Answer:

Step-by-step explanation:

Let all the measurements be in same unit.

200 cm = 2 m

2000 mm = 2 m

Let distance jumped by Jack = x m

Distance jumped by Jerzy = x + 2

Distance jumped by Abdullah = (x+ 2) + 2 = x + 4

Total = 12.69 m

x + x +2 +x +4 = 12.69

x +x + x + 2 + 4 = 12.69

3x + 6 = 12.69

3x = 12.69 - 6

3x = 6.69

x = 6.69/3

x = 2.23 m

distance jumped by Jack =2.23m

Distance jumped by Jerzy = 2.23 + 2 = 4.23 m

Distance jumped by Abdullah = 2.23 + 4 = 6.23 m

Write an equation in slope-intercept form for the line that is parallel to y=−4x−3 and that passes through the point (−2,4).

kirill115 [55]

Answer:

The Correct option is Last one $y=-4x-4$

Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line $y=-4x-3$ is $y=-4x-4$

Step-by-step explanation:

Given:

$y=-4x-3$

To Find:

Equation of line passing through ( -2, 4) and is parallel to the line y=-4x-3

Solution:

$y=-4x-3$ ..........Given

Comparing with Slope-Intercept form,

$y=mx+c$

Where m =slope

We get

$Slope = m = -4$

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (-2 , 4) will also have the slope = m = -4.

Now the equation of line in slope point form given by

$(y-y_{1})=m(x-x_{1})$

Substituting the points and so we will get the required equation of the line,

$(y-4))=-4(x-(-2))=-4x-8\\\\y=-4x-8+4=-4x-4\\\\y=-4x-4......Equation\ of\ line$

Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line $y=-4x-3$ is $y=-4x-4$

Part B: The length of rod PR is adjusted to 17 feet. If width PQ remains the same, what is the approximate new height QR of the

Alenkinab [10]

Answer:

9.64ft

Step-by-step explanation:

Since the diagram tends to form...a right angled triangle....;

with PR = 17ft...,PQ = 14ft

then to calculate the length of QR

we use the pythagoras theorem...which is only applicable to right angled triangles

PR^2 = PQ^2 + QR^2

(17)^2 = (14)^2 + QR^2

where we make QR the subject of formula;

QR^2 = (17)^2 - (14)^2

QR = square root of( 289 - 196)

QR = square root of( 93)

;Therefore the length of QR = 9.64ft
