Which graph shows a set of ordered pairs that represent a function?
Need help
Answer:
The third graph, the top right graph
Step-by-step explanation:
A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function. If 1 x value is equal to 2 y values, it is not a function.
Given that cot θ = 1/√5, what is the value of (sec²θ - cosec²θ)/(sec²θ + cosec²θ) ?
(a) 2/3
(b) 3/2
(c) 25/36
(d) 12/13
Step-by-step explanation:
[tex]\mathsf{Given :\;\dfrac{{sec}^2\theta - co{sec}^2\theta}{{sec}^2\theta + co{sec}^2\theta}}[/tex]
[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{{sec}\theta = \dfrac{1}{cos\theta}}}}[/tex]
[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{co{sec}\theta = \dfrac{1}{sin\theta}}}}[/tex]
[tex]\mathsf{\implies \dfrac{\dfrac{1}{cos^2\theta} - \dfrac{1}{sin^2\theta}}{\dfrac{1}{cos^2\theta} + \dfrac{1}{sin^2\theta}}}[/tex]
[tex]\mathsf{\implies \dfrac{\dfrac{sin^2\theta - cos^2\theta}{sin^2\theta.cos^2\theta}}{\dfrac{sin^2\theta + cos^2\theta}{sin^2\theta.cos^2\theta}}}[/tex]
[tex]\mathsf{\implies \dfrac{sin^2\theta - cos^2\theta}{sin^2\theta + cos^2\theta}}[/tex]
Taking sin²θ common in both numerator & denominator, We get :
[tex]\mathsf{\implies \dfrac{sin^2\theta\left(1 - \dfrac{cos^2\theta}{sin^2\theta}\right)}{sin^2\theta\left(1 + \dfrac{cos^2\theta}{sin^2\theta}\right)}}[/tex]
[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{cot\theta = \dfrac{cos\theta}{sin\theta}}}}[/tex]
[tex]\mathsf{\implies \dfrac{1 -cot^2\theta}{1 + cot^2\theta}}[/tex]
[tex]\mathsf{Given :\;cot\theta = \dfrac{1}{\sqrt{5}}}[/tex]
[tex]\mathsf{\implies \dfrac{1 - \left(\dfrac{1}{\sqrt{5}}\right)^2}{1 + \left(\dfrac{1}{\sqrt{5}}\right)^2}}[/tex]
[tex]\mathsf{\implies \dfrac{1 - \dfrac{1}{5}}{1 + \dfrac{1}{5}}}[/tex]
[tex]\mathsf{\implies \dfrac{\dfrac{5 - 1}{5}}{\dfrac{5 + 1}{5}}}[/tex]
[tex]\mathsf{\implies \dfrac{5 - 1}{5 + 1}}[/tex]
[tex]\mathsf{\implies \dfrac{4}{6}}[/tex]
[tex]\mathsf{\implies \dfrac{2}{3}}[/tex]
Hence, option (a) 2/3 is your correct answer.

A store decides on the cost of a pair of jeans by tripling their cost and then decreasing it by $15. The cost of the jeans in the store is $105. What does the store pay for the jeans?
Answer:
40$
Step-by-step explanation:
if we write it out in an equation, we get
105(final price) = 3x (triple the value they produce it for) - 15 (they degrease it by 15)
subtract 15 from both sides, you get 120 = 3x
divide both sides by 3, you get 40 = x

how many do 942 units cost?
the answer is not 13,188 because it says it's wrong for me.
Answer:
67.28
Step-by-step explanation:
uh I'm kinda unsure but I think you could try isolating the variable? so you could try 942 ÷ 14 = 67.28? just a guess, tell me if it works out!
1. Write the equation in slope intercept form that represents the line that passes through (-4, -3) and (-2, 1)?
Answer:
y = 2x + 5
Step-by-step explanation:
Finding the slope:
[tex]\frac{y2-y1}{x2-x1}\\[/tex]
= (1-(-3))/(-2-(-4))
= (1+3)/(-2+4)
= 4/2
= 2
Slope: 2
Substituting the slope into the formula 'y=mx+c':
y = 2x+c
Substituting any point (in this case, (-2,1)):
1 = 2(-2) + c
1 = -4 + c
c = 1 + 4
c = 5
Hence,
y = 2x + 5

Which expression is equivalent to13 p + 15? Btw happy almost halloween
Answer:
13
Step-by-step explanation:
13p + 15
The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of [tex]ax^{n}[/tex] is [tex]nax^{n} ^{-1}[/tex]
[tex]13p^{1-1}[/tex]
subtract 1 from 1
[tex]13p^{0}[/tex]
For any term t except 0, [tex]t^{0}[/tex] = 1
13 × 1
For ant term t, t × 1 = t and 1t = t

128 in exponential form
Answer:
2^12
Step-by-step explanation:
I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,
128 x 32 = 2^5 x 2^7.
The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:
2^5 x 2^7 = 2^5+7= 2^12.
And that is in exponential form. So the final answer is
128 x 32 = 2^12
Answer:
[tex]128 \: \: is \: \: 32 \times 4, \\ \\ so 128 is {2}^{5} \times 2 \times 2 = {2}^{7} . \\ \\ Thus, 128 \times 32 = {2}^{5} \times {2}^{7} .[/tex]
Help will mark brainliest to best answer
Answer:
Im not sure but probably its B
Answer:
I believe the answer is A. This is because 15 less than a would be a-15, and since it's asking for the quotient of 15 less than a and 10, it would be a-15/10.

Answer:
1. D.
2. B.
Step-by-step explanation:
1. D. None of the above.
If the three angles of one triangle are congruent to the three angles of another triangle, the triangles are similar, but there is not enough information to prove they are congruent.
2.
The given information gives us a side and an adjacent angle of each triangle.
Since all choices involve sides, we need another pair of sides to use SAS. The angle must be included by the two sides.
We need sides DF and JH to be congruent.
By knowing that DH is congruent to JF, you add HF to both segments giving DF congruent to JH, and the triangles are congruent by SAS.
Answer: B.

Exercise #6: Demarco is trying to determine how many pennies he has without having to count
them. He first weighs 20 pennies and finds they have a total weight of 54 grams. He then weighs
all the pennies and finds they weigh a total of 918 grams.
(a) Determine how much a single penny
weighs, i.e. the grams per penny.
(b) Use your answer from (a) to determine
how many pennies Demarco has.
Step-by-step explanation:
20 pennies weigh 54 grams.
what is the weight of a single penny ?
well, 1/20 of the weight of the 20 pennies.
so,
54/20 = 27/10 = 2.7 grams
all his pennies weigh 918 grams.
how many pennies are there ?
as many as the times the weight of a single penny fit into the total weight.
so,
918 / 2.7 = 9180/27 = 340
he has 340 pennies.
