Answer:
Below in bold.
Step-by-step explanation:
m < C = 180 - 43 - 115 = 22 degrees.
Using the Sine Rule:
6 / sin 22 = a / sin 43
a sin 22 = 6 sin 43
a = 6 sin 43 / sin 22
a = 10.92 to 2 DP's.
Applying the same rule to calculate b:
6 / sin 22 = b / sin 115
b = 6 sin 115 / sin 22
b = 14.52 to 2 DP's.

check whether x² +4x +4 is prefect spuare expression or not . if so factorise the expression
Answer:
It is a perfect square expression.
It factors to (x+2)^2
===========================================================
Explanation:
The general format for a perfect square is
(a+b)^2 = a^2 + 2ab + b^2
Which can be seen through the use of the FOIL rule.
Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:
x^2 = a^2 .... first terms4x = 2ab .... middle terms4 = b^2 .... last termsSince x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.
Because a = x and b = 2, we then can say:
(a+b)^2 = a^2 + 2ab + b^2
(x+2)^2 = x^2 + 2*x*2 + 2^2
(x+2)^2 = x^2 + 4x + 4
Showing that x^2+4x+4 factors to (x+2)^2.

What is Trigonometry?One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.
As per the given data:
x = 41 cm
v = 17 cm
∠W = 134°
To find the length of w:
From the cosine law: [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]
[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]
Hence, the length of w is 54 cm.

Belinda has a savings account. Every month she deposits $30 in it. The graph shows the relationship between the months and the balance of Belinda's savings account.
Write an inequality to show when Belinda will have more than $120 in her savings account.
Answer:
Lets say that m is months
Every month she deposits 30 so that is 30m
lets say t is time
t = 30m > 120
After 4 months, she will have exactly $120. In 5, she will have more.
Step-by-step explanation:
log2 (X^2+3x+2)=1 state the universe and solve each of the following for x.
By "state the universe" I suppose you mean "domain". log₂(x ² + 3x + 2) is defined for
x ² + 3x + 2 = (x + 1) (x + 2) > 0 → x < -2 or x > -1
(To solve the inequality, consider values of x between the ones that make the expression exactly equal to 0, in this case x = -2 and x = -1. We have, for instance, for x = -3, that (-3)² + 3(-3) + 2 = 2 > 0, so x ² + 3x + 2 > 0 for all x < -2.)
Now solve the equation: Write both sides as powers of 2 to eliminate the logarithm on the left:
[tex]\log_2(x^2+3x+2)=1\implies 2^{\log_2(x^2+3x+2)}=2^1\implies x^2+3x+2=2[/tex]
Solve the remaining quadratic:
x ² + 3x + 2 = 2
x ² + 3x = 0
x (x + 3) = 0
x = 0 or x = -3
Both of these solutions are within the presribed domain (-3 < -2 and 0 > -1), so we're done.

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
9514 1404 393
Answer:
90°
Step-by-step explanation:
The largest angle is 6 of the 6+1+5 = 12 ratio units, so is 6/12 = 1/2 of the total number of degrees in a triangle.
The largest angle is 1/2(180°) = 90°.

I bought four bags of cotton candy for $1.50 each and two soft drinks for 90 cents each. What was my change from a ten dollar bill
Answer:
Your change is $2.20
Step-by-step explanation:
4 x $1.50 = $6
2 x $.90 = $1.80
$6 + $1.80 = $7.80
$10 - $7.80 = $2.20
So it's $2.20. Have a nice day :D
Answer:
$2.20
Step-by-step explanation:
4 bags of cotton candy
$1.50 x 4 = $6.00
2 soft drinks
$0.90 x 2 = $1.80
$6.00 + $1.80 = $7.80
$10.00 - $7.80 = $2.20

Answer: 11
Step-by-step explanation:
When you do square root, you're just finding the number that can be multiplied by itself to get what's inside the √ .
So, when you do √121 , you'll get 11. You can check your answer by going backwards: multiply 11 by itself.

Let the function f(x) have the form f(x) = Acos(x-C). To produce a graph that matches the one shown below, what must the value of C be?
Answer: Option B, C = 3.
Step-by-step explanation:
Here we have the function:
f(x) = A*cos(x - C)
A is the amplitude, and we can easily see that the amplitude is 2.
Then:
f(x) = 2*cos(x - C)
We also can see that when x = 0, f(x) ≈ -2
This means that:
cos(0 - C) ≈ -1
Cos(C) ≈ -1
Now we can just evaluate in the different options and see which one is the correct option.
Cos(1) = 0.54
Cos(2) = -0.42
Cos(3) = -0.99
Cos(4) = -0.65
The closer option to -1 is when C = 3, then the correct option is option B.
Answer:
B

What is the slope of the line through the points (-2, -1) and (4, 3)?
1. 3/2
2. 5/2
3. 2/5
4. 2/3
Answer:
4. 2/3
Step-by-step explanation:
Plug the coordinates into the formula.
y2 - y1 / x2 - x1
= 3 - (-1) / 4 - (-2)
= 2/3
Write the equation of each line in slope-intercept form and identify the slope. 4x=2+y
Answer:
y = 4x - 2
Step-by-step explanation:
Given: 4x=2+y
First, subtract 2 on both sides to isolate out y. (Slope-intercept form is y=mx+b)
Once subtracted, you get: 4x-2=y
Rearrange it, and you get: y=4x-2
