What’s the answer ?
Answer:
1
Step-by-step explanation:
Translation of a function h units to the right is accomplished by replacing x in the function definition with (x-h).
Here, x has been replaced by x-4, so we expect to see the graph look like the original function graph shifted 4 units to the right.
That matches Graph 1.

6. The angles of triangle ABC measure 30 degrees, 40 degrees, and 110 degrees. Will
its circumcenter fall inside the triangle, on the triangle, or outside the
triangle? Explain your reasoning.
Answer: Outside the triangle
Step-by-step explanation:
Because one of the angles has a measure greater than 90 degrees, we know that the triangle must be obtuse. Therefore, the circumcenter must fall outside the triangle because in an obtuse triangle, the circumcenter is always located outside of the triangle.

An 8-sided solid is labeled with faces 1, 2, 3, skip, 4, 5, 6, skip. What is the sample space for the number solid, and what is the probability of rolling a 1?
A.
{1,2,3,4,5,6,skip,skip}; P(1)=0.125
B.
{1,2,3,skip,4,5,6}; P(1)=0.14
C.
{1,2,3,4,5,6, skip}; P(1)=0.125
D.
{1,2,3,4,5,6}; P(1)=0.17
Using it's concepts, it is found that the sample space and the desired probability are given by:
C. {1,2,3,4,5,6,skip}; P(1)=0.125
What is the sample space of an experiment?The sample space is the set that contains all possible outcomes for an experiment.
If an outcome happens more than once, as is the case for the "skip" in this problem, it is shown only once on the sample space, hence for this problem it is given by:
{1,2,3,4,5,6, skip}
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, one out of eight outcomes result in a one, hence:
P(1) = 1/8 = 0.125.
Which means that option C is correct.

Answer:
a) maximum; the parabola opens downward
b) positive; it must lie above the x-axis
c) x = 1.5
Step-by-step explanation:
The x-intercepts of a function are the points where the graph of the function crosses the x-axis. The y-values there are zero.
The "differences" of a function are related to the average slope between adjacent points. Second differences are related to the rate of change of the slope of the function. When second differences are negative, as here, the slope of the quadratic function is decreasing, becoming more negative. We say the curvature of the function is negatve, and that it opens downward.
__
a, b.If the graph of the parabola opens downward, and it crosses the x-axis, it must have a maximum that is a positive value of y.
__
c.The graph of a parabola is symmetrical about its vertex. That means points on the same horizontal line are the same distance from the line of symmetry, which must go through the vertex. The x-coordinate of the vertex will be the x-coordinate of the midpoint between the two x-intercepts:
x = (-2 +5)/2 = 3/2
The x-coordinate of the vertex is x = 1.5.
______
Additional comment
The attachment shows a table with three evenly-spaced points on the curve. The calculations show first differences (d1) and second differences (d2). You can see that the sign of the second diffference is negative, in agreement with the given conditions.
Solve and describe the steps used to find x for the equation 4 (x+4) – 10 = 14
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Given equation:
[tex]4(x+4)-10=14[/tex]
Add 10 to both sides:
[tex]\begin{aligned}4(x+4)-10+10 & =14+10\\ 4(x+4) & =24\end{aligned}[/tex]
Divide both sides by 4:
[tex]\begin{aligned}\dfrac{4(x+4)}{4} & =\dfrac{24}{4}\\ x+4 & =6\end{aligned}[/tex]
Subtract 4 from both sides:
[tex]\begin{aligned}x+4-4 & =6-4\\x & =2\end{aligned}[/tex]
Therefore, the solution is [tex]x=2[/tex]
Answer:
x = 2
Step-by-step explanation:
To solve the expression, we need to isolate the "x" variable. Start out by simplifying the distributive property on the left hand side.
⇒ 4(x + 4) - 10 = 14⇒ 4x + 16 - 10 = 14Simplify the left hand side as needed to determine the "x" variable.
⇒ 4x + 6 = 14Subtract 6 both sides to isolate the "x" variable and it's cooeficient.
⇒ 4x + 6 - 6 = 14 - 6⇒ 4x = 8Divide both sides by 4 to isolate the "x" variable. Our solution will be a constant on the right hand side.
⇒ 4x/4 = 8/4⇒ x = 2Thus, the value of x is 2.

Step-by-step explanation:
So what you want to know is what are the odds of drawing 4 5 6 out of 13.
P(4 5 6) = 3/13
Odds are a little bit different. You are still getting some idea of how likely an event is.
The formula is Probabity / ( 1 - Probability)
So The probability = 3/13
1 - probability = 1 - 3/13 = 10/13
probability / (1 - probability ) = 3/13 // 10/13 = 3/13 * 13/10 = 3 / 10 or 3 chances in 10.
I think Probability is more intuitively correct.
Answer:

What is the ratio of the surface areas of two cones if the radius of one is 3 en and the slant height is 7 cm, and the other has a radius of 5 cm and a slan Height of 9 cm?
Given Information :-
⠀
A cone with dimensions :-
Radius = 3 cmSlant height ( l ) = 7 cm⠀
Another cone with dimensions :-
⠀
Radius = 5 cmSlant height = 9 cm⠀
To Find :-
⠀
The ratio of their total surface area⠀
Formula Used :-
⠀
[tex] \qquad \diamond \: \underline{ \boxed{ \red{ \sf T.S.A._{Cone}= \pi r(r+l) }}} \: \star[/tex]
⠀
Solution :-
⠀
For the first cone,
⠀
Since, we don't really have to find the exact values of the surface area, we will let pi remain as a sign itself, this will make the calculations easier.
⠀
[tex] \sf \longrightarrow T.S.A. = \pi \times 3(3 + 7) \\ \\ \\ \sf \longrightarrow T.S.A. = \pi \times 3 \times 10 \: \: \: \\ \\ \\ \sf \longrightarrow T.S.A. =30 \pi \: {cm}^{2} \: \: \: \: \: \: \: \: \\ \\ [/tex]
Now, for the second cone,
⠀
[tex] \sf \longrightarrow T.S.A. = \pi \times 5(5 + 9) \\ \\ \\ \sf \longrightarrow T.S.A. = \pi \times 5 \times 14 \: \: \: \: \\ \\ \\ \sf \longrightarrow T.S.A. =70 \pi \: {cm}^{2} \: \: \: \: \: \: \: \: \: \\ \\ [/tex]
Now, we just have to calculate the ratio of their surface areas, thus,
⠀
[tex] \sf \longrightarrow Ratio = \dfrac{Surface ~area~of~first~cone}{Surface ~area~of~second~cone} \\ \\ \\ \sf \longrightarrow Ratio = \frac{30 \pi \: {cm}^{2} }{70 \pi \: {cm}^{2} } \: \: \: \: \: \: \: \: \: \qquad \qquad \qquad \\ \\ \\ \sf \longrightarrow Ratio = \frac{ 3 \cancel{0 \pi \: {cm}^{2}} }{ 7 \cancel{0 \pi \: {cm}^{2} } } \qquad \qquad \qquad \qquad \\ \\ \\\sf \longrightarrow Ratio = \frac{3}{7} = 3 : 7 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ [/tex]
Thus, the ratio between the surface areas of the cones is 3 : 7.

Write an equation of the line that passes through (1,2) and is parallel to the line y=-5x+4
The equation of the line that passes through (1,2) and is parallel to the line y=-5x+4, is y=-5x+7.
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
[tex]y=mx+c[/tex]
Here, (m) is the slope of the line and (c) is the y intercept.
This line is parallel to the line which has to be find out is,
[tex]y=-5x+4[/tex]
As the parallel lines have same slope. Thus, the line which is required to find has a slope of -5.
Compare with standard equation of line, we get the slope of the line,
[tex]m=-5[/tex]
Thus, the equation of line become,
[tex]y=-5x+c[/tex]
The line passes through (1,2). Put these values in the above equation as,
[tex]2=-5(1)+c\\2=-5+c\\c=2+5\\c=7[/tex]
Thus, the equation become,
[tex]y=-5x+7[/tex]
Hence, the equation of the line that passes through (1,2) and is parallel to the line y=-5x+4, is y=-5x+7.

Jordan is making a scale model of the Hanging Gardens of Babylon, one of the seven wonders of the ancient world. The actual gardens were said to be 24.4 meters tall. Jordan uses a scale of 1 cm = 0.5 m.
To the nearest tenth of a centimeter, what should be the height of Jordan’s model?
A. 12.2 cm
B. 24.4 cm
C. 48.8 cm
D. 122.0 cm
Jordan's scale model would let him have a proportional measurement of the actual drawing
The height of Jordan's model is 48.8 cm
How to determine height of Jordan's model?The scale ratio is represented as:
Ratio = Model : Actual
So, we have:
1 cm : 0.5 m = Model : 24.4 m
Express as fractions
1 cm / 0.5 m = Model / 24.4 m
Multiply both sides by 24.4 m
Model = 24.4 m * 1 cm / 0.5 m
Evaluate the product
Model = 48.8 cm
Hence, the height of Jordan's model is 48.8 cm
