1. The diagram shown is two intersecting lines. The measure of (5 is 47°.
(a) What is the measure of {7 ? How do you know. Explain your answer in complete sentences.
(b) Suppose the measure of {6 can be represented by (2x-5) . What equation can be written to solve for the value of x?
(c) What is the value of x?
By using what we know about intersecting lines, we will see that:
a) ∡7 = 47°b) 47° + (2x - 5)° = 180°c) x = 69How to get the measures of the angles for two intersecting lines?When two lines intersect, 4 angles are formed. There are two properties that these angles have.
If the angles are adjacent, then their measures add up to 180°If the angles are not adjacent, these angles have the same measure.a) We know that ∡5 = 47°
And 7 is not adjacent to 5, then 7 has the same measure:
∡7 = 47°
b) 6 and 5 are adjacent, then we must have that:
∡5 + ∡6 = 180°
47° + (2x - 5)° = 180°
That is the equation we need to solve to get the value of x.
c) To solve the linear equation we need to isolate x, let's do that:
47° + (2x - 5)° = 180°
(2x - 5)° = 180° - 47° = 133°
2x - 5 = 133
2x = 133 + 5 = 138
x = 138/2 = 69.

Given that, 2x^3 + 5x^2+7x + 23 = A(x+1)^3+ B(x + 1)^2 +Cx+ 22 for all values of x, evaluate A, B and C. Hence, state the remainder when 2x^3 +5x^2 + 7x+23 is divided by x^2 + 2x +1.
Answer:
A = 2
B = -1
C = 3
remainder= 19
Step-by-step explanation:
A(x+1)³ + B(x+1)² + Cx + 22 =
A(x³ + 3x² + 3x + 1) + B(x² + 2x + 1) + Cx + 22 =
Ax³ + (3A + B)x² + (3A + 2B + C)x + (A + B + 22) =
2x³ + 5x² + 7x + 23
→
A = 2
3A + B = 5 → 3(2) + B = 5 → B = 5 - 6 → B = -1
3A + 2B + C = 7 → 3(2) + 2(-1) + C = 7 → C = 7 - 6 + 2 →
C = 3
remainder :
(2x³ + 5x² + 7x + 23 )/ (x² + 2x + 1) =
(2x³ + 5x² + 7x + 23 )/ (x + 1)²
→
(x + 1)² = 0 → x = -1
2(-1)³ + 5(-1)² + 7(-1) + 23 = -2 + 5 - 7 + 23 = 19
The graph of f(x) = x2 is translated to form g(x) = (x – 5)2 + 1. On a coordinate plane, a parabola, labeled f of x, opens up. It goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). Which graph represents g(x)? On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10). On a coordinate plane, a parabola opens up. It goes through (2, 8), has a vertex at (5, negative 11), and goes through (8, 8). On a coordinate plane, a parabola opens up. It goes through (negative 8, 10), has a vertex at (negative 5, 1), and goes through (negative 2, 10). On a coordinate plane, a parabola opens up. It goes through (negative 8, 8), has a vertex at (negative 5, negative 11), and goes through (negative 2, 8).
Answer:
The option which is:
On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).
Step-by-step explanation:
At first we should know the rules of translation
1) {f(x) + a} is f(x) shifted up (a) units
2) {f(x) – a} is f(x) shifted down (a) units
3) {f(x + a)} is f(x) shifted left (a) units.
4) {f(x – a)} is f(x) shifted right (a) units.
Given:
f(x) = x²
g(x) = (x-5)² + 1
By comparing [ the translation from f(x) to g(x) ] with the rules of translation
We can deduce that g(x) is the image of f(x) by translation 5 units right and 1 unit up ( rules 1 and 4)
See the attached figure which represent the graph of f(x) and g(x)
As shown g(x) goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10)

What is the value of x?
to
x = [?]°
o
Answer:
The value of x from the figure is 58 degrees
To get the value of x, we will use the formula:
The angle at the vertex = 1/2(difference of angles at the arc)
Angle at the vertex = 1/2(160 - x)
51 = 1/2(160 - x)
102 = 160 - x
x = 160 - 102
x = 58 degrees
Hence the value of x from the figure is 58 degrees
The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radius of the base?
Answer:
h = 4 cm
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where V is the volume, r is the radius, and h is the height.
We are given V = 64π, and r = 4, plug those in and solve for h
64π = π(4²)h
64π = 16πh
(64π)/(16π) = (16πh)/(16π) (divide both sides by 16π)
4 = (16π)/(16π)h
4 = h
Here, we are provided a right circular cylinder with :
Volume = 64 π cubic yards Height = 4 yards Radius = ?We know that :
[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak { Volume = \pi r^2 h }}}[/tex]
Therefore,
[tex] \implies\quad \sf{V = \pi r^2 h }[/tex]
[tex] \implies\quad \sf{64\pi = \pi r^2 \times 4 }[/tex]
[tex] \implies\quad \sf{ \pi r^2 \times 4 = 64\pi}[/tex]
[tex] \implies\quad \sf{r^2 =\dfrac{64\pi}{\pi \times 4} }[/tex]
[tex] \implies\quad \sf{ r^2 =\dfrac{\cancel{64}}{\cancel{4}}\times \cancel{\dfrac{\pi}{\pi}}}[/tex]
[tex] \implies\quad \sf{ r^2 = 16}[/tex]
[tex] \implies\quad \sf{r=\sqrt{16} }[/tex]

Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through
the point (9,-2)
A. y=-1/3x +1
B. y=-1/3x-5
C. y=1/3x-5
D. y = 3x-29
Answer:
y=3x-7
Step-by-step explanation:
To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b So now we know the y-intercept and slope. We just put them together now
y=3x-7

1.25 is the quotient when 5 is divided by 4.
What is Division?A division is a process of splitting a specific amount into equal parts.
In division, the dividend( the number being divided) is divided by the divisor (the number you are dividing by) to get the quotient (the result of the division).
In this case, the dividend is 5 and the divisor is 4.
So, 5 divided by 4 is equal to 1.25:
Five divided by four equal to one point two five.
5 ÷ 4 = 1.25
Hence, 1.25 is the quotient when 5 is divided by 4.
