Answer:
3/4
Step-by-step explanation:
Since we have two points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 5 - -1)/( 4 - -4)
= ( 5+1)/(4+4)
= 6/8
= 3/4
g(x)=4x-2 ,h(x)= 5x, evaluate (h×g)(3)
Answer: 50
Step-by-step explanation:
[tex]h\:\circ \:g=h\left(g\left(x\right)\right)[/tex]
[tex]g\left(x\right)=4x-2[/tex]
[tex]=h\left(4x-2\right)[/tex]
[tex]=5\left(4x-2\right)[/tex]
[tex]=20x-10[/tex]
Substitute 3 for x:
= 20(3)-10
= 50

The equation is __=__
The cost of each ticket was $__
x=224/8
x=25+3=28
So: 28

Kamara has a square fence kennel area for her dogs in the backyard. The area of the kennel is 64 ft squared. What are the dimensions of the kennel? How many feet of fencing did she use? Explain.
Answer:
dimensions: 8 ft x 8 ft ║ 32 ft of fence she used.
Step-by-step explanation:
area of the kennel is 64 ft²as its a square, its formula for area: length²
using the formula:
length² = 64
length = √64
length = 8 ft
→ The dimensions of the kennel is 8 ft x 8 ft
Using the length, we can find; how many fencing she used:
formula used: 2 ( length + length )
using the formula:
2 ( 8 + 8 )
2 ( 16 )
32 ft

A bucket of water of mass 15 kg is pulled at constant velocity up to a platform 40 meters above the ground. This takes 16 minutes, during which time 5 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform. (Use g=9.8m/s^2.)
Answer:
4900 J
Step-by-step explanation:
The average mass of water raised is ...
(15 kg +(15 -5) kg)/2 = 12.5 kg
The work done to raise it 40 m is ...
W = mgh = (12.5 kg)(9.8 m/s^2)(40 m) = 4900 J

i need help please can i have some help
Answer:
a) Rectangle:
Length = 12 cm
Breadth = 6 cm
Area = length × breadth
= 12 × 6
= 72 cm²
b) Triangle A:
Base = 3 cm
Height = 6 cm
Area = 1/2 × base × height
= 1/2 × 3 × 6
= 9 cm²
c) Triangle B:
Base = 3 cm
Height = 6 cm
Area = 1/2 × base × height
= 1/2 × 3 × 6
= 9 cm²
d) Parallelogram:
Base = (12 - 3) = 9 cm
Height (distance between two parallel sides – the ones you use as your base) = 6 cm
Area = base × height
= 9 × 6
= 54 cm²

The graph of a proportional relationship contains the point (20, 4) .
What is the corresponding equation?
Enter your answer as a fraction in the simplest form by filling in the boxes.
Answer:
Below :D
Step-by-step explanation:
Corresponding equation:
A relationship represents a proportional diagram.
So we can express it as, y/x=k
Answer= y 1/5x
substitute (20,4)
4= 20x/.
Divide both sides by 20.
so we have.
y=1/5x.
Answer:
[tex] \frac{y - y1}{x - x1} \\ \frac{y - 4}{x - 20} \\ m = \frac{y - 4}{x - 20} \\ 1 = \frac{y - 4}{x - 20} \\ x - 20 = y - 4 \\ - y = - x - 4 + 20 \\ - y = - x + 16 \\ \frac{ - y}{ - } = \frac{ - x}{ -} + \frac{16}{ - } \\ y = x - 16[/tex]

Using the graph of f(x) and g(x), where g(x) = f(k⋅x), determine the value of k.
Answer:
1/3
Step-by-step explanation:
This is about the interpretation of the graph
From the graph, we can see the 2 lines representing function f(x) and function g(x).
Now for us to find the value of x in g(x) = k⋅f(x), we need to get a mutual x-coordinate where we can easily read their respective y-coordinate values.
We see that the best point for that is where x = -3.
For f(x), when x = -3, y = 1
For g(x), when x = -3, y = -3
we can rewrite them as;
x = -3, f(-3) = 1 and x = -3, g(-3) = -3
Let us plug in the relevant values into g(x) = k⋅f(x) to get;
-3 = k(1)
Thus; k = -1/3

Find the linear equation from this table
Answer:
y=2x+5
Step-by-step explanation:
The slope-intercept form of a linear equation is:
y=mx+b
Where m is the slope and b is the y-intercept.
We can start by finding the slope...
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can use any two x, y pairs to solve for the slope. In this case let's use (0,5) and (2,9)...
[tex]Slope=\frac{9-5}{2-0}=\frac{4}{2}=2[/tex]
The y-intercept is where the line intersects the y-axis. This means that the x value is 0. In the table we can see when the x value is 0, the y value is 5 meaning the y-intercept is 5...
y=2x+5
