Answers:
a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'=========================================================
Explanations:
a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.Find the value of x
Use sin, cos, or tan
=========================================================
Explanation:
We use cosine to tie together the adjacent and hypotenuse
cos(angle) = adjacent/hypotenuse
cos(38) = x/21
21*cos(38) = x
x = 21*cos(38)
x = 16.5482258257411
x = 16.5

−5520x³
step by step explanation:
15 x ( − 16 ) x ( − 23 ) x ( − 1 )
= 15 * x * ( − 16 ) * x * ( − 23 ) * x * ( − 1 )

find the measure of the exterior angle.
Answer:
110°
Step-by-step explanation:
t+(t+10)+(t+20)=180
t+t+10+t+20=180
3t=180-10-20
3t=150
t=50°
t+20=50+20
=70
180-70=110°
What is the 6th term of the geometric sequence?
3,6, 12, 24, ...
A. 36
B. 27
C. 48
O D. 96
Answer:
96 is the 6th term of the geometric sequence
Step-by-step explanation:
The sequence is just adding the number twice to get the nect sequence.
So,
3+3 = 6
6+6 = 12
12+12 = 24
24+24 = 48
48+48 = 96 this is the 6th term

When an object is dropped from a tall building, it falls about 16 feet in the first second, 48 feet in the second second, and 80 feet in the third second, regardless of its weight.
How many feet would an object fall in the tenth second?
Answer:
the object will fall 5060 feet in 10 second.
Step-by-step explanation:
g= 9.8m/s^2 and 9.8×3.33=32.67 feet/s^2.
initial velocity (u)= 16 feet/second
time taken(t)=10 second
final velocity(v)= ?
now,
V= u+ GT
=16+32.67×10
=342.67feet/second
again
distance covered= VT+1/2gt^2
=342.67×10+1/2×32.67×100
=3426.7+1633.33
=5060 feet

Step-by-step explanation:
The number of solution of the equation - 3x + 12 - 9x + 8 = -3(4x - 7) will be infinite many solutions.
What is the solution to the equation?In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.
The equation is given below.
-3x + 12 - 9x + 8 = - 3(4x - 7)
Simplify the equation, then we have
- 3x + 12 - 9x + 8 = -3(4x - 7)
- 12x + 20 = - 12x + 21
12x - 12x = 1
(0) x = 1
The number of solution of the equation - 3x + 12 - 9x + 8 = -3(4x - 7) will be infinite many solutions.

For this data set, there is an outlier. The outlier is four.
This is representing a small number of assignments required in math class that month.
This means that the correct answer is B.
Answer:
B
Step-by-step explanation:
The answer should be B or the second choice because the number 4 is unusually low compared to the rest of homework assignments given in the other math classes for that month. I made a graph to show how the number 4 is not near the number of homework assignments given in the other math classes.

A population has a standard deviation of 25.29. What is the approximate standard error of the mean for a sample size of 175?
The answer is 1.91 but can someone show me how they got that answer?
Will mark brainliest
Answer:
Standard error of the mean: 1.91
Step-by-step explanation:
The standard error of a sample mean is [tex]SEM=\frac{\sigma}{\sqrt{n}}[/tex] where [tex]\sigma[/tex] is the sample standard deviation and [tex]n[/tex] is the sample size. Therefore, the standard error of the mean for a sample size of 175 is [tex]SEM=\frac{\sigma}{\sqrt{n}}=\frac{25.29}{\sqrt{175}}=1.911744304\approx1.91[/tex]

Step-by-step explanation:
Jayden is going to see a movie and is taking his 3 kids. Each movie ticket costs $12 and there are an assortment of snacks available to purchase for $3 each. How much total money would Jayden have to pay for his family if he were to buy 4 snacks for everybody to share? How much would Jayden have to pay if he bought xx snacks for everybody to share?
Answer: Total price to pay with 4 snacks = $48
Total price to pay with x snacks =36+3x
Step-by-step explanation:
Given: Jayden is going to see a movie and is taking his 3 kids.
Each ticket cost = $12
Cost of all tickets = 3 x $12
= $36
Price for each snack = $3
Price for 4 snacks = $3 x 4
= $12
Total price to pay = Cost of all tickets + price of all snacks
Total price to pay with 4 snacks = $(36+12)
= $ 48
Price for x snacks = $3x
Total price to pay with x snacks =36+3x

what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)

Answer:
[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]
Step-by-step explanation:
Part A:
The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].
What we're given:
[tex]b[/tex] of 9.2[tex]h[/tex] of 4.5Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]
Part B:
The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]
Part C:
The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].
What we're given:
[tex]b[/tex] of 0.4[tex]h[/tex] of 0.5Substituting given values, we get:
[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]
2x - 5y = 5
x + y =2
Solve the system of equations
Answer:
[tex]{ \bf{2x - 5y = 5 - - - (a)}} \\ { \bf{x + y = 2 - - - (b)}} \\ (a) - 2(b) : \\ - 7y = 1 \\ y = - \frac{1}{7} \\ x - \frac{1}{7} = 2 \\ x = \frac{15}{7} [/tex]
Answer:
[tex]x = \frac{15}{7} , \ y = - \frac{1}{7}[/tex]
Step-by-step explanation:
2x - 5y = 5 ---------- ( 1 )
x + y = 2 ------------ ( 2 )
x = 2 - y ---------( 3 )
Substitute x in ( 1 ) :
2( 2 - y) - 5y = 5
4 - 2y - 5y = 5
- 7y = 5 - 4
-7 y = 1
[tex]y =- \frac{1}{7}[/tex]
Substitute y in ( 2 ) :
[tex]x + y = 2\\\\x -\frac{1}{7} = 2\\\\x = 2 + \frac{1}{7}\\\\x = \frac{14 + 1}{7}\\\\x = \frac{15}{7}[/tex]
solve the quadratic equation below for the exact values of x.
