y=2x+3B. -1/2×+3C. y=-2x+3D. y=1/2x+3

Line A is parallel to line B if line A and B have the same slope and have the same or different y-intercept.

Convert the standard form equation to slope-intercept form as it will be easier to see the slope.

Solve for y.

4x + 2y = 0
2y = -4x <-- Subtract 4x from each side
y = -2x <-- Divide both sides by 2

In the slope-intercept form y = -2x, a y-intercept of 0 is implied

Now find a slope-intercept form equation that has the same slope as y = -2x

So, the answer is C y = -2x + 3.

Convert to slope - intercept form:-
2y = -4x
y = -2x so the slope of this line is -2

parallel lines have same slope

So its C.

Take the integral:

$\large\begin{array}{l} \mathsf{\displaystyle\int\!3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\int\!\frac{1}{2}\cdot 2\cdot 3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^{2x-1}\cdot 2\,dx\qquad(i)} \end{array}$

$\large\begin{array}{l} \textsf{Substitute}\\\\ \mathsf{2x-1=u\quad\Rightarrow\quad 2\,dx=du}\\\\\\ \textsf{so (i) becomes}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^u\,du}\\\\ =\mathsf{\dfrac{1}{2}\cdot \dfrac{1}{\ell n\,3}\,3^u+C}\\\\ =\mathsf{\dfrac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}$

$\large\begin{array}{l} \boxed{\begin{array}{c}\mathsf{\displaystyle\int\!3^{2x-1}\,dx=\frac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}}\qquad\checkmark \end{array}$

Plz, help me with this question!

Hatshy [7]

Answer:

A. 24

Step-by-step explanation:

Angles in a triangle add up to equal 180

Thus, 66 + 90 + x = 180

66 + 90 = 156

156 + x = 180

180 - 156 = 24

Hence, x = 24

Note: There is a right angle indicated by the square inside of the triangle. A right angle has a measure of 90 degrees. So Just in case you were wondering that's where the 90 cam from

Question

denpristay [2]

V= π r^2 h

r= radius
h= height

If the radius was 10 ft and the height was 12ft then the answer be about 3769.91.

However if it was reversed and the radius was 12ft and the height was 10 ft then the answer would be about 4523.89.

3769.92≈ π 10^2 12

or

4523.89≈ π 12^2 10

Answer:

Step-by-step explanation:

The central angle is equal to the arc that subtends it , then
