let's say
A(-3,1) B(-3,5) C(4,1)
we need to find the perimeter of ABC for that we find each of the sides
AB BC and AC
there is a formula to find the distance between 2 poins
let's say that a point has the structure A(x1,y1) where x=-3 and y=1 and B(x2,y2) where x2=-3 and y2=5
AB=[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
AB=[tex]\sqrt{(-3+3)^2+(5-1)^2}[/tex]
AB=[tex]\sqrt{0^2+4^2}[/tex]
AB=4
we do the same thing for AC and BC
AC=[tex]\sqrt{(4+3)^2+(1-1)^2}[/tex]
AC=[tex]\sqrt{7^2+0^2}[/tex]
AC=7
BC=[tex]\sqrt{(4+3)^2+(1-5)^2}[/tex]
BC=[tex]\sqrt{7^2+(-4)^2}[/tex]
BC=[tex]\sqrt{49+16}[/tex]
BC=[tex]\sqrt{65}[/tex]
The perimeter is equal to the sum of the sides
P=AB+AC+BC=4+7+[tex]\sqrt{65}[/tex]=11+[tex]\sqrt{65}[/tex]

In how many ways can one write the numbers 1, 2, 3, 4, 5, and 6 in a row so that given any number in the row, all of its divisors (not including itself) appear to its left
Answer: 25 ways.
Step-by-step explanation:
first we have 1,2,6. this can appear once.
4, can appear in twice.
3 can appear in-between 2 and 6, this means 3 can appear 3times before 6.5 would appear 5 times.after 6 3 can appear 2 more times.[tex]= (3+2) * 5\\= 5*5\\= 25ways[/tex]
by not including itself, an appearing on the left side. one number can be written 25ways

bags. Which type of grape is most expensive?
A Green grapes
B) Red grapes
They are both the same price
Answer:
Green grapes are less expensive.
Step-by-step explanation:
5.08/2 = 2.54

Which expression is equivalent to sec2xcot?x?
O A Sin?x
O B. cScZx
OC. (1)/(cos^2x)
OD. (1)/(tan^2x)
Answer:
The equivalent expression is cosec2x
option B
Step-by-step explanation:
The correct question is ;
which expression is equivalent to sec2xcot2x?
Solution
Mathematically;
sec2x = 1/cos2x
cot2x = 1/tan2x
so we have
1/cos2x * 1/tan2x
recall that the product of tan and cos is sin
from the formula;
tan = sin/cos
so we have our final answer as;
1/sin2x
Kindly recall that ;
sin = 1/cosec
so therefore;
1/sin2x = csc2x
Circle theorems help please
Answer:
maybe 15 is the answer so
Answer:
x = 75°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended on the same arc.
The angle at the centre is
360° - (285 - x)
= 360 - 285 + x
= 75 + x
Thus
x = [tex]\frac{1}{2}[/tex] (75 + x) ← multiply both sides by 2 to clear the fraction
2x = 75 + x ( subtract x from both sides )
x = 75°

There are 40 GT students going on a field trip. Each one pays their teacher $8.75 to cover admission to the museum and lunch. Admission for the students is $120 and each one gets an equal amount to spend on lunch. How much will each GT student be able to spend on lunch?
Step-by-step explanation:
There are 40 DuBois students going on a field trip.
Each one pays their teacher $8.75 to cover admission to the museum and lunch.
Admission for the students is $120 and each one gets an equal amount to spend on lunch.
To Find :
How much will each DuBois student be able to spend on lunch.
Solution :
Amount they paid for admission :
\begin{gathered}P =\$ \dfrac{120}{40}\\\\P=\$3\end{gathered}P=$40120P=$3
Now, amount of money to spend on lunch is 8.75 -8.75−3 = $5.75 .
Hence, this is the required solution.
Answer:
Each GT student gets $3 for lunch
Step-by-step explanation:
40 GT student gave teacher $8.75 so you multiply 40 by 8.75= $350.00
To find how much they need to spend for lunch you divide $120 by 40 student because they paid for it. And you get $3!

Angela transfers 15% of each paycheck she received into her savings account. If she transferred $54 into her savings account last week, how much did she earn on that paycheck? Show your work using a model, proportion or equation
Answer:
$360
Step-by-step explanation:
Let the amount that she earned on the paycheck be represented by x
Hence,
15% of x = $54
Therefore:
15/100 × x = $54
15x/100 = $54
Cross Multiply
15x = $54 × 100
15x = $5400
x = $5400/15
x = $360
Therefore, the amount that she earned on that paycheck = $360

New grass seeds grow rapidly. A grass seed has grown to 12 millimeters tall. Tomorrow it will
be 23 millimeters tall, the next day it will be 34 millimeters tall, and on the next day it will be
45 millimeters tall. Write a rule to represent the height of the bean plant as an arithmetic
sequence. How tall will the plant be in 15 days?
A(n) = 16 + (n – 1)11; 194 millimeters
A(n) = 12 + (n – 1)11; 166 millimeters
A(n) = 13n; 195 millimeters
A(n) = 12n; 180 millimeters
Answer:
The correct answer is;
A(n) = 12 + (n-1)11; 166 millimeters
Step-by-step explanation:
Here, we want to write a rule representing the growth
From the question, we can see that the rate of growth is ;
34-23 = 23-12 = 11
This means it grows at a rate of 11 mm per day
So on the 15th day, its height will be;
We can have an arithmetic progression here, with 12 as the first term and 11 as the common difference
The nth term An can be represented as;
An = a + (n-1)d
where a = 12 mm , n = 15 and d = 11 mm
Thus, we have
An = 12 + (15-1)11
An = 12 + 154
An = 166 mm

Write the expression as an algebraic expression of x that does not involve trigonometric functions:
[tex] csc({cos}^{ - 1} x)[/tex]
Answer:
[tex]\displaystyle \csc(\cos^{-1}(x))=\frac{1}{\sqrt{1-x^2}}[/tex]
Step-by-step explanation:
Please refer to the attachment.
We have:
[tex]\csc(\cos^{-1}(x))[/tex]
First, we will let:
[tex]\cos^{-1}(x)=\theta[/tex]
Then:
[tex]x=\cos(\theta)[/tex]
So, the adjacent side of our triangle is x and the hypotenuse is 1.
Then by the Pythagorean Theorem, the opposite side is given by:
[tex]x^2+o^2=1^2[/tex]
So:
[tex]o=\sqrt{1-x^2}[/tex]
Going back, we have:
[tex]\csc(\cos^{-1}(x))[/tex]
Since arccos(x) is θ:
[tex]=\csc(\theta)[/tex]
Cosecant is the ratio of the hypotenuse over the opposite side. Therefore:
[tex]\displaystyle \csc(\theta)=\frac{1}{\sqrt{1-x^2}}[/tex]
Hence:
[tex]\displaystyle \csc(\cos^{-1}(x))=\frac{1}{\sqrt{1-x^2}}[/tex]
Select all that apply.

the area of this figure is?
Answer:
i think its 81
Step-by-step explanation:
Answer:
106 sq meters
Step-by-step explanation:
Break the figure down. I have attached an image as you can see see below.
The figure consists of three rectangles
So Area of rectangle 1 is = 4 x 7 = 28 sq meters
So Area of rectangle 2 is = 10 x 5 = 50 sq meters
So Area of rectangle 3 is = Area of rectangle 1 = 28 sq meters as they are the same rectangles
So area of the whole figure is = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Area of whole figure is = 28 + 50 + 28
Area of whole figure is = 106 sq meters.
Evaluate the expression 3r^2 if r = 1/6.
Answer:
0.08333
Step-by-step explanation:
3(1/6)^2
1/6=0.1666
1/6^2=0.02777
3*0.02777=0.08333
Answer:
1/12
Step-by-step explanation:
This is the answer because:
1) 1/6^2 = 1/36
2) 1/36 x 3 = 3/36 = 1/12 ↔ 3 ÷ 3 = 1 & 36 ÷ 3 = 12 = 1/12
Therefore, the answer is 1/12.

Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answer:
The polynomial is ;
x^3 -2x^2 -13x - 10
Step-by-step explanation:
Given the zeros, we set them to equal zero so as to get the linear factors
Mathematically, that will be as follows;
x = -2
x + 2
x = 5
x-5
x = -1
x + 1
So we have the polynomial as;
(x + 1)(x + 2)(x-5)
= (x -5)(x^2 + 3x + 2)
= x^3+ 3x^2 + 2x -5x^2 -15x - 10
= x^3 -2x^2 -13x - 10
The average time a human being can hold their breath underwater is 1 minute. A hippo can hold its breath underwater for at least 5 times as long as a human. Write an inequality that represents how long a hippo can hold its breath underwater.
Answer:
Average breath hold time by hippo under water ≥ 5 minutes
Step-by-step explanation:
Average time by human = 1 minute
Average time by hippo = ≥ 5 times human
Since average human breath hold time = 1 minute
Average breath hold time by hippo = 5 * 1 minute
Average breath hold time by hippo under water ≥ 5 minutes
