The graphs below have the same shape. What is the equation of the blue graph? G(x) =
A. G(x)= (x+4)^2
B.G(x)=x^2+4
C.G(x)= (x-4)^2
D.G(x)= x^2-4
Answer:
CStep-by-step explanation:
G(x) is transformed from the parent function f(x)=x^2 by:
right 4 units
since we all know that the vertex form of a quadratic equation is y=a(x-h)^2+k
since 4 is h, and k is 0 ( graph is on the x-axis), we can write the equation of this graph:
g(x)=(x-4)^2, which is C

I’m confused :( I will mark as Brainliest and give you points
Answer:
123.5 square inches
Step-by-step explanation:
Given: To find the area of a rectangle, you have to multiply base times height.
To find the area of a triangle, you have to do base times height devided by 2.
Finding the area: Let's break up this shape into polygons. At the bottom there is a rectangle. We know that to find the area of the rectangle you have to do base times height. 13in•7in will give you 91in square for the rectangle.
Now for the triangle. If you can see, if you break the triangle in half, there are 2 right triangles. Let's look at the right one for now. Since we know that to find the area of a triangle you have to do base times height divided by 2, you do 5in•6.5in=32.5in. 32.5in divided by 2 is 16.25in square which is the area of one triangle. You might be wondering why i did 5•6.5, and that's because at the bottom of the rectangle you can see it's 13in, and 13in÷2=6.5in.
We already found the area of the rectangle and one triangle. The other triangle is equal to it so we can just do 16.25+16.25=32.5in square for both of the triangles.
Now we add it all up: 32.5+91=123.5 square inches
The solution of the equation 5 - 2x = -4x – 7 is
1.
1
2.
2
3.
-2
A
-6
Answer:
x = -6.
Step-by-step explanation:
5 -2x = -4x - 7
Add '4x' to both sides:
5 - 2x + 4x + -4x + 4x -7
5 + 2x = -7
Subtract '5' from both sides:
5 - 5 + 2x = -7 - 5
2x = -12
Divide both sides by '2':
x = -6.

which graph best represents the solution to 1/2 x -2 = 3?
Answer:
i believe the answer is D (which is 10)
Step-by-step explanation:
i just took the test. so you have to isolate X, so you add 2 to both sides and on the right you get answer of "5". so then you have to multiply both sides by "2/1" (which is the reciprocal of 1/2) and so on the left side so you're left with just "x", and on the right side you have 2/1 times 5/1 which equals "10".

Given: Isosceles triangle ABC with vertex angle A, equal sides AB and AC, and an angle bisector, BD.
side = 1
angle = 36
BC has a length of 1. To the nearest tenth of a unit, find the lengths of the missing sides.
BD = __ units
AD = __ units
AB = __ units
AC = __ units
Answer:
BD = 1 unit
AD = 1 unit
AB = 1.6 units
AC = 1.6 units
Step-by-step explanation:
In the picture attached, the triangle ABC is shown.
Given that triangle ABC is isosceles, then ∠B = ∠C
∠A + ∠B + ∠C = 180°
36° + 2∠B = 180°
∠B = (180° - 36°)/2
∠B = ∠C = 72°
From Law of Sines:
sin(∠A)/BC = sin(∠B)/AC = sin(∠C)/AB
(Remember that BC is 1 unit long)
AB = AC = sin(72°)/sin(36°) = 1.6
In triangle ABD, ∠B = 72°/2 = 36°, then:
∠A + ∠B + ∠D = 180°
36° + 36° + ∠D = 180°
∠D = 180° - 36° - 36° = 108°
From Law of Sines:
sin(∠A)/BD = sin(∠B)/AD = sin(∠D)/AB
(now ∠A = ∠B)
BD = AD = sin(∠A)*AB/sin(∠D)
BD = AD = sin(36°)*1.6/sin(108°) = 1
Drag the tiles to the correct boxes to complete the pairs. Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle.
Answer:
[tex]tanC=\frac{c}{b},[/tex] [tex]sinB=\frac{b}{a},[/tex] [tex]tanB=\frac{b}{c},[/tex] and [tex]cosB =\frac{c}{a}[/tex]
Step-by-step explanation:
We can use the phrase SOH-CAH-TOA to help us with this problem. SOH-CAH-TOA stands for Sine = Opposite / Hypotenuse, Cosine = Adjacent / Hypotenuse, and Tangent = Opposite / Adjacent. This phrase helps to remember which sides of a right triangle get divided by which.
First, we'll evaluate [tex]cosB[/tex]. Referencing CAH (Cosine = Adjacent / Hypotenuse), we know that [tex]cosB[/tex] is equal to the length of the adjacent leg to ∠B, which is c, divided by the length of the hypotenuse of the right triangle, which is a. Therefore, [tex]cosB =\frac{c}{a}[/tex].
As for [tex]tanC[/tex], we can refer to TOA (Tangent = Opposite / Adjacent), which means that [tex]tanC[/tex] is equal to the length of the opposite leg to ∠C, which is c, divided by the length of the adjacent leg to ∠C, which is b. Therefore, [tex]tanC=\frac{c}{b}[/tex].
As for [tex]sinB[/tex], we can refer to SOH (Sine = Opposite / Hypotenuse), which means that [tex]sinB[/tex] is equal to the length of the opposite leg to ∠B, which is b, divided by the length of the hypotenuse of the right triangle, which is a. Therefore, [tex]sinB=\frac{b}{a}[/tex].
Finally, we'll evaluate [tex]tanB[/tex]. As TOA tells us, [tex]tanB[/tex] is equal to the length of the opposite leg to ∠B, which is b, divided by the adjacent leg to ∠B, which is c. Therefore, [tex]tanB=\frac{b}{c}[/tex].

Answer:
27.5
Step-by-step explanation:
this is the trigonometric ratio.. we are looking for d... that is the opposite... any side facing the angel is the opposite.... so the longest side of the right angle triangle is the hypotenuse........ so you are looking for the opposite and you are giving the hypotenuse.... so the easiest way to know how to find it is by using this way...... SOH CAH TOA..... the first words stand for sin cosine and tangent of angles.... we are using sin.... because it says opposite / hypotenuse... and as you can see the angle which is 39 degree we will use sin 39.....what will be sin 39=d/30m....then ull cross multiply.... d=30m* sin 39.....
d = 30m *0.963
d = 28.8

Jack's credit card has a 20% APR. Find the periodic interest rate from June 3
to July 2. Round your answer to two decimal places,
O A. 2.35%
O B. 1.67%
O c. 2.12%
O D. 1.64%
Answer:
B. 1.67%
Step-by-step explanation:
The periodic rate is the annual interest rate divided by the number of periods.
The period from June 3 to July 2 is a Month.There are 12 Months in a YearTherefore, we divide the annual interest rate by 12.
[tex]20\% \div 12 =1.67\% $(correct to two decimal places)[/tex]
Therefore, the periodic interest rate for Jack's credit card from June 3
to July 2 is 1.67%.

Bob and Sally's mortgage payment increases to $1632.00. Their roof starts to leak and they need to replace it. They budget $500 per month (replace the old student loan charge with roof expense).
Answer:
List of expenses is attached below.
Total Income = $160 + $6245 = $6405
1) Do Bob and Sally have a surplus or deficit?As mortgage payment has increased, we replace $1580 with $1632 in the table
Replace student loans with roof expense, we replace $544 with $500 in the table.
Find Total Expenses by adding all the values from the table.
Total Expenses = $6660.17
Total Income =$6405
They have a deficit
2) By how much?Deficit = $6660.17 - $6405 = $255.17
Deficit = $255.17
3) They decide to stop putting money in savings. How much their balance be?Savings = 10% of income = 10% OF $6405
Savings = (10/100)· $6405 = $640.5
New total expenses = $6660.17 - $640.5
New total expenses = $6019.67
Balance = Total income - New total expenses = $6405 - $6019.67
Balance = $295.33
4) Do you agree with them removing the savings to create surplus?
Yes, they had to remove the savings to fulfill their expenditures. Otherwise, they would have been spending more than their income, which couldn't last very long
