Answer:
x < -4
Step-by-step explanation:
To solve the inequality, use inverse operations.
-3x + 5 > 17
-3x > 17 - 5 Subtract 5 from both sides.
-3x > 12 Divide both sides by -3.
x < -4 Flip the inequality sign since you divided by a negative.
Please answer this question ASAP.
Let c = angle TPS
This angle adds to angle 'a' to get a+c = 90. We know these angles are complementary because triangle PQR is a right triangle. The acute angles of a right triangle add to 90.
We also know that b+c = 90 for similar reasons. Triangle PST is a right triangle.
So we have these two equations
a+c = 90
b+c = 90
If we were to subtract straight down then we would end up with
a-b = 0
which solves to
a = b
after adding b to both sides
If the sum of a number and its square is 182, what is the number ?
Answer:
-14 or 13
Step-by-step explanation:
x + x^2 = 182
x^2 + x - 182 = 0
rearrange and solve by completing the square
x^2 + x = 182
x^2 + x + 1/4 = 182.25
(x + 1/2)(x + 1/2) = 182.25
(x + 1/2)^2 = 182.25
x + 1/2 = root 182.25
x = + or - root 182.25 - 0.5
x = + or - 13.5 - 0.5
x = 13 or x = - 14
Answer:
- 14 or 13
Step-by-step explanation:
let the number be n then it's square is n² and
n² + n = 182 ( subtract 182 from both sides )
n² + n - 182 = 0 ← in standard form
(n + 14)(n - 13) = 0 ← in factored form
Equate each factor to zero and solve for n
n + 14 = 0 ⇒ n = - 14
n - 13 = 0 ⇒ n = 13
As a check
(-14)² - 14 = 196 - 14 = 182
13² + 13 = 169 + 13 = 182

Tori examined the pattern of exponents in the table.
Answer:
The value of b = 1/36
As exponent decreases, each previous value is divided by 6
If the table was extended, the value of 6^-3 would be 1/216
Step-by-step explanation:
Given in the question a table containing power of 6
We will use negative rule of exponent to write the equivalent of negative power of 6
b^{-n}= 1 / b^{n}
we know that
[tex]6^{1} = 6[/tex]
so
[tex]6^{-1} = \frac{1}{6^{1} }[/tex]
= 1/6
and
[tex]6^{2} = 36\\[/tex]
So,
[tex]6^{-2} = \frac{1}{6^{2} }[/tex]
= [tex]\frac{1}{36}[/tex]
What is the explicit formula for this geometric sequence? 8, 4, 2, 1
Answer:
a[n] = 2^(4-n)
Step-by-step explanation:
There are many ways the formula for the given sequence can be written. The first term (a[1]) is 8 and the common ratio (r) is 1/2, so the generic form is ...
a[n] = a[1]·r^(n-1)
a[n] = 8·(1/2)^(n-1)
___
If we recognize that 8 = 2^3 and 1/2 = 2^-1, then we can write this as ...
a[n] = 2^3·(2^-1)^(n-1) = 2^(3 -n +1)
a[n] = 2^(4 -n)

Given that cos(30°) = cos(45°)cos(15°) + sin(45°)sin(15°), it follows that cos(30°) =
Answer:
[tex]cos(30\°) = cos(45\°-15\°)[/tex]
Step-by-step explanation:
To solve this problem you must know the formula of subtraction of angles for the function cosx.
The formula is:
[tex]cos(h-d) = cos(h)cos(d) + sin(h)sin(d)[/tex]
We can write 30° as: 45° - 15°
Then:
[tex]cos(30\°) = cos(45\°-15\°)[/tex]
Using the formula for subtraction of angles we have:
[tex]cos(45\°-15\°) = cos(45\°)cos(15\°) + sin(45\°)sin(15\°)[/tex]
Notice that we have achieved the expression shown in the statement
Finally:
[tex]cos(30\°) = cos(45\°-15\°)[/tex]

The circumference of a circle is greater than the length of any of its arcs. Without knowing what fraction of the circle's circumference the arc makes up, it's impossible to calculate the exact circumference from the arc length.
Explanation:The arc length 's' is the distance traveled along a circular path, and the radius of curvature 'r', is the radius of the circular path. The circumference of a circle can be found using the formula 2πr, and the length AB, if it corresponds to the minor arc, can be the fraction of the entire circle. This fraction is determined by the relation between the length of the arc and the full circumference. Thus, if the length of AB is 20cm, then we can infer that 2πr (the full circumference) is greater than 20cm.
To find the exact value you'd need to know what fraction of the circle the minor arc AB represents. Without this information, we can only conclude that the length of the minor arc is smaller than the circumference (2πr) of the whole circle.

which ordered pair is not included in the graph of p=3m+6
A.) (1,9)
B.) (3,12)
C.) (10,36)
D.) (6,18)
Answer:
(3,12) and (6,18)
Step-by-step explanation:
An order pair is not included if it make the equation false. Substitute each pair to determine this.
(1,9) ----> 9 = 3(1) + 6 -----> 9 = 9 TRUE
(3,12) ---> 12 = 3(3) + 6 ----> 12 = 15 FALSE
(10,36) ---> 36 = 3(10) + 6 -----> 36 = 36 TRUE
(6,18) ----> 18 = 3(6) + 6 ----> 18 = 24 FALSE
The correct answer is option (B)(D) because the ordered pair (3,12) and (6,18) is not included in graph of [tex]\( p = 3m + 6 \)[/tex].
To determine which ordered pair is not included in the graph of [tex]\( p = 3m + 6 \)[/tex], we need to verify each pair against the equation [tex]\( p = 3m + 6 \)[/tex].
The equation [tex]\( p = 3m + 6 \)[/tex] represents a linear relationship where [tex]\( m \)[/tex] is the independent variable (input) and [tex]\( p \)[/tex] is the dependent variable (output).
Let's check each ordered pair:
A) [tex]\( (1, 9) \)[/tex]:
[tex]\[ p = 3 \times 1 + 6 = 3 + 6 = 9 \][/tex]
This pair satisfies the equation [tex]\( p = 3m + 6 \)[/tex].
B) [tex]\( (3, 12) \)[/tex]:
[tex]\[ p = 3 \times 3 + 6 = 9 + 6 = 15\neq 12 \][/tex]
This pair does not satisfy the equation [tex]\( p = 3m + 6 \)[/tex].
C) [tex]\( (10, 36) \)[/tex]:
[tex]\[ p = 3 \times 10 + 6 = 30 + 6 = 36 \][/tex]
This pair satisfies the equation [tex]\( p = 3m + 6 \)[/tex].
D) [tex]\( (6, 18) \)[/tex]:
[tex]\[ p = 3 \times 6 + 6 = 18 + 6 = 24 \][/tex]
This pair does not satisfy the equation [tex]\( p = 3m + 6 \)[/tex].

Graph the equation below by plotting the y-intercept and a second point on the line.
The y-intercept is the Y coordinate when X = 0
replace x with 0 and solve for Y:
y = 3/2(0)-5 = -5
The first point using the Y-intercept would be (0,-5)
Now to find another point replace X with another number other than 0 and solve for Y.
Lets use 2:
y = 3/2(2) - 5
y = 3-5 = -2
The second point would be (2,-2)
Now plot those two points and connect with a line.

Answer:
[tex]28in^{2}[/tex]
Step-by-step explanation:
We can divide the yellow area in one rectangle and two squares. The dimensions of the rectangle is 10in by 2in, because the base of such rectangle is found by subtracting 4 inches and 2 inches, that would give us the measure of the base of the rectangle.
So, the area of the rectangle is
[tex]A_{r}= 10in \times 2in = 20in^{2}[/tex]
Now, the dimensions of the square is 2 inches by 2 inches, according to the graph. So, the area of each square is
[tex]A_{s}=2in \times 2in = 4in^{2}[/tex]
The total area would be
[tex]A_{total}= A_{r}+ 2A_{s}= 20in^{2}+2 (4in^{2} )=20in^{2} +8in^{2} = 28 in^{2}[/tex]
Therefore, the right answer is [tex]28in^{2}[/tex]

The side length, s, of a cube is x – 2y. If V = s3, what is the volume of the cube?
Answer:
The volume of cube = x³ -6x²y + 12xy² - 8y³
Step-by-step explanation:
It is given that,
Side length of cube s = (x - 2y)
Volume of cube = s³
Points to remember
(a - b)³ = a³ - 3a²b + 3ab² - b³
To find the volume of cube
s = (x - 2y)
Volume V = s³ = (x - 2y)³
(x - 2y)³ = x³ - (3 * x² * 2y) + (3 * x * (2y)²) - (2y)³
= x³ -6x²y + 12xy² - 8y³
Therefore the volume of cube = x³ -6x²y + 12xy² - 8y³
Answer:
[tex]x^3 -6x^2y + 12xy^2 - 8y^3[/tex]
Step-by-step explanation:
We are given that the side length (s) of a cube is [tex]x-2y[/tex]. Given that [tex]V=s^3[/tex], we are to find the volume of the cube.
[tex]Volume = (x-2y)^3[/tex]
We know that, [tex](a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3[/tex]
So expanding the given expression accordingly:
[tex](x-2y)^3 = x^3 - (3 \times x^2 \times 2y) + (3 \times x \times (2y)^2) - (2y)^3[/tex]
Volume of cube = [tex]x^3 -6x^2y + 12xy^2 - 8y^3[/tex]

Find the area of a parallelogram who vertices ate (2,1), (7,1), (9,5) and (4,5)
Answer:
20 units
Step-by-step explanation:
The area of a parallelogram is A =b*h. Find the base and height by looking at the points. The distance between (2,1) and (7,1) is 5. The height between (9,5) and (7,1) must be found as a perpendicular height. It is 4 and is the distance between y coordinates or 5 - 1 = 4. See attached picture.
So the area is A = b*h = 5*4 = 20
