First of all this is a very poor question, and you should question it a bit. What are these figures? Are they regular? (first 2). Is the last one a parallelogram. I'm going to assume that the yellow one is a rectangle and the middle one is a pentagon and the last one is a parallelogram.
Yellow
A has 4 right angles (That's the property of a rectangle).
Green
B has 5 angles that are equal to 108 degrees. If you draw a 2 lines from any vertex you get 3 triangles. The size of the interior angles totals 3 triangles * 180 degrees = 540 degrees.
540/3 = 108.
Each angle in the interior is 108 degrees.
B has 5 angles all equal 108 degrees. All 5 are obtuse.
Red
Just by sight and assumption C has 2 obtuse angles, and 2 acute angles.
How Would You Guys Describe A "Function Notation"?
Hey there!
When you write an equation in function notation, one side of the equation is, "f(x)".
You can replace x with another variable such as n if you are using a different one.
f(x) takes the place of y in an equation.
For example, the equation y = 3x + 2 in function notation is f(x) = 3x + 2.
Hope this helps!
what is the slope of 2x+3y=15
Note that the slope-intercept form is: y = mx + b
First, set the equation as such
2x (-2x) + 3y = (- 2x) + 15
3y = -2x + 15
Isolate the y. Divide 3 from both sides
(3y)/3 = (-2x + 15)/3
y = (-2/3)x + 5
-2/3 is your slope

d+(−5.004)=2.826
I am so confused. What do I do?
Okayyy, so the answer is 7.830. Adding a negative number is the same as subtracting a positive number so you can rewrite it as d-5.004=2.826, then you will add 5.004 to 2.826 and for your answer you will get 7.830.
Answer:
d=7.83
Step-by-step explanation:
Do the following
d +(-5.004)=2.826
1) To eliminate the Parenthesis we're going to operate the plus times -5.004:
What gives us:
d - 5.004 = 2.826
2) Let's add 5.004 to both sides to leave d alone, on ther first member:
d-5.004 +5.004= 2.826+5.004
d+0=7.830
d=7.83

A particle moving along the x axis so that it’s position at t is greater than or equal to 0 is given by s(t)=(t)ln(3t). Find the acceleration of the particle when the velocity is first zero.
We are given
equation of position
[tex]s(t)=(t)ln(3t)[/tex]
Calculation of velocity:
we can find derivative
[tex]s'(t)=1*ln(3t)+t*\frac{3}{3t}[/tex]
[tex]s'(t)=ln(3t)+1[/tex]
so, velocity is
[tex]v(t)=ln(3t)+1[/tex]
now, we can set it to 0
and then we can solve for t
[tex]v(t)=ln(3t)+1=0[/tex]
[tex]t=\frac{1}{3e}[/tex]
Calculation of acceleration:
we can find derivative again
[tex]v'(t)=\frac{3}{3t} +0[/tex]
[tex]v'(t)=\frac{1}{t} [/tex]
so, acceleration is
[tex]a(t)=\frac{1}{t} [/tex]
now, we can plug value of t
[tex]a(\frac{1}{3e})=\frac{1}{\frac{1}{3e}} [/tex]
[tex]a(\frac{1}{3e})=3e [/tex]..................Answer
Expressed as a product of its prime factors in index form, a number N is
N=3 X 5^2 X x^3
Express 5N^2 as a product of prime factors in index form.
Give your answer in terms of x.
ANSWER
[tex]5N^2=3^{2} \times 5^{5} \times x^{6}[/tex]
EXPLANATION
[tex]N=3\times5^2 \times x^3[/tex].
[tex]5N^2=5(3\times5^2 \times x^3)^2[/tex]
Recall this property of exponents;
[tex](a^m)^2=a^{m} \times a^m[/tex]
So our product becomes;
[tex]5N^2=5(3\times5^2 \times x^3) \times (3\times5^2 \times x^3)[/tex]
[tex]5N^2=5\times 3\times 3 \times 5^2 \times 5^2 \times x^3 \times x^3[/tex]
[tex]5N^2=3\times 3\times 5 \times 5^2 \times 5^2 \times x^3 \times x^3[/tex]
Recall this law of exponents:
[tex]a^m \times a^n =a ^{m+n}[/tex]
[tex]5N^2=3^{1+1} \times 5^{1+2+2} \times x^{3+3}[/tex]
[tex]5N^2=3^{2} \times 5^{5} \times x^{6}[/tex]
Radical expression for the exponential expression above
The answer is
[tex]\sqrt{x}[/tex]
because,
[tex]a^{x/n} = \sqrt[n]{x}[/tex]

(6.4+0.92 , 15.74 -2.64)
Alright, let's break this down:
1. First, we will solve the addition problem on the left, which is 6.4 plus 0.92. When you add these two numbers together, you will get 7.32.
2. Secondly, we will solve the subtraction problem on the right, which is 15.74 minus 2.64. When you subtract these two numbers, you will find that the result is 13.1.
So the answer to our problem is (7.32, 13.1).
−3r+10=15r−8 solve for R
Answer,
R = 1
Explanation,
Subtract 10 from both sides,
-3r + 10 - 10 = 15r - 8 - 10
Simplify,
-3r = 15r - 18
Subtract 15r from both sides,
-3r - 10 = 15r - 18 - 15r
Simplify,
-18r = -18
Divide both sides by -18,
-18r/-18 = -18/-18
Simplify,
R = 1
Hope this helps :-)
To solve the equation −3r+10=15r−8 for r, we first move all r terms to one side and constant terms to the other to get -18r = -18. We then divide both sides by -18 to find that r = 1.
Explanation:The question is asking us to solve the equation −3r+10=15r−8 for the variable r. To do this, we first combine all terms involving r on one side of the equation and constant terms on the other side. Therefore, the equation becomes:
−3r - 15r = -8 - 10
which simplifies to:
-18r = -18.
We then divide both sides of the equation by -18 to solve for r:
r = 1.

Gabby drove 124 miles in 150 minutes. Find Gabby's speed in kilometers per hour. (HELP FOR TEST TMRRW PLZ 15 POINTS!!!)
First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words the kilometers per hour, which equals 49.6 km/h
NEED HELP!!!!!!!!
George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30-x) feet. The diagram below shows his plan.
Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.
How many feet of fencing will George need for the dog run?
22 feet
68 feet
76 feet
82 feet
Answer:
68 feet
Step-by-step explanation:
30 x (30-x) = 240
30-x = 8
-x = -22
x = 22
Therefore width is 30-22 = 8 feet
8+8+30+30 = 76 total for all 4 sides.
George would need 76 feet of fencing for the dog run IF he was not using his house as one side of the run. Therefore, taking the 76 total feet that would be required to go around all 4 sides and subtracting the feet of one width (8 feet), gives a total of 68 feet.

Which expression represents "five less than three times x"?
A: 3x-5
B: 3-5x
C: 5x-3
D: 5-3x
A
three times x = 3 × x = 3x
less 5 means subtract 5 from 3x, hence
3x - 5 → A
Answer:
[tex]3x-5[/tex]
Step-by-step explanation:
"five less than three times x"
The unknown number is x
Three times x means we multiply 3 with x
So the expression becomes 3x
5 less than 3x means we subtract 5 from 3x
To get the expression we use variables and operators like +,- . x or divide
So the final expression becomes
[tex]3x-5[/tex]

the sum of 3 numbers is 13. the second number is 3 subtracted from 3 times the first. the third number is 4 times the first. what is the number
x + y + z = 13
y = 3x - 3
z = 4x
Because we have values for y and z, we can plug them into the original equation to find the value of x.
x + 3x - 3 + 4x = 13
Combine like terms.
8x - 3 = 13
Add 3 to both sides.
8x = 16
Divide both sides by 8.
x = 2
The value of x is 2.
Because we have the exact value of x, we can insert this into each x value to find the values of y and z.
y = 3(2) - 3
y = 3
z = 4(2)
z = 8
2 + 3 + 8 = 13

Darryl has $7 left in his pocket. He spent $9 on a book, $12 on a compact disc, and $4 on a magazine. How much money did he have at the beginning of the day?
He has 7 dollars left so...
We can add 7+9+12+4 to get the amount in the beginning
32$ to start with
Final answer:
To determine how much money Darryl had at the beginning of the day, we add the amounts he spent on a book, compact disc, and magazine to the money he has left, which totals $32.
Explanation:
The question involves solving a simple arithmetic problem regarding the total amount of money Darryl had at the beginning of the day, based on his expenditures throughout the day. To find out how much money Darryl had initially, we need to add up the amounts he spent on various items and then add the money he has left.
Darryl spent:
$9 on a book$12 on a compact disc$4 on a magazineand he has $7 left.
To find the total amount Darryl had at the beginning of the day, we add up all the expenditures and the remaining amount:
$9 (book) + $12 (compact disc) + $4 (magazine) + $7 (remaining) = $32
So, Darryl had $32 at the beginning of the day.

If an object is said to be moving at 10 m/s due north. The measurement 10 m/s north would be best described as
A) a speed.
B) a velocity.
C) neither a speed or velocity.
D) either a speed or a velocity.
Remark
Velocity is speed that has a direction. So the answer excludes both being true. C and D are both incorrect for the same reason: you cannot have both together when a direction is given.
Speed has no direction.
Answer: B Velocity has direction and a magnitude of speed.
"Sketch a possible graph for a negative Quintic polynomial with one real zero." Can anyone explain how this is done? And if possible provide a graph?
quintic means degree of 5.
a negative quintic would be: f(x) = -x⁵ +
an example with one real zero could be: -x⁵ + x³ + x + 3 (see attachment)
Well let's start with y = -x^5 and y = - x^5 +1
The graph looks like the one on the right for these two. The red one is y = - x^5 and the blue one is y = - x^5 + 1
See below on the right
You can tell that these two are correct because there is only 1 x axis intercept for each of them. That means there is only 1 real solution which is what you are calling for.
Another one could be something like
y = -(x - 5)(x^2 + 2)(x^2 + 3)
The graph of that is on the left.
