Question 4 A triangle has two sides that are 8 cm and 13 cm. What could be the length of the triangle's third side? Select three that apply. А 5 cm B 10 cm С 17 cm D 20 cm E 21 cm F 24 cm
know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8
You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?
Answer:
6 x 4 = 24 x $2 = $48
Step-by-step explanation:
The total cost of the rectangular frame is C = $240.
What is rectangle?A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,
We need to find the total cost of framing material
The perimeter is given by:
P = 2x(L + W)
In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:
P = 2x(6in + 14in)
P = 2x20in = 40in
Since, the framing material costs $6 per inch, then the total cost of the frame will be:
cost = 40x$6 = $240

How many terms are in the expression 2a - c + 7d+ 15
Answer:
8c
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
I just want to tell you what a term is because your going to really need it when you go into middle school. So a term is where there is a number or a a number with a variable with it or a variable by itself. For example if there is 4x + 6m + 3 + X you would have 4 terms because you have 4 numbers along with variables and a variable by itself and with some numbers which are Co -Efficient. Co-Efficient is when a number is with a variable the number along with the variable is called a Co-Efficient. Both of them together is called a term so now you know :) The whole equation is called an expression if a a number is by itself like 4 + 3m the 4 would be considered as a constant because its just a normal number standing by itself.

What is the domain of y = tan x? A. (–∞, ∞) B. C. all D. all
Given:
The function is
[tex]y=\tan x[/tex]
To find:
The domain of the given function.
Solution:
We know that, domain is the set of x-values or input values.
We have,
[tex]y=\tan x[/tex]
[tex]y=\dfrac{\sin x}{\cos x}[/tex]
The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.
So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
Note: All options are incorrect.
Answer:
C
Step-by-step explanation:
all x≠pi/2+pi n

Answer:
x = 119, y = 55
Answer:
x = 119°
y = 55°
Step-by-step explanation:
y + 125 = 180 {linear pair}
y = 180 - 125
y = 55°
Sum of all the angles of quadrilateral = 360
x + 55 + 72 +114 = 360
x + 241 = 360
x = 360 - 241
x = 119°

Answer:
-33 and -21
Step-by-step explanation:
-36, -33, -30, -27, -24, -21, -18
-36
-36 + 3 = -33
-33 + 3 = -30
-30 + 3 = -27
-27 + 3 = -24
-24 + 3 = -21
-21 + 3 = -18

1. What is the domain of the function graphed on the grid?
Answer:
[-2,4]
Step-by-step explanation:
The domain is just asking for all the possible x values
we can see that the lowest x value is -2 and the highest is 4 which means our answer is
[-2,4]
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the
x
-axis. The range is the set of possible output values, which are shown on the
y
-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.
We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

What two numbers multiply to -24 and add to -5?
The two numbers that multiply to -24 and add to -5 are 3 and -8
How to determine the numbersFrom the question, we have the following parameters that can be used in our computation:
Product = -24
Sum = -5
Let the numbers be x and y
So, we have
xy = -24
x + y = -5
Let x be 3 and y be -8
So, we have
3 * -8 = -24
3 - 8 = 5
The above equations are true
Hence, the numbers are 3 and -8

A school district currently has 12,000 students. Based on declining enrollment figures, the number of students in the school district is expected to decline by 5% each year. Which of the following functions represents the number of students, S, in the school district after n years?
Answer:
S(n) = 12,000(–0.05)n
Step-by-step explanation:
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
Original population , P = 12000
Rate of decline, r = 5%
r = 5/100
r = 0.05
The number of years = n
The population of students after n years will be given by the formula:
[tex]S =P(1-r)^n[/tex]
Substitute r = 0.05 and P = 12000 into the formula above
[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
