Let f(x) = 5x + 4 and g(x) = −2x + 1. Find the indicated value f(6)+g(-8) plz help quickly
Answer:
The answer is 51
Step-by-step explanation:
f(x) = 5x + 4
g(x) = −2x + 1
To find f(6)+g(-8) first find f(6) and g(-8) and add them
For f(6) we have
f(6) = 5(6) + 4
= 30 + 4
= 34
For g(-8)
g(-8) = - 2(-8) + 1
= 16 + 1
= 17
So we have
f(6)+g(-8) is
34 + 17
= 51

Which expression is equivalent to the area of square A, in square inches?
Answer:
10² + 24²
Step-by-step explanation:
The diagram illustrates Pythagoras' identity.
The square on the hypotenuse of a right triangle is equal t o the sum of the squares on the other 2 sides.
A is the square on the hypotenuse, thus
A² = 10² + 24²
Answer:
[tex] {10}^{2} + {24}^{2} [/tex]Step-by-step explanation:
Let side of the square be a
Now, let's find:
Hypotenuse ( h ) = a
Perpendicular ( p ) = 10
Base ( b ) = 24
Applying Pythagoras theorem in the right triangle formed by the square:
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
plug the values
[tex] {a}^{2} = {10}^{2} + {24}^{2} [/tex]
Hope this helps..

Distinct four-letter sequences are formed by picking 4 letter tiles from a bag containing 11 different alphabet tiles. Note that the order in which the letters are picked matters.
The probability of getting a particular four-letter sequence is .
The probability of getting a particular four letter sequence is [tex]\frac{1}{7920}[/tex].
What is permutation?
A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Formula for permutation[tex]P(n, k) =\frac{n!}{(n-k)!}[/tex]
Where:
n – the total number of elements in a set
k – the number of selected elements arranged in a specific order
! – factorial
What is probability?Probability is the measure of the likelihood of an event to occur.
Formula for probabilityP(E) = number of favorable outcomes/ total number of outcomes
According to given question
We have
Total number of tiles = 11
And we have to form distinct four letter sequences by picking 4 letter tiles a bag containing 11 different alphabet.
⇒ n = 11 and k = 4
So, the total number of distinct four letter sequences formed by picking 4 tiles from a bag = [tex]11P_{4}[/tex]
⇒ total number of distinct four letters = [tex]\frac{11!}{(11-4)!} = 7920[/tex]
Since, we have to get only one particular sequence.
⇒ Total number of favorable outcomes = 1
And there are total number of four teller sequence = 7920
⇒ Total number of outcomes = 7920
Therefore, the probability of getting a particular four letter sequence = [tex]\frac{1}{7920}[/tex]

Resulting in 1152 :)
ASAP!! can someone help answer these and include work, whoever answers most gets brainliest!! i underlined the questions
your work for the first one is perfect!!
the second one gives you the side lengths of x+2 and x-5. the formula for the area of a rectangle is l×w so you have to multiply (x+2)(x-5) and im sure you can figure that out but the answer to that is x^2-3x-10
you set up number 3 right, you just need to continue with the distribute property which would give you 4x^2-20x+25
number 4 is the same as the other ones and the answer is 36x^2-1
number 5 is just distributing the -z^3 into everything in the parenthesis giving you -5z^3-z^4+4z^5
I cant see all your work for number 6, but I can see that your term for c is 5, when it is actually -5. it looks like you didnt subtract it to make the quadratic equal to zero and to do that you would have to subtract 5.

Lincy is standing 20 feet from the circular wall of an above ground swimming pool and 49 feet from a point of tangency. Find the radius of the pool.
Answer:
the radius of the pool is 50.025 feet
Step-by-step explanation:
From the information given:
We can have a schematic view of a diagrammatic illustration in our mind where the distance of the pool to Lincy is (20 + r ) and the distance to the tangent is 49.
So; by using pythagoras theorem, since the radius meets the tangent at a right angle; we have:
[tex]r^2 + 49^2 = ( r + 20 )^2[/tex]
[tex]r^2 +2401 = r^2 + 40r + 400[/tex]
[tex]2401 = 40r + 400[/tex]
[tex]2401- 400 = 40r[/tex]
2001 = 40 r
r = 2001/40
r = 50.025 feet
1. f(x) = x² - 4 ; if x is even = 3x – 2; if x is odd solve for f(4) and f(5)
=======================================================
Explanation:
This is a piecewise function as it is composed of two pieces.
The equation for f(x) depends on what x is. Specifically whether it is even or odd.
If x is even, then f(x) = x^2-4. If x is odd, then f(x) = 3x-2
------------
f(4) means f(x) when x = 4. We have an even number input for x, so we'll go with f(x) = x^2-4
f(x) = x^2 - 4
f(4) = 4^2 - 4
f(4) = 16 - 4
f(4) = 12
------------
When x = 5, x is now odd, so use f(x) = 3x-2
f(x) = 3x-2
f(5) = 3(5) - 2
f(5) = 15 - 2
f(5) = 13
Calculate the coefficient of x14,4 in the expansion of (x + y)18,

Step-by-step explanation:
Formula : (r+1)th term of [tex](a+b)^n[/tex] : [tex]T_{r+1}=\ ^nC_r(a)^{n-r}(b)^r[/tex]
To find: Coefficient of [tex]x^{14}y^4[/tex] in the expansion of [tex](x + y)^{18}[/tex].
Let the term in the expansion of [tex](x + y)^{18}[/tex] be [tex]^{18}C_r x^{18-r}y^r=x^{14}y^4[/tex]
[tex]\Rightarrow\ r=4[/tex]
Now, Coefficient = [tex]^{18}C_r=^{18}C_4=\dfrac{18!}{4!14!}[/tex] [[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]]
[tex]=\dfrac{18\times17\times16\times15\times14!}{14!(24)}\\\\=3060[/tex]
Hence, the coefficient of [tex]x^{14}y^4[/tex] in the expansion of [tex](x + y)^{18}[/tex] is 3060 .

Answer:
C. 8/9
Step-by-step explanation:
Well .8 repeating is not 8/10.
Though many would choose that.
If you do 8 ÷ 10 you get .8 not .8 repeating meaning 8/10 is not correct.
To get .8 repeating we would divide 8 by 9.
Because all natural numbers below 9 can be divided by 9 to create a .repeating itself.
For example 8 ÷ 9 = .8 repeating,
4÷9 = .4 repeating.
Thus,
C. is the correct answer.

Find the exact value of x and hence find the exact area with full working out
Answer:
x = 6 + 16 sqrt(3) / 3 or equivalently 6 + 16/sqrt(3)
Step-by-step explanation:
Have enough data to solve only for x in the diagram.
The lengths that make up the base are respectively from left to right
x1 = 4 cot(60) = 4 (3/sqrt(3)) = 4sqrt(3) m
x2 = 6 m
x3 = 4 cot(30) = 4 ( sqrt(3) / 3 ) = 4/ sqrt(3) = (4/3)sqrt(3) m
Altogether
Base, x = 4sqrt(3)/3 + 6 + 2 sqrt(3)
= 6 + 16 sqrt(3) / 3 or equivalently 6 + 16/sqrt(3)
Answer:
Step-by-step explanation:
First triangle: angles are in the ratio = 30 : 60 : 90
So, the ratio of sides = a : a√3 : 2a
a√3 = 4 m
a * 1.732 = 4
a = 4/1.732
a = 2.31
Now, in the second triangle, angles are in the ratio = 30 : 60 : 90
So, the ratio of sides = b : b√3 : 2b
b = 4 m
b√3 = 4 * 1.732 = 6.928 m
x = a + 6 + b
x = 2.31 + 6 + 6.928
x = 15.23 m
The graph for the equation y = x minus 4 is shown below. On a coordinate plane, a line goes through (0, negative 4) and (4, 0). Which equation, when graphed with the given equation, will form a system that has an infinite number of solutions? y minus x = negative 4 y minus x = negative 2
Answer:
The correct option is:
y - x = -4
Step-by-step explanation:
The graphed equation is:
y = x - 4
The equation which will have infinite number of solution should overlap the graphed equation at infinity points.
It is only possible when both the equations are exactly same.
Consider the line given:
y - x = -4
Rearrange the equation:
y = x - 4
Thus, it is the same as the first equation.
Verify for point (0,-4)
y - x = -4
-4 - 0 = -4
-4 = -4
Proved.
Verify for point (4,0)
y - x = -4
0 - 4 = -4
0 = -4+4
0 = 0
Proved
The correct option is (1). [tex]y-x= -4[/tex]
Given equation,
[tex]y = x - 4[/tex]
the line, [tex]y = x - 4[/tex] passes through the points (0, -4) and (4, 0).
Comparing with the general equation of a straight line,
[tex]y = mx + c[/tex] , where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.
The slope of the equation [tex]y = x - 4[/tex] is 1 and its The y-intercept is -4.
We know that,
Two equations will have an infinite number of solutions when they are on the same line, that is having the same slope and intercept.
Now we check for the slope and the intercept of the given options.
Option (1) [tex]y - x = -4[/tex]
[tex]y = x - 4[/tex]
Here the slope is 1 and y intercept is -4, which is the same as the given equation and both equations will have an infinite number of solutions.
Now option (2).
[tex]y - x = -2[/tex]
[tex]y=x-2[/tex]
The slope is 1 and y intercept is -2
The slope is the same as the given equation but the intercept is different giving no solution.
Hence the correct option is (1). [tex]y-x= -4[/tex]

Two ants, Andy and Ashley, went to visit their friend. Andy crawled the whole way, but Ashley spent half of the way riding on a caterpillar, which was two times slower than crawling. Ashley spent the second half of the journey riding on a grasshopper, which was 5 times faster than crawling. Which ant got to their friend's house first, if they left at the same time?
Answer:
Andy
Step-by-step explanation:
Let's say that x is Andy's speed, and d is the distance he traveled.
The time it takes Andy to reach his friend is d/x.
The time it takes Ashley to travel the first half is (d/2)/(x/2) = d/x.
The time it takes Ashley to travel the second half is (d/2)/(5x) = d/(10x).
The total time is d/x + d/(10x) = 1.1 d/x.
It takes Ashley 1.1 times longer to reach the friend. Andy gets there first.
