Step-by-step explanation:
the rate of change in A
10-5/4.5-3 .5
=5.
but where is the function B??
just pick two y values and it's corresponding x values
the rate of change is equal to the gradient .
change in y values divided by change in the x values.
PLEASE HELP Adam has a rectangular swimming pool. He fills it with water to a depth of 5 feet. The water has a VOLUME of 1200 cubic feet.
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :
[tex]V=lbh[/tex]
Where
l and b are length and breadth
So,
[tex]lb=\dfrac{V}{h}\\\\lb=\dfrac{1200}{5}\\\\lb=240[/tex]
The first possibillity for dimension is (10×24). Another can be (12×20).
how can I solve this 9x-5-(6-)
Answer:
9x - 5 = 6
9x = 6 + 5
9x = 11 (divide both sides by 9 to get x)
9x/9 = 11/9
x = 1.22222222222
Tonys backyard is in the shape of a trapezoid the bases of the backyard or 30 feet and 50 feet long area of the backyard is 960 ft.² sold in equation to find the height of Christophers backyard A=12(b1+b2)h
Answer:
24 feets
Step-by-step explanation:
Area of a trapezium :
A=1/2(b1+b2)h
b1 = 30 ; b2 = 50 ; Area, A = 960ft²
Inputting values into the formula :
960 = 1/2(30 + 50) * h
960 = 1/2(80)h
960 * 2 = 80h
1920 = 80h
Divide both sides by 80
1920 / 80 = 80h / 80
24 = h
Height of backyard = 24 feets

Mrs.Zomoro is 36 years old and her son is 4.When will the mother be thrice as o old as her son?
Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.

Donald has two bags of grapes.
• Bag A contains g grapes.
• Bag B contains 40% fewer grapes than bag A.
The expression g – 0.40g can be used to find the number of grapes in bag B. Donald correctly simplifies the expression until it has just one term. What is the coefficient of g in Donald’s simplified expression?
Enter your answer in the box
G for bag A could also be written as 1g
The equation could then be written as 1g - 0.40g, which if you subtract can be solved as 0.60g
The answer is 0.60g

Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )

A bird enclosure at a zoo was initially housed with 350 birds. The total population of birds in the enclosure is expected to increase every year by 5%.
Which function accurately describes the population of the birds in the enclosure, f(x), after x years?
A. f(x)=350(1.05)^x
B. f(x)=1.05(350)^x
C. f(x)=350(1.5)^x
D. f(x)=1.5(350)^x
Answer:
A
Step-by-step explanation:
The initial population is 350 so...
P = 350
The total population of birds in the enclosure is expected to increase every year by 5%
so r = 0.05
and time = X
we need to use the equation P(X) = P(1+r)^x
so by plugging in the values we get:
P(x) = 350(1.05)^x
so A is the correct answer
Jim rented a truck for one day. There was
base fee of $17.95, and there was an additional charge of 87 cents for each mile driven, Jim had to pay $153.67
when he returned the truck. For how many miles did he drive the truck?
Answer:
Jim drove the truck 156 miles
Step-by-step explanation:
Represent the number of miles driven with x.
Then the formula for the total rental cost is C(x) = $17.95 + ($0.87/mile)x, and this comes to $153.67. Solve for x:
$153.67 - $17.95 = ($0.87/mile)x, or
$135.72 = ($0.87/mile)x
Dividing both sides by ($0.87/mile), we get:
x = 156
Jim drove the truck 156 miles

Shona has to draw the line with equation y = 3x + 2. Here is her line. Explain why Shona's line cannot be correct.
Answer:
Step-by-step explanation:
The y intercept cannot possibly where it is shown. The slope is correct. The line is going from the lower left to the upper right, and the 3 makes the line closer to the y axis. For example if x = 1 then y = 3*1+2 = 5.
If x = 2, then y = 3*2 + 2 = 8 so each move of x makes a huge difference in where y is.
So lets go back to the y intercept. When x = 0, then y = 2. y = 2 is about the x axis, not below it.
Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).
What does the equation of a line imply?The equation of a line of the form y = mx + b shows a line on the coordinate plane, where for every value of x, we get a particular value of y, and m is the slope of the line. The slope is the value of tan θ, where θ is the positive angle formed between the x-axis and the line. b is the y-intercept. The y-intercept is the value of y when x = 0. This signifies that the line passes through the point (0, b).
How do we solve the given question?We are given an equation of a line y = 3x + 2, and a line of the coordinate plane.
We are asked to give the reason why the line on the plane is not the representation of the given equation.
The equation y = 3x + 2, when compared to the slope-intercept form of a line, y = mx + b, shows that the slope m = 3 and the y-intercept b = 2.
The line on the plane has a positive slope, so m = 3 can be its slope.
But the y-intercept of the drawn line is negative since it is below the origin. So b = 2 cannot be its y-intercept.
(Value of y is positive above the origin and negative below the origin)
(Value of x is positive to the right of the origin and negative to the left of the origin)
∴ Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).
