Answer:
4x-3
Step-by-step explanation:
From the length of two tangents 2x + 16 and 4x - 2. The value of x is 9.
The length of one tangent is 2x + 16.
The length of the other tangent is 4x - 2.
Theorem on the length of a tangentThe length of two tangents drawn from an external point to a circle is equal. Let's suppose AP and AQ are two tangents from point A to a circle then AP = AQ.
Consider the length of one tangent to be AP and the other tangent to be AQ from a points A to a circle.
So, from the above theorem, we get
AP = AQ
[tex]\rm 4x-2=2x+16\\\rm 4x-2x=16+2\\\rm 2x=18\\\rm x=9[/tex]
Therefore, from the length of two tangents 2x + 16 and 4x - 2. The value of x is 9.

Which expression represents the total surface area, in square centimeters, of the square pyramid? A square pyramid. The square base has side lengths of 8.2 centimeters. The triangular sides have a height of 10.3 centimeters.
Answer:
Total surface area of the pyramid is 236.16cm² and the expression is
2bs + s²
Step-by-step explanation:
Total surface area of a square pyramid is expressed as;
TSA = 2bs + Base Area
b is the side length of the base = 8.2cm
s is the slant height of the triangular side = 10.3cm
Base area = s²
Base area = 8.2²
Base area = 67.24cm²
TSA = 2(8.2)(10.3)+67.24
TSA = 168.92+67.24
TSA = 236.16cm²
Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²

What is 1 1/6 + 2 3/8 equal to?
Answer: 3 13/24
Step-by-step explanation:
First off we have an issue with the problem due to denominators not being the same
So we need to find a common denominator
The common denominator would be 24 for 6 and 8
Then we must multiply the numerator 1 by 4 and the numerator 3 by 3
Our new problem would look like

80 points!!! Which equation represents f(x)?
Of(x) = -
O f(x) = -3/x-1
O f(x) = -x-1
O f(x) = -x
Some times it's really very easy to answer the problem just by looking over the given problem.
For the given graph, we need to observe some(or any) point on the graph that can conclude anything to answer the given problem.
Generally we observe x or y-intercepts of the graph first.
Let us observe the y-intercept of the given graph, because we can see a clear picture of y-intercept there.
By looking on the graph, we can see y-intercept is at -1.
Note: y-intercept is a point on y-axis where value of x is 0.
Now let us observe the given functions in the given options.
First option: If we plug x=0 in the given function, we get f(0)=0.
So, y-intercept for first option is 0.
Second option: If we plug x=0, we get a negative -1 inside radical. Cube root of -1 is -1. On multiplying by -1 we get +1.
So, y-intercept for second option is 1.
Third option : If we plug x=0 in that function, we get 0-1 = -1.
So, the y-intercept for third function is -1.
Therefore, function in third option is the correct function for given graph.
Therefore, third option [tex]f (x) = \sqrt[3]{-x} -1[/tex] is correct option.

What is the cubic Function?A polynomial equation with a 3-exponent greatest exponent is called a cubic equation. Despite having many more uses for understanding more complex mathematics, such as calculus, cubic equations are frequently employed to calculate volumes.
Given a graph of a cubic function for calculating the cubic function we need to standardize it. since it's a single aggregate graph that standard function would be.
x = a(y + 1 )³
for the value y tends to -1. "a" will be -1.
Hence,
x = -1 (y+1)³
(y + 1 )³ = -x
y+1 = ∛-x
y = ∛-x -1
Therefore, for the given graph F(x) = y = ∛-x -1.

Step-by-step explanation:
Number 1
For parallelism.....
gradient of the two lines is the same
y = 3/2x -4
y = mx + C
m = 3/2
(-1, 0) = (x1, y1)
y - y1 = m(x - x1)
y - 0 = 3/2[x - (-1)]
y = 3/2(x + 1)
2y = 3x + 3
y = 3/2x + 3/2
Option A
Number 2
For parallelism.....
gradient of the two lines is the same
y = -½x + 2
y = mx + c
m = -½
(-2, -1) = (x1, y1)
y - y1 = m(x - x1)
y - (-1) = -½[x - (-2)]
y + 1 = -½(x + 2)
2(y + 1) = -(x + 2)
2y + 2 = -x - 2
2y = -x - 2 - 2
2y = -x - 4
y = -½x - 2
Option A
Number 3
For perpendicularity... m1 × m2 = -1
y = 4/3x - 5
y = mx + c
m1 = 4/3
m2 = -1/m1
m2 = -1/(4/3)
m2 = -3/4
(3, -1) = (x1, y1)
y - y1 = m2(x - x1)
y - (-1) = -¾(x - 3)
y + 1 = -¾(x - 3)
4(y + 1) = -3(x - 3)
4y + 4 = -3x + 9
4y = -3x + 9 - 4
4y = -3x + 5
y = -¾x + 5/4
Option A
Number 4
For perpendicularity... m1 × m2 = -1
y = -5x + 5
y = mx + c
m1 = -5
m2 = -1/m1
m2 = -1/-5
m2 = ⅕
(5, 4) = (x1, y1)
y - y1 = m(x - x1)
y - 4 = ⅕(x - 5)
5(y - 4) = x - 5
5y - 20 = x - 5
5y = x - 5 + 20
5y = x + 15
y = ⅕x + 15/5
y = ⅕x + 3
