Answer:
Step-by-step explanation:
Slope intercept form is :
y = mx + b
where m is the slope and b is the y-intercept.
So, given slope and y-intercept, all you have to do is plug in slope for m and y-intercept for b.
1.) y = 3x + 5
2.) y = 2/5x - 10
3.) y = -3/2x - 2
4.) y = 18x
5.) y = -3.253x - 14.159
For question 6, you need to calculate the slope given the two points then plug in the slope and y-intercept to get the equation.
So to find slope, you use the equation below:
slope = (y2 - y1) / (x2 - x1) = (6-0) / (0 - -2) = (6) / (2) =3
6.) y = 3x + 6
50 POINTS. A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)= -16t^2 + 64t + 4, where t is measured in seconds and h is the height in feet. What domain makes sense for this function
Answer:
The domain that makes sense for this function is all values greater than or equal to 0.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time t = 0. It is modeled by the function:
[tex]h(t)=-16t^2+64t+4[/tex]
The domain of the function is time t. The range of the function is the ball's height in the air h.
Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.
Therefore, the domain that makes sense for this function is all values greater than or equal to 0.
In interval notation, this is:
[tex][0, \infty)[/tex]
And as an inequality:
[tex]t\geq 0[/tex]

Find the area of the sector MAG in terms of Pi and approximate to the nearest hundredth
Answer:
Area of sector MAG = 35.2π unit² (Approx.)
Step-by-step explanation:
Given:
Diameter MP = 26 unit
ARC MG = ARC IP
∠GAI = 30°
Find:
Area of sector MAG
Computation:
Radius = Diameter MP / 2
Radius = 26 / 2
Radius = 13 units
∠MAG = ∠IAP
So,
∠MAG + ∠GAI + ∠IAP = 180
∠MAG + 30 + ∠MAG = 180
2∠MAG = 150
∠MAG = 75°
Area of sector = [θ/360][π][r]²
Area of sector MAG = [75/360][π][13]²
Area of sector MAG = [0.2083][π][169]
Area of sector MAG = 35.2π unit² (Approx.)
Solve the equation x^2 - 16x+ 54 = 0 by completing the square.
Fill in the values of a and b to complete the solutions.
Answer:
[tex]x = 8\±\sqrt{10[/tex]
[tex]a =8[/tex] [tex]b = 10[/tex]
Step-by-step explanation:
Given
[tex]x^2 - 16x + 54 = 0[/tex]
Required
Complete the square
[tex]x^2 - 16x + 54 = 0[/tex]
Subtract 54 from both sides
[tex]x^2 - 16x + 54 -54= 0-54[/tex]
[tex]x^2 - 16x = -54[/tex]
--------------------------------------------------
Take half of - 16
[tex](-16/2) = -8[/tex]
Square the result
[tex](-8)^2 = 64[/tex]
Add the squared result to both sides of the equation
--------------------------------------------------
So, we have:
[tex]x^2 - 16x +64= -54+64[/tex]
[tex]x^2 - 16x +64= 10[/tex]
Expand
[tex]x^2 - 8x - 8x + 64 = 10[/tex]
Factorize
[tex]x(x - 8) - 8(x - 8) = 10[/tex]
Factor out x - 8
[tex](x - 8)(x - 8) = 10[/tex]
[tex](x - 8)^2 = 10[/tex]
Take square roots
[tex]x - 8 = \±\sqrt{10[/tex]
Solve for x
[tex]x = 8\±\sqrt{10[/tex]
We have:
[tex]x = a - \sqrt{b}[/tex]
[tex]x = a + \sqrt{b}[/tex]
By comparing the above with: [tex]x = 8\±\sqrt{10[/tex]

Austin checks the temperature at 10:00 p.m. He notices if the temperature
falls by 5 more degrees, it will break the record-low temperature for that date,
which is 26 degrees.
If t = the temperature in degrees at 10:00 p.m., which mathematical sentence
expresses the information above?
O A. t-5 < 26
B. t+ 5 < 26
O C. -5 > 26
O D. t+5 > 26
Answer:
A. t - 5 < 26°
Step-by-step explanation:
Record low temperature for that date = 26°
Temperature at 10:00 PM = t
A fall in temperature by 5° = t - 5
Thus, this is said would mean the record low temperature would be breaking at this point, meaning the new temperature low recorded will be less than 26°.
In mathematical expression, this is expressed as;
t - 5 < 26°

25+30=55
55÷2=27.5
Step-by-step explanation:
median means the middle value of any set of data so first arrange the data into ascending order.
16, 25, 30, 49
the data is even so we take both the middle value , add it and divide it with 2
25+30=55
55÷2=27.5
Can someone please help me with this I will mark u brilliant
Answer:
80 is the median
The median is just the number in the middle and since 80 is in the middle the median is 80 hope that helps!
A popular internet subscription service for movies, TV series, and documentaries conducts a survey in which it randomly samples 1,000 of its customers. The survey asks the customers which way they use their streaming service the most: (1) watching movies, (2) watching TV series, or (3) watching documentaries. They also ask the level of satisfaction with the service they most often use (on a scale of 0 to 10 with 0 very poor and 10 excellent). Is there statistical evidence for this internet subscription service that the mean satisfaction differs between customers who watch movies, TV series, or documentaries the most?

The area of a parallelogram has the following formula: A=bh
Plug-in the given numbers.
Base=14cm
Height=13cm
A=bh
A=14 x 13
A=182
Therefore, the area of the figure is 182cm2
Answer: 182 square centimeters
Step-by-step explanation:
The formula for finding the area of a parrallelogram is A = bh. If the top measurement is 14 cm, then the bottom measurement is also 14 cm. The height is 13 cm.
A = (14) (13)
A = 182 cm^2
