Answer:
Step-by-step explanation:
From the picture attached,
Function given is a parabola, therefore, function is a quadratic function.
Domain of the function : x-values(input values) on the graph
: -∞ ≤ x < ∞
Domain in set notation : {x | x ∈ All real numbers}
Domain in the form interval notation : (-∞, ∞)
End behavior of the function : As both the ends of the function are downwards towards the infinity,

Tina spent 5.5 hours at the theme park. On average, she spent $8.70 each hour. How much money did she spend while at the theme park?
Answer:
[tex]\huge\boxed{$47.85}[/tex][tex]\huge\boxed{\$47.85}[/tex]
Step-by-step explanation:
We know that Tina spent 5.5 hours at the theme park. If she spend $8.70 per hour, then we can multiply 8.70 by 5.5 to find the total cost.
[tex]8.70 \cdot 5.5 = 47.85[/tex]

The answer is 7yd.
I got this answer by simply looking at the line parallel to it, which would be 16yd. I subtracted 16yd - 9yd = 7yd.

what does b equal can i please have your help
Hey there! I'm happy to help!
These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.
8x-8=5x+25
Subtract 5x from both sides.
3x-8=25
Add 8 to both sides.
3x=33
Divide both sides by 3.
x=11.
Have a wonderful day! :D
Answer:
x = 11
∠B = 80
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x - 8°
∠B = 5x + 25°
8x - 8° = 5x + 25°
8x - 5x = 25 + 8
3x = 33
x = 33/3
x = 11
plugin x into ∠B = 5x + 25°
∠B = 5x + 25°
∠B = 5(11) + 25°
∠B = 80
On a number line, the coordinates of X, Y, Z, and W are −7, −2, 2, and 7, respectively. Find the lengths of the two segments below. Then tell whether they are congruent. XY and ZW
which operation is used for the equation down below
Answer:
B
Step-by-step explanation:
2x+8=9
you want to isolate the variable so you subract 8 from both sides
2x=1
now you want x by itself so you divide by 2 on both sides
x=1/2 or x=0.5
Hope this helped :)
Point M is the midpoint of AB. The coordinates of point A are (-7, 1) and the coordinates of M are (-4,1). What are the coordinates of point B? The coordinates of point B are :
Answer:
The coordinates of point B are : (-1, 1)
Step-by-step explanation:
[tex]\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1[/tex] You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.
Then you create the equations [tex]-7 + x^{2} = -8\\1 + y^{2} = 2[/tex] you substitute -7 for +7 and add 7 to -8 which gives -1 ([tex]x^{2}[/tex]) and subtract 1 from 2 which gives you 1 ([tex]y^{2}[/tex])
To check your answer use the midpoint formula [tex]\frac{-7+-1}{2} =\frac{-8}{2} =-4\\\frac{1+1}{2} =\frac{2}{2} =1[/tex] which gives you your midpoint (-4,1)
Find k so that the distance from (–3, –1) to (k, 5) is 10 units.
Answer:
k = - 11, 5
Step-by-step explanation:
By distance formula:
[tex] \sqrt{ \{ {k - ( - 3) \}}^{2} + \{5 - ( - 1) \}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(5 + 1)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(6)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + 36 } = 10 \\ \\ (k + 3)^{2} + 36 = {10}^{2} \\ ..(squaring \: both \: sides) \\ {k}^{2} + 6k + 9 + 36 = 100 \\ {k}^{2} + 6k + 45 - 100 = 0 \\ {k}^{2} + 6k - 55 = 0 \\ {k}^{2} + 11k - 5k - 55 = 0 \\ k(k + 11) - 5(k + 11) = 0 \\ (k + 11)(k - 5) = 0 \\ k + 11 = 0 \: or \: k - 5 = 0 \\ k = - 11 \: or \: k = 5 \\ \\ \huge \red { \boxed{k = \{ - 11, \: 5\}}}[/tex]
There are two solutions for [tex]k[/tex]: 5 and -11.
In this case, we must use the Length Equation for Line Segment to solve for [tex]k[/tex], whose formula is described below:
[tex]l = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex] (1)
Where:
[tex](x_{A}, y_{A})[/tex] - Coordinates of the initial endpoint.
[tex](x_{B}, y_{B})[/tex] - Coordinates of the final endpoint.
[tex]l[/tex] - Length of the line segment.
If we know that [tex](x_{A}, y_{A}) = (-3, -1)[/tex], [tex](x_{B}, y_{B}) = (k, 5)[/tex] and [tex]l = 10[/tex], then the equation is expanded into this form:
[tex](k+3)^{2}+[5-(-1)]^{2} = 100[/tex]
[tex]k^{2}+6\cdot k + 9 + 36 = 100[/tex]
[tex]k^{2} + 6\cdot k -55 = 0[/tex]
The roots of this Second Order Polynomial are determined by Quadratic Formula:
[tex]k = 5[/tex] or [tex]k = -11[/tex].
There are two solutions for [tex]k[/tex]: 5 and -11.

Observing the histogram, frequency proportions, and normal probability plot based on the data set, below, of weights of hummingbirds (in grams) randomly selected from a population, we have a strong indication that the weights of the population of these hummingbirds from which these data were drawn are:
Answer:
Normally Distributed.
Explanation:
After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" not an answer. "correlated with a second set of data" is also wrong since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.

When we roll one die, we have a 1 in 6 probability of getting any particular number on the die. When we roll a pair of dice, there are 36 different pairs that can be produced, yet only 11 actual distinct values. Explain how the probability associated with the roll of each individual die in the pair explains the higher variability in the total outcome of the roll of each pair. How do the concepts of permutations and combinations apply to this example
Answer:
The probability of an event occurring depends on the sample space and the frequency of the event
permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6
Step-by-step explanation:
The probability of an event occurring depends on the sample space and the frequency of the event
The total outcomes of rolling a pair of fair dice would be = ( total outcome of single dice A * total outcome of single Dice B ) = 6 * 6 = 36. and this is because the Two dice are independent of each other. hence there is a higher variability in the determining the possibility of a particular number ( 1,2,3,4,5,6) showing up when a pair of dice is rolled due to the larger sample space. permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6
Find the LCM of 3 and 4
Answer:12
Step-by-step explanation:
What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1?
Answer: y= -1x - 5
Step-by-step explanation:
The equation has to be in slope-intercept form which uses the formula
y=mx+b where m is the slope and b is the y-intercept.
So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.
the x coordinate is -7 and the y coordinate is 2
2 = -1(-7) + b
2 = 7 + b
-7 -7
b = -5 the y intercept is -5
Now the equation will be y= -1x - 5
