Step-by-step explanation:
(2,-8) and has a slope of 4
Answer:
The equation of the line is;
y = 4x - 16
Step-by-step explanation:
Here, we want to find the equation of a line that passes through the point (2,-8) and has a slope of 4
To get this equation, we are going to use the point-slope form
Thus, we have it that;
y-y1 = m(x-x1)
y -(-8) = 4(x-2)
y + 8 = 4x - 8
y = 4x -8-8
y = 4x - 16

Step-by-step explanation:
Given
[tex]\angle J=90^{\circ }[/tex]
HI=88 ft
IJ=62 ft
From the figure, we can write

A lug nut is used to secure a wheel on a vehicle. Most lug nuts are shaped like regular pentagons or regular hexagons. However, some lug nuts are shaped like regular heptagons (7 sided). What is the measure of each interior angle of a regular heptagon lug nut? Round your answer to the nearest degree
Answer:
[tex]129^{\circ}[/tex]
Step-by-step explanation:
n = Number of sides of a polygon = 7
The interior angles of a polygon is given by
[tex]\theta=\dfrac{(n-2)180^{\circ}}{n}[/tex]
[tex]\Rightarrow \theta=\dfrac{(7-2)\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{5\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{900^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=128.57^{\circ}\approx 129^{\circ}[/tex]
Each interior angle of a heptagonal nut is [tex]129^{\circ}[/tex].

What is mean by Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
We have to given that;
The expression of the inequality is,
⇒ m/ 8 < 4
Now, We can simply the expression as;
⇒ m/ 8 < 4
⇒ m/ 8 - 4 < 0
⇒ (m - 32)/8 < 0
⇒ m - 32 < 0
⇒ m < 32
Therefore, The solution of inequality m/8 < 4 is,
⇒ m = 32

A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode? Firework A 240 ft/s Firework B 200 ft/s
Answer: 1.50 seconds
Step-by-step explanation:
Let x = Time taken by Firework A to explode( in seconds ).
Time taken by Firework B = x+ 0.25 seconds
Distance covered = Time × Speed
Distance covered by Firework A = 240 x
Distance covered by Firework B = 200 (x+0.25) = 200x+50
When both at same height , then
240x = 200x+50
⇒ 240x- 200x =50
⇒40x =50
⇒ x = 1.25
Total time = x+ 0.25 = 0.25+ 1.25 = 1.50 seconds
Hence. after Firework B launches it will take 1.50 seconds to launch.
