Given the function f(x) = 0.65x + 117, what
s the x-value of the zero?
Answer:
x = -180
Step-by-step explanation:
0 = 0.65x + 117
-117 = 65x/100
cross-multiply to solve for 'x':
65x = -11700
x = -11700/65
x = -180

Find the vertex of the parabola y = x2 - x + 5.
Simplify both coordinates and write them as proper fractions, improper fractions, or integers.
Answer:
(1/2, 19/4)
Step-by-step explanation:
So the formula is y=-b/2a.
a= 1
b= -1
Plug in the values to get x=1/2.
you then plug in 1/2 to get the y
you end up with 19/4.
Your vertex ends up as (1/2, 19/4).
hope this helped!!
Hey I need help, what is the area of this!
Answer:
12 cm^2
Step-by-step explanation:
Here the base and height of a triangle are given. To find the area, we use the formula A = (1/2)(base)(height), which here is
A = (1/2)(8 cm)(3 cm) = 12 cm^2

Answer:
[tex] \displaystyle PW = \underline{ \quad18 \quad}[/tex]
Step-by-step explanation:
by tangent property we acquire:
[tex] \displaystyle 3x - 6 = x + 10[/tex]
add 6 to both sides:
[tex] \displaystyle 3x= x + 16[/tex]
cancel x from both sides:
[tex] \displaystyle 2x= 16[/tex]
divide both sides by 2:
[tex] \displaystyle x= 8[/tex]
so,
[tex] \displaystyle PW = 3x - 6[/tex]
plug in the got value of x:
[tex] \displaystyle PW = 3.8 - 6[/tex]
simplify multiplication:
[tex] \displaystyle PW = 24- 6[/tex]
simplify Substraction:
[tex] \displaystyle PW =18[/tex]
hence, The measure of PW is 18 unit

The measurement of a central angle is θ=240 degrees. Find the measurement of θ in radians.
Answer:
4.189 radians
Step-by-step explanation:
Given data
θ=240 degrees
Let us convert from degrees to radians
Angle in Radian= Angle in degree* π/180
Substitute
Angle in Radian= 240* π/180
Angle in Radian= 4* π/3
Angle in Radian= 4* 3.142/3
Angle in Radian=12.568/3
Angle in Radian=4.189 radians
Which option shows the measure of the unknown angle,x and how to find it
Answer:
E) 37
Step-by-step explanation:
The total measurement for the angle ABC is 90 as it is a right angle.
Add your known angles together and substract from 90 to get your unknown.
90 - 21 - 32 = 37
Answer:
E. Subtract 21 and 32 from 90, x=37
Step-by-step explanation:
Since there are 90 degrees in a right angle, we can find the missing angle by adding the two angles we have together and then subtracting the sum from 90.

w² + 9 − 2 −18
Step 2:
Common factor from the two pairs
w²+ 9 − 2 − 18w
( w+ 9) − 2( w+ 9)
Step 3:
Rewrite in factored form
(w + 9) − 2( w+ 9)
(w−2)(w+9)
Solve for the missing side. Your answer should be in simplest radical form.

which statement describes the effect on the parabola y= x^2 -1 when its is changed to y =x^2 +6?
The effect on the parabola y = x^2 - 1 when it is changed to y = x^2 + 6 is a translation of 7 units upwards.
What is the effect on the parabola?First let's do an introduction, for any function f(x), we can define a vertical translation of N units as:
g(x) =f(x) + N
Where if N > 0, the translation is upwards, and if N < 0, the translation is downwards.
In this case, we start with the parabola:
y = f(x) = x^2 - 1
Now we know that the transformed function is:
y = g(x) = x^2 + 6
Now, notice that if we apply a translation upwards of 7 units of the original function we will get:
y = f(x) = x^2 - 1 + 7 = x^2 + 6
We got the transformed function.
Then the effect on the parabola is a translation of 7 units upwards.

A. 0.09
B. 0.12
C. 0.22
D. 0.35
Answer:
its A
Step-by-step explanation:
The probability that a person consumes 2,000 to 2,500 calories in a day is 0.22.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that:
Weight/Calories 1000-1500 1500-2000 2000-2500 Total
per Day
120 lb. 90 80 10 180
145 lb. 35 143 25 203
165 lb. 15 27 75 117
Total 140 250 110 500
Hence, Total no. of person consumes 2000 to 2,500 calories in a day = 110
And, Total = 500
Now the probability that a person consumes 2,000 to 2,500 calories in a day :
⇒ 110 / 500
⇒ 0.22
Hence the probability that a person consumes 2,000 to 2,500 calories in a day is 0.22.

Which choice correctly describes this event? Every time I flip a coin / will get tails.
A)Certain
B)Impossible
C)Likely
D)Unlikely
Please help ASAP ill give BRAINLIEST
Answer:
D
Step-by-step explanation:
With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.
A is incorrect as it is possible to land heads on any flip.
B is incorrect as there is always a possibility of landing tails on every flip.
C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.
Hence D is the answer.
Karen and her friends decided to have a water balloon fight! They got 20 water balloons and used 6 liters of water to fill them all equally. How much water was in each balloon?
Answer:
Amount of water in each balloon = 300 milliliter
Step-by-step explanation:
Given:
Amount of water used in balloon = 6 liter
Number of water balloon = 20 balloon
Find:
Amount of water in each balloon
Computation:
Amount of water used in balloon = 6 x 1000
Amount of water used in balloon = 6,000 milliliter
Amount of water in each balloon = Amount of water used in balloon / Number of water balloon
Amount of water in each balloon = 6,000 / 20
Amount of water in each balloon = 300 milliliter

Angle bisector theorem states that "angle bisector of an angle divides the opposite side into two segments which are proportional to the other two sides of the triangle."
By applying this theorem in the given ΔABC,
AD is the angle bisector of ∠CAB which divides the opposite side of the angle into two segments BD and CD.
Therefore, [tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]
[tex]\frac{5.1}{4}=\frac{AC}{4.3}[/tex]
[tex]AC=\frac{5.1\times 4.3}{4}[/tex]
AC = 5.4825
AC ≈ 5.5 units
A spinner has 6 equally divided sections labeled A, B, C, D, E and F. After spinning the spinner, a number cube is rolled. What is the probability that the spinner will land on a consonant and the number cube will land on a number greater than 2?
Answer: [tex]\dfrac{2}{9}[/tex]
Step-by-step explanation:
Given
The spinner has 6 equal sections A, B, C, D, E, and F
The two events occurred one after the other. So, the probability is the product of the probabilities of each event.
There are two consonants in the given 6 letter
The probability of landing over a consonant is
[tex]P_1=\dfrac{2}{6}[/tex]
The number greater than 2 in a cube are 3,4,5,6
So, probability corresponding to it
[tex]P_2=\dfrac{4}{6}[/tex]
So, the required probability is
[tex]\Rightarrow P=P_1\times P_2\\\Rightarrow P=\dfrac{2}{6}\times \dfrac{4}{6}\\\\\Rightarrow P=\dfrac{8}{36}\\\\\Rightarrow P=\dfrac{2}{9}[/tex]

Sixteen percent of videos are shorter than what
length?
The graph shows the distribution of the lengths (in
seconds) of videos on a popular video streaming site.
The distribution is approximately Normal, with a mean
of 264 seconds and a standard deviation of 75
seconds.
O 39 seconds
O 114 seconds
O 189 seconds
O 339 seconds
Streaming Videos
Answer:
189 seconds
Step-by-step explanation:
16% shorter,
Left side first and second group is 2.5% and 13.5% = 16%
189 is the max of that group
16% of videos on the streaming site are shorter than 189 seconds.
To determine the length at which 16% of videos are shorter, we can use the properties of a normal distribution.
Given that the mean length is 264 seconds and the standard deviation is 75 seconds, we can use a Z-score to find the corresponding percentile.
First, we need to find the Z-score associated with the 16th percentile. This can be done using a Z-table or a statistical calculator. The Z-score corresponding to the 16th percentile is approximately -0.9945.
Using the formula for Z-score:
Z = (X - μ) / σ,
where X is the length of the video, μ is the mean, and σ is the standard deviation, we can rearrange the formula to solve for X:
X = Z * σ + μ.
Substituting the values:
X = (-0.9945) * 75 + 264,
X ≈ 189 seconds.
Therefore, approximately 16% of videos on the streaming site are shorter than 189 seconds. So, the correct answer is 189 seconds.
