Answer:

219 Seconds ; He was 1 second faster

Step-by-step explanation:

Two halfs equal one whole, meaning both of the times added will equal the full time he took:

95+124=219

219 Seconds

He was 1 second faster because:

219-218=1

4/0 is undefined. This is because any number divided by zero is undifined.

Answer:

-2

Step-by-step explanation:

Given equation is x²+px+1=0

comparing the equation with ax²+bx+c=0

then a=1,b=p,c=1

let the roots one root of the equation be A then

by question, another root is A².

we know

A(ALPHA)+A²(beta)=-b/a

A+A²=-p/1

A+A²=-p......1

again

A*A²=c/a

A³=1/1

A³=1

A=1

Now,

substituting A=1 in equation 1

1+1²=-p

2=-p

Therefore p=-2.

Answer:

[tex](x,y) = (0,1)[/tex]

Step-by-step explanation:

Given

The above table

Required

Determine the coordinates of the y intercept

Represent points on the table as:

[tex](x_1,y_1) = (4,2)[/tex]

[tex](x_2,y_2) = (8,3)[/tex]

First, calculate slope (m):

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3-2}{8 - 4}[/tex]

[tex]m = \frac{1}{4}[/tex]

For y intercept, the following coordinate point exist:

[tex](x_3,y_3) = (0,y)[/tex]

Because x = 0 at y intercept

Calculate the slope as:

[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]

The equation becomes

[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]

[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]

Cross Multiply:

[tex]4(y-2) = -4 * 1[/tex]

Divide through by 4

[tex]y - 2 = -1 * 1[/tex]

[tex]y - 2 = -1[/tex]

Make y the subject:

[tex]y = 2-1[/tex]

[tex]y = 1[/tex]

Hence, the coordinates of the y intercept is:

[tex](x,y) = (0,1)[/tex]

Step-by-step explanation:

all in order

Step-by-step explanation:

the exterior angle is equal to the sum of the interior angles on the opposite side.

As in angle BCD = angle BAC + angle ABC

113 = 72+angle ABC

angle ABC = 41

Answer:

180-113 to find the linear angle.

add that result with 72.

once found the sum, use 180 to subtract the sum to get angle B.

Answer:

4.5m

Step-by-step explanation:

The set up is a right angles triangle

Height of the shed = opposite side = 6cm

Distance of the ladder from the shed = adjacent = 4.5m

Lenght of the ladder = Hypotenuse = x

Using pythegoras theorem to find the length of the ladder

hyp² = opp²+adj²

hyp² = 0.06² + 4.5²

hyp²= 0.0036+20.25

hyp² = 20.2536

hyp = √20.2536

hyp = 4.50m

Hence the length of the ladder is 4.5m

Answer:

We conclude that the midpoint of the segment is:

Hence, option D is correct.

Step-by-step explanation:

Given the points

Finding the midpoint of the segment using the formula

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-1\right)[/tex]

so

[tex]=\left(\frac{-6-3}{2},\:\frac{-1+4}{2}\right)[/tex]

[tex]=\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]

Therefore, we conclude that the midpoint of the segment is:

Hence, option D is correct.

Answer:

They ran for 0.923 hrs and biked for 0.46 hrs

Step-by-step explanation:

First thing to do is write down the inequality of the question

5.2x + 20.8y = 14.4

10.4x + 18.2y = 18

Multiplying the whole equation by 10, so as to eliminate the decimal places, we have.

52x + 208y = 144

104x + 182y = 180

Multiplying the first equation by 2, we have

104x + 416y = 288, next we solve it simultaneously with the second equation

104x + 416y = 288

104x + 182y = 180

Subtract 2 from 1, and we have..

416y - 182y = 288 - 180

234y = 108

y = 0.46

Now, we go back and substitute for y in the earlier equation, so that

52x + 208(0.46) = 144

52x + 95.68 = 144

52x = 144 - 95.68

52x = 48.32

x = 48.32/52

x = 0.929

Answer:

[tex]\displaystyle m=1[/tex]

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-1, 0)

Point (0, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Answer:

1

Step-by-step explanation:

To do this you just need to know the slope equation y2 - y1 over x2- x1 so if you plug in 2 coordinates you can do (0,1) and (-1,0) and when you plug it into the formula you get 1/1 which is 1 so the slope is 1
