Write an equation of the line that passes through (2, -3) and is perpendicular to the line y=-2x-3

Natalija [7]

Answer:

$y=\frac{1}{2} (x-2)-3$ or $y=\frac{1}{2} x-4$

Step-by-step explanation:

The perpendicular slope is the opposite-reciprocal of the original slope:

Perpendicular slope of -2 is $\frac{1}{2}$

Write the equation in point-slope form ( $y=a(x-h)+k$ ):

$y=\frac{1}{2} (x-2)-3$

Convert to slope-intercept form if needed:

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

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

Consider the following formula used to estimate height, h, of a seedling after w weeks since planting:

svp [43]

Answer:

Option B. $w=5h-8$

Step-by-step explanation:

we have

$h=(\frac{1}{5})w+(\frac{8}{5})$

Solve for w

That means ----> isolate the variable w

Multiply by 5 both sides to remove the fraction

$5h=w+8$

subtract 8 both sides

$5h-8=w+8-8$

$5h-8=w$

Rewrite

$w=5h-8$

One angle measure in an acute triangle is 38°. What could the measure of one of the other angles be?

devlian [24]

Sum of all the angles in a triangle = 180 degrees.
it's given is an acute angle so <90
degrees now one is 38 the sum of other two would be 142 now here 27 is not possible because then the third angle, would be 115 degrees.

hope this help

skelet666 [1.2K]

We don't need to know the trampoline diameter, it's a trick

the legnth of the metal fram is the circumference
C=pid
d=14
c=14pi
pi=3.14
c=14*3.14
c=43.96
round
C=44

answer is 44 feet
