Answer:
5 | 20
3 | 12
4 | 16
Step-by-step explanation:
y = 4x so just multiply each x value by 4 to get the y value
Answer:
X | Y
5 | 20
3 |12
4 |16
Step-by-step explanation:
What they actually means is
y=4x
So when x is 5, what is y? So u just change x to 5, since they told u x is 5
And same for the others
Help please and thanks
Answer:
x = 7
Step-by-step explanation:
Because the points are collinear:
AB + BC = AC
We'll plug in the expressions in terms of x.
(-1 + 2x) + (11) = (3x + 3)
And solve for x. Combine like terms on the left
2x + 10 = 3x + 3
Subtract 3 on both sides
2x + 7 = 3x
Subtract 2x on both sides
7 = x
5-81. Scientists hypothesized that dietary fiber would impact the blood cholesterol level of college students. They collected data and found r = -0.45 with a scattered residual plot. Interpret the scientists' findings in context. Hint: r stands for correlation coefficient)
Step-by-step explanation:
It shows that the content of dietary fiber is negatively correlated to the blood cholesterol of college student, as the correlation coefficient is negative. However, the r=-0.45 shows the two factors are lowly correlated (absolute value of r between 0.3 and 0.5)
Find the missing length. The triangles are similar.
Answer:
182
Step-by-step explanation:
First, we can say that ∠ACB and ∠BCF are opposite angles because they are not next to each other and are formed by intersecting lines. Therefore, ∠ACB = ∠BCF
Next, angles correspond with the side opposite of it. This means that, for example, ∠ACB corresponds with line AB and ∠BCF corresponds with line BF. Because ∠ACB and ∠BCF are equal and the triangles are similar, we can say that their corresponding sides have a ratio with each other. Similarly, ∠CAB corresponds to CB, ∠ABC corresponds to AC, ∠CWV corresponds to CV, and ∠CVW corresponds to CB.
Because the triangle CVW is isosceles, we can say that the angles whose corresponding sides are equal are equal as well, so ∠CAB = ∠ABC and ∠CVW = ∠CVW. Next, because ∠ACB and ∠BCF are equal and correspond to each other, and the other two angles in each triangle are equal to each other, we can say that the other two angles must be equal. Another way of putting this is like this:
Say that x = ∠CAB. Then,
∠CAB + ∠ABC + ∠ACB = 180
x + x + ∠ACB = 180
2x + ∠ACB = 180
subtract ∠ACB from both sides
180 - ∠ACB = 2x
Similarly, if y = ∠CWV,
180 - ∠WCV = 2y. Therefore, 2y=2x and y=x, so ∠CAB = ∠ABC = ∠CWV = ∠CVW.
Given this, we can say that sides CV and CW correspond with BC and AC. This means that the ratio between, for example, CV and BC is equal to the ratio between CW and AC. Therefore,
CV/BC = CW/AC

Solve the following equation on the interval (0,2π)
cos2x=cosx
Answer:
x = 0, 2π/3, 4π/3, 2π.
Step-by-step explanation:
cos 2x = 2cos^2x - 1 so
2cos^2x - 1 = cos x
2cos^2x - cos x - 1 = 0
(2cosx + 1)(cos x - 1) =0
cos x = -1/2, 1.
When cos x = 1, x = 0, 2π
when cos x = -1/2, x = 2π/3, 4π/3.

In the figure, M and N are midpoints of RT and ST. What is the length of MN
Answer:
b - a
Step-by-step explanation:
Given M and N are midpoints, let's find the coordinates of the midpoints first. Then we can use that information to find the length
The midpoint formula is
( (x1 + x2)/2, (y1 + y2) / 2 )
So M = ( (2a + 2c)/2, (0 + 2d)/2 ) = (a + c, d)
And N = ( (2c + 2b)/2, (2d + 0)/2 ) = (c + b, d)
Because the y-coordinates are the same (d), the distance from M to N is,
final x-coordinate minus initial x-coordinate
x-coordinate of N minus x-coordinate of M
(c + b) - (a + c)
Distribute the negative and remove the parentheses
c + b - a - c
Group the cs together
c - c + b - a
Cancel out the cs

Answer: 7/64 inch is bigger by 1/64 inch difference
Step-by-step explanation:
STEP ONE: Convert the denominators into Least Common Multiple (LCM)
LCM of 32 and 64:
First 3 multiples of 32: 32, 64, 96
First 3 multiples of 64: 64, 128, 192
Since 64 overlaps in both terms, 64 is the LCM of 32 and 64.
STEP TWO: Convert the fractions
3/32 = (3 × 2) / (32 × 2) = 6/64
7/64 = 7/64
STEP THREE: Compare the numerator to define the size of fractions
6 < 7, therefore, 6/64 < 7/64
7/64 - 6/64 = 1/64 inch
Hope this helps!! :)

Garcy has 4/5 pound of bird seed she needs 3/10 pound to feed the birds daily which rectangle models below shows how many days worth
Answer:
I believe it is 2 days
Step-by-step explanation:
3/10 can be simplified into 1.5/5 and just go up by the 1.5/10 of a pound she needs each day. if she did it for 3 days she would need 4.5/5 so she has enough for 2 days
This is a high school grade question
Answer:
[tex]herre \: total \: angle \: in \: circle = 360 \\ then \\ \: 6x + 1 + x - 19 + 35 = 360 \\ 7x - 18 + 35 = 360 \\ 7x + 17 = 360 \\ 7x = 343 \\ x = \frac{343}{7} = 49 \\ x = 49degree \\ thank \: you[/tex]
6x + 1° + x - 19° + 35° = 360°
6x + x + 1° - 19° + 35° = 360°
7x + 1° - 19° + 35° = 360°
7x + (-18)° + 35° = 360°
7x + 17° = 360°
7x = 360° - 17°
7x = 343°
x = 343° : 7
x = 49°

pls answer fasttt
Answer:
2
Step-by-step explanation:
first multiply everything by 6 to get rid of the fractions
then we get 5m-4 -6 = 24m -9m -30
simplify the equation 5m-10=15m-30
subtract 5m from both sides and add 30 to both sides 10m=20

if m<8= 23° find each measure.
straight angles ( 1 , 2 , 3 , 4 ) parallel to straight angles Angles ( 5 , 6 , 7 , 8 )
m<8 = m< 6 = 23° [ Opposite angles]
m< 4 = m< 2 = 23°
m<8 + m< 5 = 180°
23° + m< 5 = 180°
m<5 = 180 - 23 = 157
m< 5 = m< 7 = 157° [ Opposite angles]
m< 1 = m< 3 = 157° [ Opposite angles]
straight angles ( 1 , 2 , 3 , 4 ) parallel to straight angles Angles ( 5 , 6 , 7 , 8 )
So;m< 1 = 157m< 2 = 23m< 3 = 157m<4 = 23m< 5 = 157m< 6 = 23m< 7 = 157m< 8 = 23I hope I helped you^_^

a mother is presently four times as old as her daughter if the sum of their ages 6 years ago was 48 find their present ages
i need this answer with explanation
ASAP plzzzzzzz
Answer:
Daughter is 12 and mother is 48.
Step-by-step explanation:
Let the daughters age be x years now then the mothers age is 4x.
6 years ago the daughter was x-6 years and the mother was 4x - 6.
So we have the equation:
x - 6 + 4x - 6 = 48
5x - 12 = 48
5x = 60
x = 12
So the daughter is 12 and the mother is 4*12 = 48.
A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 640t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit
Answer:
20 seconds
Step-by-step explanation:
h(t) = -16t2 + 640t
to find the maximum value =>
h'(t) = 0
-32t + 640 = 0
-32(t -20)= 0
t-20 = 0
t = 20 seconds
Find derivative of h(t)

How does the graph of f(x) = (x – 9)^4-3 compare to the parent function g(x) =x^4?
Answer:
Step-by-step explanation:
The child graph is shifted 9 units to the right. That's what the nine does. The graph also shifts 3 units down when compared to g(x).
I have put a graph in so that you can see the shifts for yourself.
The red line is g(x) = x^4
The blue line is f(x) = (x - 9)^4 - 3
