I need help please with this 1 problem
Answer:
See below, please
Step-by-step explanation:
We know
[tex]f(x) = {x}^{2} + 3x - 7[/tex]
[tex]g(x) = 3x + 5[/tex]
[tex]h(x) = 2 {x}^{2} - 4[/tex]
Hence
[tex]f(g(x))[/tex]
[tex] = {(3x + 5)}^{2} + 3 \times (3x + 5) - 7[/tex]
[tex] = (9 {x}^{2} + 30x + 25) + (9x + 15) - 7[/tex]
[tex] = 9 {x}^{2} + 39x + 33[/tex]
[tex]h(g(x))[/tex]
[tex] = 2 \times {(3x + 5)}^{2} - 4[/tex]
[tex]2 \times (9 {x}^{2} + 30x + 25) - 4[/tex]
[tex] = 18 {x}^{2} + 60x + 50 - 4[/tex]
[tex] = 18 {x}^{2} + 60x + 46[/tex]
[tex](h - f)(x)[/tex]
[tex] = h(x) - f(x)[/tex]
[tex] = (2 {x}^{2} - 4) - ( {x}^{2} + 3x - 7)[/tex]
[tex] = {x}^{2} - 3x + 3[/tex]
[tex](f + g)(x)[/tex]
[tex] = f(x) + g(x)[/tex]
[tex] = ( {x}^{2} + 3x - 7) + (3x + 5)[/tex]
[tex] = {x}^{2} + 6x - 2[/tex]

What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The angle formed by two secants (lines cutting a circle at two places) intersecting outside the ring is half the distance between their arc minus the closest arc.
From the diagram, the equation is given as,
∠A = (arc DE - arc BC) / 2
∠A = (94° - 70°) / 2
∠A = 24° / 2
∠A = 12°
The measure of the angle ∠A will be 12°. Then the correct option is B.

The median (Q2) is the middle value = 39
Q1 is the middle value of the numbers smaller than the median = 34
Q3 is the middle value of the numbers larger than the median = 55
IQR = Q3 - Q1

What is the answer to this question?
Answer:
A = 16.5 cm²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 3, b₁ = 7 , b₂ = 4 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (7 + 4) = 1.5 × 11 = 16.5 cm²

Sophia has unsharpened pencils that are 20 centimeters long. What is the approximate surface area of a pencil?
The surface area of the pencil is the amount of space it covers
The surface area of the pencil is 61 square centimeters
How to determine the surface area?The given parameters are:
H = 20 cm
L = 0.5 cm
The surface area (SA) is then calculated as:
SA = 6LH + 3[tex]\sqrt 3[/tex]L^2
This gives
SA = 6 * 0.5 * 20 + 3[tex]\sqrt 3[/tex] * 0.5^2
Evaluate the sum
SA = 61
Hence, the surface area of the pencil is 61 square centimeters

Given f(x)= 2x^3+kx-1, and x+1 is a factor of f(x), then what is the value of k?
Answer:
put x=-1, and the rest will be easy
If x + 1 divides f(x), this means x = -1 is a root of f(x), i.e. f(-1) = 0. Plugging in x = -1 gives
f(-1) = 2 (-1)³ + k (-1) - 1 = -3 - k = 0
Solve for k; you end up with k = -3.

To solve the equation x ^2 - 2x = 3 by the technique of completing the square, you would add 4 to each side of the equation as one of the steps to reaching the solution.
Answer:
x = -1
x = 3
Step-by-step explanation:
[tex]\sf x^2 - 2x = 3[/tex]
Add 1 to both sides:
[tex]\sf \implies x^2 - 2x+1 = 3+1[/tex]
Factor the left side:
[tex]\sf \implies (x-1)^2 = 4[/tex]
Square root both sides:
[tex]\sf \implies x-1 = \pm2[/tex]
Therefore:
[tex]\sf \implies x-1=-2 \implies x=-1[/tex]
[tex]\sf \implies x-1=2 \implies x=3[/tex]

A sollid piece of iron in the form of a cuboid of dimensions 49cm × 33 cm× 24 cm , is moulded to form a solid sphere. find the radius of the sphere
Answer:
Radius of sphere is 21 cmStep-by-step explanation:
Given:
A sollid piece of iron in the form of a cuboid of dimensions 49cm × 33 cm× 24 cm , is moulded to form a solid sphere.To Find:
Radius of the sphereSolution:
Volume of sphere = Volume of cubiod
↠ 4/3 πr³ = LBH
↠ 4/3 × 22/7 × r³ = 49 × 33 × 24
↠ 4/3 × 22/7 × r³ = 38808
↠ 4 × 22/7 × r³ = 38808/3
↠ r³ = 38808 × 3 × 7/4 × 22
↠ r³ = 441 × 21
↠ r³ = 9261
↠ r = 21 cm
Hence,
Radius of sphere is 21 cmAnswer:
21.00 cm to the nearest hundredth.
Step-by-step explanation:
The volume of the sphere will be equal to the volume of the cuboid.
So 4/3 π r^3 = 49*33*24 where r = radius of the sphere.
r^3 = (49*33*24 ) / 4/3 π
r^3 = 38808 / 4.18879
= 9264.728
r = ∛9264.728
= 21.0028 cm.
