I can help you do u have a question or just need a tutor?
Step-by-step explanation:
The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water.
The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 1.45x + 13.90
If the Johnson family used 200 ft3 more water this month than last month, then they can expect
A. an increase in their water bill of $2.90.
B. an increase in their water bill of $27.80.
C. a decrease in their water bill of $2.90.
D. a decrease in their water bill of $27.80.
Answers
Answer: A
Step-by-step explanation:
In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.
An artist’s canvas has sides measuring 3x – 3 and 4x + 1 inches.
What is the area of the canvas? Show all work.
The artist laid the canvas flat on the floor and poured some paint in the center. The paint flows at a rate of r(t) = 4t where t represents time in minutes and r represents how far the paint is spreading on the canvas. The area of the paint can be expressed as A[r(t)]= πr². What is the area of the circle created by the paint?
If the artist wants the circle to be at least 1300 in², will it be that large in 5 minutes? Support your answer with your work.
Answers
Step-by-step explanation:
Finding the area of the canvas:
The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:
Area = (3x - 3) * (4x + 1)
= 12x^2 + x - 3
Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.
Finding the area of the circle created by the paint:
The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.
Substituting the value of r(t) = 4t into the formula, we get:
A[r(t)] = π(4t)^2
= 16πt^2
Therefore, the area of the circle created by the paint is 16πt^2.
Determining if the circle will be at least 1300 in² in 5 minutes:
To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:
A[r(5)] = 16π(5)^2
= 400π
Approximating the value of 400π, we get approximately, 1256.64.
Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².
A = (3x - 3)(4x + 1)
A = 12x² - 8x - 3
The paint is spreading at a rate of r(t) = 4t, which means that the radius of the circle is also increasing at a rate of 4t. Therefore, the area of the circle can be expressed as:
A[r(t)] = πr²
A[r(t)] = π(4t)²
A[r(t)] = 16πt²
We want to find out if the area of the circle will be at least 1300 in² in 5 minutes. So we need to substitute t = 5 into the equation for the area of the circle:
A[r(5)] = 16π(5)²
A[r(5)] = 400π
The area of the circle created by the paint after 5 minutes is 400π in², which is approximately 1256.64 in². Since this is less than 1300 in², the circle will not be that large in 5 minutes.

The area of the rectangle below is 90 cm². Form a quadratic equation involving n and solve it to find the value of n.
Answers
Answer:
2n² + 5n - 102 = 0
n = 6
Step-by-step explanation:
The formula for the area of a rectangle is:
\(\boxed{A=w \cdot l}\)
where w is the width and l is the length.
From inspection of the given rectangle:
w = (n + 4)l = (2n - 3)Given that the area of the rectangle is 90 cm², then A = 90.
Substitute the values of A, w and l into the formula:
\(\implies 90=(n+4)(2n-3)\)
Switch sides:
\(\implies (n+4)(2n-3)=90\)
Expand the left side of the equation using the FOIL method:
\(\implies 2n^2-3n+8n-12=90\)
\(\implies 2n^2+5n-12=90\)
Subtract 90 from both sides:
\(\implies 2n^2+5n-12-90=90-90\)
\(\implies 2n^2+5n-102=0\)
To solve a quadratic in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.
\(\implies ac=2 \cdot (-102)=-204\)
\(\implies b=5\)
Two numbers that multiply to -204 and sum to 5 are:
17 and -12Rewrite b as the sum of these two numbers:
\(\implies 2n^2+17n-12n-102=0\)
Factor the first two terms and the last two terms separately:
\(\implies n(2n+17)-6(2n+17)=0\)
Factor out the common term (2n + 17):
\(\implies (n-6)(2n+17)=0\)
Apply the zero-product property:
\((n-6)=0 \implies n=6\)
\((2n+17)=0 \implies n=-8.5\)
n = -8.5 is an extraneous solution since this solution gives negative side lengths, which is impossible.
Therefore, the only valid value of n is n = 6.
\(\hrulefill\)
Check by substituting the found value of n:
\(\textsf{Width}=6+4=10\; \sf cm\)
\(\textsf{Length}=2(6)-3=9\; \sf cm\)
\(\textsf{Area}=10 \cdot 9=90\; \sf cm^2\)

I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

Answer: Slopes are not equal so the function is not linear
Step-by-step explanation:
Slope is change in y/ change in x = y2-y1/ x2-x1
Calculations for (-1, -4) and (0, -3)
slope = -3- -4/0- -1 = 1/1 = 1
Next Calculate the slope between (0,-3) and (2,5)
slope = 5--3/2-0 =8/2=4
Slopes are not equal so the the points are not linear

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.
