As shown in the picture the entirety of DF is equal to 5x + 7. So, you have to find the value of x to find the answer. To do this set 5x + 7 even to 8 + 2x + 5 since that is just DF broken into two segments. Here’s my work:

8 + 2x + 5 = 5x + 7 5x + 7 = DF
6 = 3x 5(2) + 7 = DF
2 = x 10 + 7 = DF
17 = DF

Remy walked to a friend’s house m miles away at an average rate of 4 mph. The m-mile walk home was at only 3 mph, however. Express as a fraction
a) Time Remy spent walking home.
b)Time Remy spent walking.

(Answer both (a) and (b).

Answers

Answer:

a) m/4 miles per hour

b) 7m/12 miles per hour

Step-by-step explanation:

Mathematically, at any point in time;

Time = distance/speed

The distance here at any point is m mph

a) For the time spent walking home

Time = m/4 miles per hour

b) We add the time walking to the friend’s house and the time that it took to walk home

That would be;

m/4 + m/3 = 7m/12 miles per hour

Emily is observing the velocity of a cyclist at different times. After four hours, the velocity of the cyclist is 14 km/h. After nine hours, the velocity of the cyclist is 4 km/h

Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist different times. Show your work and define the variables used.

Part B: How can you graph the equations obtained in Part A for the first 10 hours?

Answers

Emily starts from rest so that the velocity is zero at 0 hours.

Define the function v(t) for velocity in km/h, and t in hours.

Part A
From t=0 to t=4, v changes from 0 to 14.
Let v(t) = mt + b
The slope is
m = 14/4 = 3.5, and the y-intercept is
b = 0.
Therefore
v(t) = 3.5t, for 0 ≤ t ≤ 4

Fromt=4 to t=9, changes from 14 to 4.
Let v(t) = mt + b
The slope is
m = (4 - 14)/(9 - 4) = -2
Therefore
v = -2t + b
When t=4, v=14, therefore
14 = -2*4 + b = -8 + b
22 = b
v(t) = -2t + 22, for 4 < t ≤ 9.

Answer:
The equation for the velocity is
v(t) = 3.5t, 0 ≤ t ≤ 4
= -2t + 22, 4 < t ≤ 9

Part B
The equation for velocity is a piecewise function that is graphed as shown below. If we assume that the second part of the equation is valid at t=10, then
v(10) = -2*10 + 22 = 2 km/h

What is the length of the hypotenuse?

HELP

Answers

Answer:

58 yards

Step-by-step explanation:

The Pythagorean Theorem states that:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where c is the hypotenuse, and a and b are the two legs of the right triangle. Substituting in 40 and 42 for a and b, respectively:

[tex]40^{2} +42^{2} =c^{2}[/tex]

Now, we isolate c:

[tex]c= \sqrt{40^{2} +42^{2} }[/tex]

Therefore, c is equal to 58, so the hypotenuse is 58 yards

The buildings of a university are mapped on a coordinate grid with the origin being at library.

How far is it from the Math building to the History building?
units

Answers

Answer:

Step-by-step explanation:

The distance between from Math building to history building is 5 units

What is Distance Formula?

The distance between coordinate P(x , y) and coordinate Q(a , b) is calculated using the distance formula: d= √(x-a)²+(y-b)²

The Math building is located at the point (1,5)

The History building is located at (4,9).

Using distance formula:

d= √(x-a)²+(y-b)²

=√(4-1)²+(9-5)²

= √9+16

= √25

= 5 units

Hence, the distance between Math and History building is 5 units.

The 4th one and first one

it wants us to solve for x and i’m very confused

x= ?

Answers

Answer:

x = 6

Step-by-step explanation:

∡J = ∡K and ∡M = ∡L

because this is an isosceles trapezoid

∡J + ∡M = 180°

because angles at opposite bases are supplementary

then ∡J + ∡M = 180°

∡J = (7x + 2)°

∡M = ∡L = (25x - 14)°

so:

(7x + 2 + 25x - 14)° = 180°

(32x - 12)° = 180°

32x = 180 + 12

32x = 192

x = 6

Answer:

x= 8/9

Step-by-step explanation:

7x + 2 = 25x - 14

-7x -7x

2 = 18x - 14

+14 +14

16 = 18x
