Answer:
Step-by-step explanation:
21 is the side opposite the angle you want.
67 is the hypotenuse. Those two sides define the Sin
Sin(theta) = opposite / hypotenuse
Sin(theta) = 21 / 67
Sin(theta) = .313432
theta or x = sin-1(0.313432)
x = 18.27
Sorry, I must have hit the wrong key the first time.
Answer:
18.27˚

(b) factorise
(3m-1)(6-a)-(m+3)(6-a)
Answer:
Step-by-step explanation:
(3m-1)(6-a)-(m+3)(6-a)
=3m(6-a)-1(6-a)-m(6-a)+3(6-a)
=18m-3ma-6+a-6m+ma+18-3a
=12m-2ma+12-2a
=2(6m-ma+6-a)
Function g can be thought of as a scaled version of f(x)=x^2
Write the equation for g(x)
A scaled version means that our leading coefficient will change. Let's set up an equation to find our leading coefficient, a.
g(x) = a * x^2
Now that we have our equation, we need a point that is on g(x). The point given is (4,8). Let's use that point and plug x and y into our equation so that we can solve for a.
8 = a * (4)^2
8 = a * 16
a = 1/2
All that's left to do is plug in our a value into g(x).
g(x) = 1/2 x^2

Q1)What is the sum of the finite arithmetic series −10, −8, −6, −4, ...24?
show work !!
Q2)You are trying to save $1500. You begin with $5 and save $3 more than the previous amount each week for 30 weeks. Will you meet your goal? Explain. Show work
Solution :
First term, a₀ = -10 .
Common difference of A.P. , d = -8 - (-10) = 2 .
Last term, aₙ = 24 .
We know, last term is given by :
aₙ = a₀ + (n-1)d
24 = -10 + (n-1)×2
2n - 2 = 34
n = 18
Now, sum of series is given by :
[tex]S_n = \dfrac{n}{2} \times ( 2a+(n-1)d)\\\\S_n = \dfrac{18}{2} \times ( 2\times -10 + ( 18 -1) \times 2)\\\\S_n = 126[/tex]
Hence, this is the required solution.

On Sunday Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg of plant food on his strawberry plants and used 1/4 kg of plant food on his tomato plants.
Answer:
27/12 KG
Step-by-step explanation:
On Sunday, Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plants. How many kilograms of plant food did Sheldon have left?
41/2 - (12/3 + 1/4)
[tex]1\frac{2}{3} + \frac{1}{4}[/tex]
[tex]1\frac{8 + 3}{12}[/tex] = 1 11/12

HELPPPPP ANSWER GETS BRAINLIEST
Answer:
56 degrees
Step-by-step explanation:
If you look at the m<KLN you can see that it is an acute angle. So, with this being said you have to know that the measure KLN is going to be less than 90 degrees. So you would subtract 180 and 124 and you would get 56 degrees.

Which graph best represents the solution to the following pair of equations?
y = 4x + 2
y = x + 5
Answer:
The first picture with the (1,6)
Step-by-step explanation:
If you plug in the numbers in the equations you will see that they both equal 6.
6=4(1)+2
6=4+2
6=6
6= (1)+5
6=6
Find the length of the hypotenuse
Answer: The answer is “10cm”
Step-by-step explanation: To get to this answer we first need to know the formula for find the hypotenuse which is a^2 + b^2 = c^2. A and B are the two sides in this case a and b are 8 cm and 6 cm. Then you plug in the values into the equation, it looks like this 8^2 + 6^ = c^2 once you solve you get 64 + 36 = c. When you add 64 and 36 you get 100 but their is one more step. You must find the square root of 100 which is 10. So your answer for the hypotenuse is “10cm”

Find tanθ + sinθ for the angle below.
tan( tehta ) = 2/3
Sin( tetha ) = 2/√13
tan( tetha ) + Sin( tetha ) = 2/3 + 2/√13
= 2√13 + 6 / 3√13
Susan wants to hire one of two mechanics to repair her car. Each mechanic charges a one-time fee in
addition to an hourly rate.
Mechanic A charges a one-time fee plus $35 per hour. A repair made by Mechanic A that takes 5 hours to
complete will cost a total of $225.
This table shows the total cost, including the one-time fee, for repairs made by Mechanic B that take
different numbers of hours to complete
Mechanic B

How much more money in dollars does Mechanic A charge for the one-time fee than Mechanic B
charges?
there no table showing mechanic b. but mechanic a charges a one time fee of $50
35 an hour times 5 hours is 175
the total of 225 -175= $50 as a one time fee
