Find X and angles R and L. Please help me with this
4. If f(x)=2x+3(x+4)+5 then f(6)=?
Answer:
f(6)=42
Step-by-step explanation:
We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.

Answer: 47
Step-by-step explanation:
That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.
Garrett throws a dart at a circular dart board. The dart board has a radius of 16 inches, and the bull's eye in the center of the dart board has a radius of 6 inches
What is the probability that a dart thrown at random within the dartboard will hit the bull's eye? Round your answer to the nearest tenth, if necessary
A. 37.5%
B. 26.7%
C. 7.1%
D. 14.1%
Answer:
C. 7.1
Step-by-step explanation:
Answer:
The probability that a dart thrown at random within the dartboard will hit the bull's eye is 14.1%
Step-by-step explanation:
[tex]The probability is found by dividing the area of the bull's eye by the total area of the dart board:\[\large P(bull's\ eye)=\frac{\pi\ 6^{2}}{\pi\ 16^{2}}=\frac{36}{256}=0.1406\]Therefore your answer of 14.1% is close.[/tex]

solve the equation for x
2/3x-1/9x+5=20
Answer:
x=27
Step-by-step explanation:
You want to isolate the variables so you subtract 5 from both sides. Therefore the equation will be 2/3x-1/9x=15. You want to take away the fraction because no one likes fractions. You have to multiply everything by 9. Therefore, the equation will be 6x-x=135. 5x=135. You want to isolate x so you have to divide each side by 5. x=135/5. Simplify to get x=27.

A millennium is a period of 1,000 years.
So, 4,000 years is 4 millennia.
How many millennia are there in 5,000 years?
Answer:
5 millennia
Step-by-step explanation:
The simplest way to get the answer is that a millennium is 1,000 years and since you mentioned there are 4 millennia in 4,000 years, you would need to divide 5,000 by 1,000. Your answer should be 5 millennia.
Given circle Q a measure of SR = 120 degree and a radius of 9 feet, as shown below determine the arc length of SR use mathematics to explain how you determined your answer. 
Volume and circles
Help please ❤️
Answer:
Arc length SR = 18.85 ft
Step-by-step explanation:
To get the arc length, we use the formula below
theta/360 * 2 * pi * r
theta is the central angle subtended by the arc which is 120 degrees
r is the radius of the circle which is 9 ft
Substituting these values, we have
120/360 * 2 * 3.142 * 9
= 18.85 ft

A sundae bar has five toppings to choose from. Any number of toppings can be
chosen. How many different sundaes are possible?
Answer: 32
Step-by-step explanation:
When given a question where there is a distinct set of items to choose from, the total number of configurations is equal to 2 to the power of number of different choices. Since there are five different choices, the number of different sundaes is equal to 2^5 or 32 sundaes.
The following tables show some values from three different functions. which of these functions could be quadratic?
Answer:
C. III only
Step-by-step explanation:
a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.
so, let's look at the tables.
table I shows the powers of 2. y = 2^x
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
so, it is not saying anything in general.
table II shows an "identity" equation. y = x
0 = 0
1 = 1
2 = 2
3 = 3
this does not square anything.
table III shows then finally a square equation. y = x^2
0^2 = 0
1^2 = 1
2^2 ≈ 4
3^2 = 9

Find the measure of \angle RST∠RST. The measure of \angle RST∠RST is ^{\circ} ∘ .
Answer:
[tex]RST =144[/tex]
Step-by-step explanation:
Given

Required
Find RST
To do this, we use:
[tex]RST + 36 = 180[/tex] --- angle on a straight line
Make RST the subject
[tex]RST =- 36 + 180[/tex]
[tex]RST =144[/tex]
Hence, the measure of RST is 144
Line m is represented by the equation below. Select all equation that represent lines perpendicular to line m.
Answer:
y = -2/3x + 4
y+1 = -4/6(x + 5)
Step-by-step explanation:
y = -2/3x + 4
y+1 = -4/6(x + 5) *-4/6 is equal to -2/3
perpendicular lines have slope that are opposite signs and reciprocals
the slope of the original line in this problem is 3/2 so any line with a slope of -2/3 is perpendicular to it
Answer:
it will be any equation with a slope that is the opposite reciprocal of 3/2 or it's equivalent. So in this case, -2/3. be sure to check the negative does and see if other slopes are the same as -2/3 but in a different form.

Solve the right triangle.
Round your answers to the nearest tenth.
Answer:
A = 43°
b = 26.8
c = 36.7
Step-by-step explanation:
✔️Find A:
A + 90° + 47° = 180° (sum of triangle theorem)
A + 137° = 180°
Subtract 137° from each side
A = 180° - 137°
A = 43°
✔️Find b and c by applying trig functions:
Reference angle = 47°
Opposite = b
Hypotenuse = c
Adjacent = 25
To find b, apply TOA:
Tan 47° = Opp/Hyp
Tan 47 = b/25
25*Tan 47 = b
26.8092178 = b
b = 26.8 (nearest tenth)
To find c, apply CAH:
Cos 47° = Adj/Hyp
Cos 47° = 25/c
c*Cos 47° = 25
c = 25/Cos 47°
c = 36.6569796
c = 36.7 (nearest tenth)

Answer:
(7, 4)
Step-by-step explanation:
The solution to the system of the 2 equations represented on the graph by the two lines is the c
x and y coordinates of the point where the two lines intersect.
They intersect at when x = 7, y = 4.
Therefore, the solution to the system of equations would be (7, 4).
