Answer:
Not a right triangle
Step-by-step explanation:
We can figure out if it is a right triangle or not by using the pythagorean theorem.
a^2 + b^2 = c^2
In this case a and b are 16 and 18
In order for it to be a right triangle, c has to equal 34, in this problem.
16^2 + 18^2 = c^2
= 580^2
= [tex]\sqrt{580}[/tex] = 24.0832
Since 24.0832 does not equal 34, this is not a right triangle

Which statements about the graph of the function f(x) =2x^2 - x - 6 are true? Select two options.
The domain of the function is {xlx > 1/4}
The range of the function is all real numbers.
The vertex of the function is (1/4, -6 1/8).
The function has two x-intercepts.
The function is increasing over the interval (-6 1/8, ).
we have
using a graphing tool
see the attached figure
This is a quadratic equation (vertical parabola) open up
The vertex is a minimum---------> Vertex
The domain of the function is all real numbers-------> interval (-∞,∞)
The range of the function is the interval----------> [-6.125,∞)
The function has two x-intercepts-----> and
The function is increasing over the interval-----> (0.25,∞)
The function is decreasing over the interval-----> (-∞,0.25)
Answer:
the range of function is all real numbers,
and the function has 2 x intercepts
Step-by-step explanation:
super easy way to do it, look for an i in your equation, if there is none, and you dont take the square root of a negative number, all answers are real. then you can see that you function crosses the x-axis twice, meaning you have two x-intercepts
(50 points) Write an equation for the sine waves.
Answer:
It started from the Origin(Sine graph). It curved upwards immediately it started... Meaning graph's amplitude is gonna be positive one
The Equation for a sine graph is ASin[B(x-C)] + D
A=Amplitude
B= 2π/period
C= c value at the starting point.
D= y value at starting point
Let your Starting point be at the sinusoidal axis (Max + Min)/2.
Looking at this graph
Let's take 1cm on the y axis to be 1unit(1,2,3,4...)
On the x axis... let's take 1cm to be π units(π,2π,3π....)
To get the sinusoidal axis Max - Min/2
Since 1cm is 1unit
Max =1 (from the graph)
Min= -1
1-1/2 = 0
The axis is at the center of middle
Meaning
D=y=0(Its directly at the x axis)
From this axis at the origin... The graph goes... Intercept Maximum... intercept Minimum... Meaning its a Positive sine graph.
A=amplitude = 1cm
B=Period...(Time to complete one Oscillation)
It doesn't fall directly on an x value... It falls at the 1.9th position. or 19/10
B=2π/Period.
B=2π/19/10
B=2π x 10/19
B=20π/19
C=0
Writing the Equation
Y= 1Sin[20π/19(x-0)] +0
ie
Y = Sin [20πx/19]
My thoughts on it
Correct me if wrong... Thanks
the area of a square is 225cm². On the map drawn to scale 1 : 3 find the area of the square
Answer:
25 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Area if a square = length²
225 = length²
length = √225
length = 15
if the map is drawn to scale of 1 : 3
the length on the map = 15/3 = 5
area of the square 5 x 5 = 25

Answer:
39.1
Step-by-step explanation:
31.7 + 42.8 + 26.4 = 100.9
35 times 4 = 140
140 - 100.9 = 39.1
Answer:
[tex]mean = \frac{31.7+42.8+26.4+x}{4} \\\\35 = \frac{31.7+42.8+26.4+x}{4} \\\\\\35*4 = 31.7+42.8+26.4+x \\\\140 = 100.9 + x\\\\x= 39.1[/tex]

24 cm^2
Step-by-step explanation:
The base of ∆Z is 4 cm, and its height is 12 cm. The area is given by the formula ...
A = 1/2bh
A = 1/2(4 cm)(12 cm) = 24 cm^2 . . . area of Z
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books. What is the probability one of them is mathematics and other two are either physics or history books
Answer:
Probability that one of them is mathematics and other two are either physics or history books = 0.51
Step-by-step explanation:
Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
To find - What is the probability one of them is mathematics and other two are either physics or history books ?
Solution -
Given that,
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
So,
Total number of books = 3 + 3 + 1 = 7
The student has to select 3 books
So, Total number of ways = [tex]^{7} C_{3}[/tex] = 35
So,
Probability that one of them is mathematics and other two are either physics or history books is -
= [tex]\frac{^{3} C_{1}. ^{4} C_{2} }{^{7} C_{3}}[/tex]
= [tex]\frac{(3)(6)}{35}[/tex]
= [tex]\frac{18}{35}[/tex]
= 0.51
⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51
Dayquan decided to run some laps around the track. If the diameter of the track is 75 feet, how far around the track did he run?
Answer: 235.5 feet
Step-by-step explanation:
In this case, we have to calculate the circumference of the track. The circumference will be calculated as:
= 2πr
Diameter = 75 feet.
Radius = 75/2 = 37.5 feet
Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet

Carmen wants to join a gym. Gym A costs $26.76 plus an additional $4 for each visit. Gym B has no initial fee but costs $12.92 for each visit. After how many visits will both plans cost the same?
Answer:
After 3 visits both plans will cost the same.
Step-by-step explanation:
Gym A costs $26.76 plus an additional $4 for each visit.
Gym B has no initial fee but costs $12.92 for each visist.
The cost for gym A can be written as
C= $26.76 + 4(x) where x is the number of visits to the gym A
The cost for gym B can be written as
C= $12.92 (x) where x is the number of visits to the gym B
Both costs will be equal
12.92x= 26.76 +4x
12.92x-4x= 26.76
8.92x= 26.76
x= 26.76/8.92
x= 3
after 3 visits both plans will cost the same.
Check
12.92x= 26.76 +4x
12.92*3= 26.76 +12
38.76= 38.76
Somebody please help.
A national health organization warns that alcohol use among middle school students is on the rise. Concerned, a local health agency randomly and anonymously surveys 110 of the middle school students in its city. 21 of them report having been intoxicated. Create a 90% confidence interval. Find p-hat. (p -hat = x/n)
Answer:
CI 90 % = [ 0,05 ; 0,16 ]
Step-by-step explanation:
From sample we got
n = 110
x = 21
p = 21/110 = 0.19 then q = 1 - p q = 1 - 0.19 q = 0.81
To create a 90 % confidence Interval, the significance level α = 10 %
α = 0.1 α/2 = 0.05
t(c) for α/2 = 0.05 is from z-table z(c) = 1.64
CI 90 % = ( p ± z(c) * √(p*q)/n
CI 90 % = [ 0,11 ± 1.64 * √ (0.19*0.81)/110 ]
CI 90 % = [ 0.11 ± 1.64 * 0.037 ]
CI 90 % = [ 0.11 ± 0,06 ]
CI 90 % = [ 0,05 ; 0,16 ]

C. the figure:
By using Pythagoras law
base[b]=AB=perpendicular [p]=AC
hypotenuse [h]=BC
we have
h²=p²+b²
substituting value
([tex] 4\sqrt{5} [/tex])²=2p²
16*5=2*([tex] 2\sqrt{10} [/tex])²

The scatterplot below represents the number of hot drinks sold on a given
day versus the low temperature of that day. Of the following lines, which
best fits the data in the scatterplot?
Answer:
A) y=-1/2x+55
Step-by-step explanation:
We can clearly see a negative trend/association between the number of hot drinks sold on a given day and the low temperature of that day. Therefore, the slope of the best line of fit must be negative, eliminating D and E. Also, notice that when the low temperature is 0°F, the number of hot drinks sold is about 55, which is a good indicator of our y-intercept or constant, eliminating choice C. Because the best line of fit is not so steep, the slope will be closer to 0 if it's a negative trend. This eliminates choice B, making the correct answer A.
Find the slope of the line passing through the points (-9, -6) and (-4, 5).
