Answer:
1, 2, 5 and 6 are the answers.
Step-by-step explanation:
2 is correct because the arrow shows that the number line continues till infinity. 5 is correct because any fraction is possible as no restriction of integer value is placed. Any number less than 7 is not included. There are some confusions with 1 as it's not a solid color, So, I assume -7 is not included.
How many different "words" can be made from the given word by re-arranging the letters in MATH
Answer: 24 different words
Step-by-step explanation:
Given the word : ' MATH'
To determine the number of words that can be formed by Rearranging the alphabets in the word, we need to know the length of the given word.
We also need to note if there are Repetition of alphabets in the word.
Length of Given word 'MATH' = 4
since none of the alphabets in the word are repeated ;
Number of words that can be formed by Rearranging 'MATH' = 4!

Graph the line: through the point (−8, 1) with a slope of 3. PLEASE HELP I HAVE 20 MINUTES LEFT
Answer:
[see below]
Step-by-step explanation:
We have the point of (-8,1) and a slope of three. We can use y = mx+ b to find the equation and graph the line.
I replaced 'x' and 'y' with the appropriate values, along with 'm' for three.
1 = 3(-8) + b
We can solve for 'b' to get the y-intercept.
1 = 3(-8) + b
1 = -24 + b
1 + 24 = -24 + 24 +b
25 = b
So, we can use the points (0,25) and (-8,1) to graph the line.
A sector whose central angle measures 1200 has an area of 12 square inches. What
is the radius of the circle?
This question is not correctly written
Correct Question
A sector whose central angle measures 120° has an area of 12 square inches. What is the radius of the circle?
Answer:
Radius of the circle = 3.3851375013 inches
Approximately to one decimal place, radius of the circle = 3.4 inches
Step-by-step explanation:
The formula for the area of a sector is given as:
Area of a sector = θ × π/360 × r²
θ = Central angle in degrees = 120°
Area of a sector = 12 in²
12 = (120° × π)/360 × r²
r² = 12 ÷(120° × π)/360
r² = 12 ÷ 1.0471975512
r² = 11.459178217
r = √11.459178217
r = 3.3851375013 inches
Approximately to one decimal place, radius of the circle = 3.4 inches
Find the focus and the directrix of the parabola with the equation y = 1∕4(x – 6)2+ 5
Question 16 options:
A)
Focus = (5,–6), directrix is y = –7
B)
Focus = (6,6), directrix is y = 4
C)
Focus = (6,–6), directrix is y = –4
D)
Focus = (–5,6), directrix is y = –4
Answer:
B)
Focus = (6,6), directrix is y = 4
Step-by-step explanation:
A parabola is the locus of a point that is equidistant from a fixed line (known as directrix) and a fixed point (known as focus).
The equation of a parabola in vertex form is given as:
[tex]y=a(x-h)^2+k[/tex]
It can be further simplified to:
[tex](x-h)^2=4p(y-k)[/tex]
The directrix of this parabola is given at line y = k - p and the focus is at (h, k + p)
Given that:
[tex]y = \frac{1}{4}(x-6)^2+ 5 \\(y-5)=\frac{1}{4}(x-6)^2\\(x-6)^2=4(y-5)[/tex]
Comparing (x-6)² = 4(y-5) with (x-h)² = 4p(y-k), It can be gotten that h = 6, p =1 and k = 5
The directrix of this parabola is given at line y = k - p = 5 - 1 = 4 and the focus is at (h, k + p) = (6, 5+1) = (6, 6)
Focus = (6,6), directrix is y = 4

The set of all real numbers x that satisfies 5 5x58 is given by the following interval notation:
[5,8]
The question is a True or False question
Answer:
True
Step-by-step explanation:
Given
5 ≤ x ≤ 8
Required
Is [5,8] the interval of the given range?
The interval given shows that the range of x begins at 5 and ends 8.
Start by splitting the interval to different inequalities.
1. 5 ≤ x
This implies that 5 is less than or EQUAL TO x;
The keyword needed here is EQUAL TO;
The fact that the inequality gives room for EQUALITY (=) means that the interval begins exactly at 5
2. x ≤ 8
This implies that x is less than or EQUAL TO 8;
Similarly, the keyword needed here is EQUAL TO;
The fact that this inequality gives room for EQUALITY (=) means that the interval ends exactly at 8
So, this implies that the range of values of 5 ≤ x ≤ 8 is 5, 6, 7, 8
And can be represented with [5,8]
So, the statement is true.
WILL GIVE BRAINLIEST AND 25 POINTS! Find the value of x and y, given the following matrix equation: x= y=
Answer:
x = ±6
y = 10
Step-by-step explanation:
Solve for the top part.
x² + -4 = 32
x² = 32 + 4
x² = 36
x = √36
x = ±6
Solve for bottom part.
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 4
1y = 10
By solving the upper part and the lower part of the matrix equation, the value of x and y are:
[tex]\mathbf{x = \pm6}\\\\\mathbf{y = 10}[/tex]
The given matrix equation can be solved by taking the upperpart to create an equation to solve for x, and also taking the lower part to create an equation to solve for y.
Thus:[tex]x^2 + (-4) = 32[/tex] (upper part)
[tex]y + y - 4 = y + 6[/tex] (lower part)
Solve each of the equation in the matrix.
Solve the upper part for x:
[tex]x^2 + (-4) = 32\\\\x^2 - 4 = 32[/tex]
Add 4 to both sides[tex]x^2 - 4 + 4 = 32 + 4\\\\x^2 = 36[/tex]
Take the square of both sides[tex]x = \sqrt{36} \\\\\mathbf{x = \pm6}[/tex]
Solve the lower part for y:
[tex]y + y - 4 = y + 6\\\\[/tex]
Add like terms[tex]y + y - 4 = y + 6\\\\2y - 4 = y + 6\\\\2y - y = 4 + 6\\\\\mathbf{y = 10}[/tex]
Thus, by solving the upper part and the lower part of the matrix equation, the value of x and y are:
[tex]\mathbf{x = \pm6}\\\\\mathbf{y = 10}[/tex]

John and 4 friends are going out for pizza for lunch . They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50. Write an equation to model the situation, and find the cost of one large drink.
Answer:
The cost of one large drink is $1.50.
(13.5-10) + 4 = (7.5 ÷ 5) = $1.50
Step-by-step explanation:
The first step is to minus the $10.00 from the $13.50, which gives us $3.50.
13.5 - 10
We've done this because the pizza is irrelevant to what we're trying to figure out, so we subtract the price of the food, which as we already know is $10, to isolate the price of the 5 drinks to make it easier to find the price of just one.
Once we've done that, we're going to add on the $4.00 they got discounted to the $3.50 in order to find the original price of the drinks without using the gift certificate.
(13.5 - 10) + 4
This gives us $7.50, or the price of 5 large drinks. But we're only looking for the price of one. So we're going to divide the 7.50 by the total number of drinks ordered.
(13.5-10) + 4 = (7.5 ÷ 5)
This gives us 1.5, or $1.50.
(13.5-10) + 4 = (7.5 ÷ 5) = $1.50
Hope this was helpful!

Hi, since the situation forms a right triangle we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case CB ) and a and b are the other sides.
Replacing with the values given:
CB^2 = CA^2 + AB^2
25^2 = 7^2 + x^2
Where x is the value that we are searching for..
625= 49 + x^2
625 -49 = x^2
576 = x^2
√576 = x
24 = x
So, AB= 24 ft

Solve the equation -7 = y for x.
A. x= 4y - 28
B. x = y - 28
C. x = 4y + 28
D. x = 4y + 7
Answer:
x = 4y+28
Step-by-step explanation:
x/4 -7 = y
Solve for x
Add 7 to each side
x/4 -7+7 = y+7
x/4 = (y+7)
Multiply each side by 4
x/4*4 = 4(y+7)
x = 4y+28
Answer: X = 4y + 28
Step-by-step explanation: Our first step will be to solve for x.
To do this, we first add 7 to both sides.
This gives us x/4 = y + 7.
Now we want to multiply each side of the equation by 4.
So we get x/4(4) = 4(y + 7).
On the right, distribute the 4 through the parenthses!
Simplifying from here, we get x = 4y + 28.
So this is our final answer.

Split up the interval [0, 2] into n equally spaced subintervals:
[tex]\left[0,\dfrac2n\right],\left[\dfrac2n,\dfrac4n\right],\left[\dfrac4n,\dfrac6n\right],\ldots,\left[\dfrac{2(n-1)}n,2\right][/tex]
Let's use the right endpoints as our sampling points; they are given by the arithmetic sequence,
[tex]r_i=\dfrac{2i}n[/tex]
where [tex]1\le i\le n[/tex]. Each interval has length [tex]\Delta x_i=\frac{2-0}n=\frac2n[/tex].
At these sampling points, the function takes on values of
[tex]f(r_i)=7{r_i}^3=7\left(\dfrac{2i}n\right)^3=\dfrac{56i^3}{n^3}[/tex]
We approximate the integral with the Riemann sum:
[tex]\displaystyle\sum_{i=1}^nf(r_i)\Delta x_i=\frac{112}n\sum_{i=1}^ni^3[/tex]
Recall that
[tex]\displaystyle\sum_{i=1}^ni^3=\frac{n^2(n+1)^2}4[/tex]
so that the sum reduces to
[tex]\displaystyle\sum_{i=1}^nf(r_i)\Delta x_i=\frac{28n^2(n+1)^2}{n^4}[/tex]
Take the limit as n approaches infinity, and the Riemann sum converges to the value of the integral:
[tex]\displaystyle\int_0^27x^3\,\mathrm dx=\lim_{n\to\infty}\frac{28n^2(n+1)^2}{n^4}=\boxed{28}[/tex]
Just to check:
[tex]\displaystyle\int_0^27x^3\,\mathrm dx=\frac{7x^4}4\bigg|_0^2=\frac{7\cdot2^4}4=28[/tex]
