Answer:
Step-by-step explanation:
there are 2 ways to graph equations. I'll teach u the faster way.
step 1) graph the y-intercept.
so the slop-intercept form of a line is y=mx+b. b represents the y-intercept and m represents the slope. u need two points to graph a line, the first point will be the y intercept. in this case, the y-intercept is -5. so this is what you should do: (the underlined star represents a point. also, the underlined star is on point -5.)
| y
|
|
|
------------------------------------------------------------x
|
|
|
|
*
|
step 2) graph the second point using the slope.
slope equals rise over run. (m=rise/run.) in this case, the slope is 5/1. To graph the second point, u should RISE up by 5 and RUN to the right by one: (the underlined star is on point 1.)
| y
|
|
|
-----------------------*-------------------------------------x
|
|
|
|

now draw a line through those two points.

THE ROOM NUMBER OF THE TWO ADJACENT CLASSROOMS ARE TWO CONSECUTIVE ODD NUMBERS IF THE SUM IS 216FIND THE CLASSROOM NUMBERS
Answer:
Step-by-step explanation:
To make sure that you are adding 2 odd numbers, the first one is 2x - 1 and 2x + 1
Their sum is 216
Equation
2x - 1 + 2x + 1 = 216
Solution
2x - 1 + 2x + 1 = 216 Combine like terms on the left
4x = 216 Divide by 4
4x/4 = 216/4 Combine
x = 54
Answer
2x - 1 = 2*54 - 1 = 108 - 1 = 107
2x + 1 = 2*54 + 1 = 108+1 = 109
The two consecutive odd numbers are 107 and 109
5 1/10 x 1/6 pls helppp
Answer:
51/60
Step-by-step explanation:
First, I'll convert 5 1/10 into an improper fraction to make it easier to work with. I get 51/10. Then, I multiply the two fractions like so:
51/10 * 1/6 = 51/60
You multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately.
So the answer is 51/60.

Answer: x=120 degrees
Step-by-step explanation: Since this triangle is equilateral, each of its angles equals 60 degrees. The line that x is on is equal to 180 degrees, so subtracting 60 from 180 will give you 120 degrees for x.
Answer:
x=180°-60°=120°, bc In an equilateral triangle, the angles are equal and equal to 60°

Use either direct or synthetic substitution to evaluate the
following:
f(x)=2x3-2x2+2x-8 for f(1).
Points A and B are 100m apart on a coastline.
B is directly east of A.
A lighthouse is out at sea.
The bearing of the lighthouse is
164 degrees from A and
217 degrees from B
The angle of elevation of the top of the lighthouse from A is 27 degrees.
Find the distance of the lighthouse from A.
Find the height of the lighthouse.
Points A, B and the lighthouse are related by angles of elevation.
The distance of the lighthouse from A is 97.4 mThe height of the lighthouse is 79.9 mFrom the complete question (see attachment), we have:
[tex]\mathbf{\angle A = 164 - 90}[/tex]
[tex]\mathbf{\angle A = 74}[/tex]
[tex]\mathbf{\angle B = 270 - 218}[/tex]
[tex]\mathbf{\angle B = 52}[/tex]
[tex]\mathbf{\angle L = 180 - 74 - 52}[/tex]
[tex]\mathbf{\angle L = 54}[/tex]
(a) The distance between the lighthouse and A
This is calculated using the following sine ratio
[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]
So, we have:
[tex]\mathbf{\frac{AL}{sin B} = \frac{100}{sin L}}[/tex]
This gives
[tex]\mathbf{\frac{AL}{sin 52} = \frac{100}{sin 54}}[/tex]
Make AL the subject
[tex]\mathbf{AL = \frac{100}{sin 54} \times sin 52}[/tex]
[tex]\mathbf{AL = 97.4}[/tex]
The distance of the lighthouse from A is 97.4 m
(b) The height of the lighthouse
Considering triangle AHL, we have:
[tex]\mathbf{\angle H = 90 + 27 = 117}[/tex]
[tex]\mathbf{\angle A = 74 - 27 = 47}[/tex]
[tex]\mathbf{AL = 97.4}[/tex]
The height is then calculated using the following sine ratio
[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]
So, we have:
[tex]\mathbf{\frac{AL}{sin H} = \frac{HL}{sin A}}[/tex]
Make HL the subject
[tex]\mathbf{HL = \frac{AL \times sin A}{sin H}}[/tex]
This gives
[tex]\mathbf{HL = \frac{97.4 \times sin 47}{sin 117}}[/tex]
[tex]\mathbf{HL = 79.9}}[/tex]
Hence, the height of the lighthouse is 79.9 m

20 points (looking for the reasoning) Jayden and Sheridan both tried to find the missing side of the right triangle.
A right triangle is shown. One leg is labeled as 7 centimeters. The hypotenuse is labeled as 13 centimeters.
Jayden's Work Sheridan's Work
a2 + b2 = c2 a2 + b2 = c2
72 + 132 = c2 72 + b2 = 132
49 + 169 = c2 49 + b2 = 169
218 = c2 b2 = 120
Square root 218 equals square root c squared. Square root b squared equals square root 120.
14.76 ≈ c b ≈ 10.95
Is either of them correct? Explain your reasoning.
Answer:
Step-by-step explanation:The problem is very hard to read. When using exponents, please add the "^" in front. For example, is 132 actually 132, or is it 13^2? The right triangle is not shown, so we really don't know which is the hypotenuse. Also be carefull with spacing. Making some assumptions, here is how the answer might look:
Both have the correct formula: a^2 + b^2 = c^2, assuming c is the hypotenuse.
If c is the hypotenuse, then the expression should be:
7^2 + b^2 = 13^2, or
49 + b^2 = 169
I like Sheridan's answer. So let's continue:
49 + b^2 = 169
b^2 = 169-49
b^2 = 120
b = 10.954 . . .
Yep, I'm on Sheridan's side. [That is, unless 72 is 72 and not 7^2, etc.]

Graph the function h (x) = -3x-1.
I'm trying to find the explicit form of an equation after performing an integration. I'm a bit rusty.
ln|y| = C - cos(x)
C is an arbitrary constant.
Is it:
y = e^(c-cos(x))
or because it's an arbitrary constant, can it be written:
y = C - e^(cos(x))
Thanks.
No, it should be written as
[tex]y = Ce^{-\cos x}[/tex]
Provided that y ≠ 0, both solutions
[tex]y = e^{C-\cos(x)}[/tex]
and
[tex]y = Ce^{-\cos(x)}[/tex]
are correct. The other solution you provided,
[tex]y = C - e^{\cos(x)}[/tex]
is not.
The only difference between the "valid" solutions lies in the particular value of the arbitrary constant C.
Suppose y(0) = Y ≠ 0 is given as an initial condition. Then in the first solution,
[tex]Y = e^{C - \cos(0)} \implies \ln|Y| = C - 1 \implies C = \ln|Y| + 1[/tex]
In the second solution,
[tex]Y = C e^{-\cos(0)} \implies Y = Ce^{-1} \implies C = eY[/tex]
But both solutions are the same, since
[tex]y = e^{\ln|Y| + 1 - \cos(x)} = e^{\ln|Y|} e^1 e^{-\cos(x)} = eY e^{-\cos(x)}[/tex]
$5400 at 3.6% compounded continuously for 5 years.
Answer:
A = $6,464.97
Step-by-step explanation:
Given the principal amount of $5,400, and an interest rate of 3.6% compounded continuously for t = 5 years:
Substitute the given values into the Continuous Compounding Formula:
[tex]A = Pe^{r*t}[/tex]
where:
P = principal = $5,400
e ≈ 2.7183 (irrational number)
r = interest rate = 3.6% or 0.036
t = time in years = 5
[tex]A = Pe^{r*t}[/tex]
[tex]A = 5400e^{(0.036*5)}[/tex]
[tex]A = 5400e^{0.18}[/tex]
A = $6,464.97
Therefore, the amount after compounding continuously for 5 years is $6,464.97.

Answer:
-2 3/5, -9/4, 1.2, 7/4
Step-by-step explanation:
First, unmix the mixed numbers.
-9/4 = -2 1/4.
Which is greater?
1/4 vs. 3/5
Answer: 3/5 So...
-2 3/5 would be the least.
Then there would be -2 1/4
Then, it would be 1.2 because 1.2 is smaller than 7/4.
Therefore, this pattern would be the correct answer...
From Least to greatest=
-2 3/5, -9/4, 1.2, 7/4

ron goes to a shop to buy some notebooks. the shopkeepers informs him that 2 notebooks would cost $90. can you find the cost of 5 notebooks with the help of unitary method
Answer: $225
Step-by-step explanation:
Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2
Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

Answer:
$225 = 5 note books.
45 = 1 note book
Step-by-step explanation:

Unitary method means find 1 part first.
Therefore,
1 part = 45
45 x 5 = 225
$225 = 5 note books.
