Answer:
Step-by-step explanation:
f(x) =-3x - 7
f(g(x)) = -3*g(x) - 7
f(g(x)) = -3*x^4 - 7
bottom left.
ANSWER
[tex](f\circ g)(x) = - 3 {x}^{4} - 7[/tex]
EXPLANATION
It was given that;
[tex]f(x) = - 3x - 7[/tex]
and
[tex]g(x) = {x}^{4} [/tex]
We want to find the composite function,
[tex](f\circ g)(x) = f(g(x))[/tex]
[tex](f\circ g)(x) = f( {x}^{4} )[/tex]
We plug in x⁴ into f(x)=-3x-7 to obtain:
[tex](f\circ g)(x) = - 3 {x}^{4} - 7[/tex]
What is the value of X?
Answer:
x = 11
Step-by-step explanation:
Since they are vertical angles, the angles are equal. Set them equal and solve for x.
5x + 10 = 7x - 12 Subtract 5x from both sides
10 = 2x - 12 Add 12 to both sides
22 = 2x Divide by 2
11 = x

The function f(x)=3g(x). Which of the following shows possible graphs of f(x) and g(x)?
Answer:
The answer is the first graph in the second raw
Step-by-step explanation:
* Lets study the dilation:
- A vertical stretching is the stretching of the graph away
from the x-axis
- A vertical compression is the squeezing of the graph
toward the x-axis.
- if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically
stretched by multiplying each y-coordinates by k.
- if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each y-coordinates by k.
* Notice that the "roots" on the graph stay in their same
positions on the x-axis.
* Lets check our question:
∵ f(x) = 3g(x)
∵ f(x) = k.g(x)
∴ It is a vertical stretching or vertical compression
∵ k = 3 > 1
∴ It is vertical stretching with scale factor = 3
* That means we will multiply each y-coordinates in g(x) by 3
∴ The graph of f(x) will be away from x- axis and narrow to y- axis
∴ The answer is the first graph the second raw
Example: If g(x) = x²
∴ f(x) = 3x²
* Look to the graph:
- The red is the graph of g(x)
- The blue is the graph of f(x)
- f(x) = 3g(x)

The blue shaded region is a sector of a circle. The formula for area of sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]
Where [tex]\theta[/tex] is the central angle and r is the radius
For the diagram, we have 80° arc and 180° arc as the "white" area. Since the whole circle is 360°, the shaded region arc is 360 - (80+180) = 100°. this is [tex]\theta[/tex] and the radius is 6.
Plugging in it in the formula we get:
Area of shaded region = [tex]\frac{\theta}{360}*\pi r^2\\=\frac{100}{360}*\pi(6)^2\\=31.42[/tex] cm^2
16.
We can say that area of shaded region = area of parallelogram - area of circle
Now,
Area of Parallelogram = b * h
where
b is the base (it is 6+3=9) and h is the height (diameter of the circle is the height = 6)
Area of Parallelogram = 9 * 6 = 54
Area of Circle = πr^2 where r is the radius, which is 6/2=3
Area of Circle = π(3)^2 = 9π
Now,
Area of Shaded Region = 54 - 9π = 25.73 m^2
17.
For the first figure (rectangle) we could let the height be h (since not given). So area of yellow region would be 4h (area of rectangle is base * height)
And area of whole ruler would be 8*h = 8h
So probability of landing in yellow region would be [tex]\frac{4h}{8h}=\frac{1}{2}=0.5[/tex]
For 2nd figure, the yellow region has area of π(2)^2 = 4π ( radius of yellow circle is 2 and area of circle is πr^2)
Area of whole circle is π(4)^2 = 16π
So probability of landing in yellow region would be [tex]\frac{4\pi}{16\pi}=\frac{1}{4}=0.25[/tex]
Hence, Fly A is more likely to land in a yellow region.

solve the quadtdd atic function (x + 1)2 = 16
Answer:
x = 15 or x = -17
Step-by-step explanation:
It is given that,
(x + 1)² = 16
To solve the quadratic equation
The give equation is
(x + 1)² = 16 ----(1)
From equation (1) we can see that it is a quadratic equation
So we can take square root fro both sides we get
√[(x + 1)²] =√16
x + 1 = ±16
x + 1 = 16 or x + 1 = -16
x = 16 - 1 = 15 or x = -16 - 1 = -17
Therefore x = 15 or x = -17

3/8 c−2= 3/2 c−12 solve for c
To solve the equation 3/8c -2 = 3/2c -12 for c, first clear the fractions by multiplying the entire equation by 8. Then, use algebraic operations to isolate and solve for c, yielding the solution c = 80/9 or about 8.89.
Explanation:The given algebraic equation is 3/8 c−2= 3/2 c−12. Our goal is to solve for c. Here's how:
First, let's multiply the whole equation by 8 to clear out the fractions: 8*(3/8c-2) = 8*(3/2c -12) which simplifies to 3c - 16 = 12c - 96. Next, subtract 3c from both sides of the equation to collect all the terms with c on one side: -16 = 9c - 96. Now, add 96 to both sides to isolate the c term: 80 = 9c. Finally, divide both sides by 9 to solve for c: c = 80/9 or approximately 8.89.
So, the solution to the equation 3/8c - 2 = 3/2c -12 is c = 80/9 or about 8.89.

Step-by-step explanation:
A line joins the point
is the point of intersection of 5x - 2y + 3 = 0 and 4x - 3y + 1 = 0 to
of intersection of x = y and x = 3y + 4.find the equation of the line.
Intersection of the first two lines:
[tex]\begin{cases}5x - 2y + 3 = 0\\4x - 3y + 1 = 0\end{cases}[/tex]
Multiply the first equation by 4 and the second by 5:
[tex]\begin{cases}20x - 8y + 12 = 0\\20x - 15y + 5 = 0\end{cases}[/tex]
Subtract the two equations:
[tex](20x - 8y + 12)-(20x - 15y + 5)=0 \iff 7y+7=0 \iff y=-1[/tex]
Plug this value for y in one of the equation, for example the first:
[tex]5x - 2\cdot (-1) + 3 = 0\iff 5x+5=0 \iff x=-1[/tex]
So, the first point of intersection is [tex](-1,-1)[/tex]
We can find the intersection of the other two lines in the same way: we start with
[tex]\begin{cases}x=y\\x=3y+4\end{cases}[/tex]
Use the fact that x and y are the same to rewrite the second equation as
[tex]x=3x+4 \iff 2x=-4 \iff x=-2[/tex]
And since x and y are the same, the second point is [tex](-2, -2)[/tex]
So, we're looking for a line passing through [tex](-1,-1)[/tex] and [tex](-2, -2)[/tex]. We may use the formula to find the equation of a line knowing two of its points, but in this case it is very clear that both points have the same coordinates, so the line must be [tex]y=x[/tex]
In the attached figure, line [tex]5x - 2y + 3 = 0[/tex] is light green, line [tex]4x - 3y + 1 = 0[/tex] is dark green, and their intersection is point A.
Simiarly, line [tex]x=y[/tex] is red, line [tex]x = 3y + 4[/tex] is orange, and their intersection is B.
As you can see, the line connecting A and B is the red line itself.
To answer the student’s question, solve for points of intersection of given pairs of equations, use these points to calculate the slope, and then apply the point-slope or two-point form to determine the equation of the line.
Explanation:To find the equation of a line that passes through the points of intersection of two sets of equations, we first need to determine the coordinates of these intersection points. We have two given sets of equations: 5x - 2y + 3 = 0 and 4x - 3y + 1 = 0, as well as x = y and x = 3y + 4. To solve for the intersection points, we can use substitution or elimination method for the pairs of equations separately.
Once we have found the two points of intersection, we use these points to determine the slope of the line (using the slope formula ∆y /∆x). After that, we apply the point-slope form or the two-point form of the equation of a line to find the equation that contains both points. The final step would be to simplify the equation to its standard form.
However, the question seems to include extraneous information, as the equation provided for a specific line, y = 9 + 3x, does not directly pertain to the given task of determining the equation of the line through the points of intersection. It does illustrate that a line's equation can be represented in the form y = mx + b, where m represents the slope, and b represents the y-intercept.

What is the slant height x of this square pyramid?
The figure shows a square pyramid. The slant height is shown as a dashed line perpendicular to the base edge and is labeled as x. The length of the lateral edge is 4 meters. The lateral edge makes a 60 degree angle with the base edge.
Answer:
= 2√3 m or 3.464
Step-by-step explanation:
Using the sine,
sin(60”) = x / 4 multiply both sides by 4
4 sin (60°) = x
4 * √3 / 2 = x
x = 2√3 m
slant height =2√3 m
Answer: The slant height is 2√3 meters.
Step-by-step explanation: The side adjacent to the 60 degree angle in the right triangle consisting of x, the lateral edge, and half of the base edge is half of the base edge, 2m. The side opposite of that angle is x. So basically you have tan(60°) = x/(2m)*tan(60°) = x = 2√3m. So thus the slant height is 2√3 meters.
