Given the function f(x) = - 5x² – 13x – 5,
f(20) = ???
Answer:
-2265
Step-by-step explanation:
First, we replace x with 20.
[tex]f(20)=-5*20^2-13*20-5[/tex]
Then, we evaluate.
The * stands for multiplication.
[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]
[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]
[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]
[tex]f(20) = - 2000 - 260 - 5[/tex]
[tex]f(20) = - 2265[/tex]

I need help with biconditinal statements in geometry
[tex]\huge\underline\mathcal\pink{₳₦₴₩ɆⱤ:-}[/tex]
Biconditional statements do not use the key words 'if' and 'then.' Biconditional statements are true statements that combine the hypothesis and the conclusion with the key words 'if and only if.'
For example, the statement will take this form: (hypothesis) if and only if (conclusion). We could also write it this way: (conclusion) if and only if (hypothesis). If you figured out that both the conditional and converse statements have to be true for a biconditional statement to exist in geometry, you are correct. It's like a reversible jacket; you can wear it on both sides.
Let's rewrite our last example:
Conditional statement: If a polygon has three sides, then it is a triangle.
Converse statement: If a polygon is a triangle, then it has three sides.
Since both are statements are true, we can go ahead and make our biconditional statements:
A polygon is a triangle 'if and only if' it has three sides.
A polygon has three sides 'if and only if' it is a triangle.
Since we can write two biconditional statements, we could also define them as compound statements, since both the conditional and the converse statements have to be true. Let's practice some more.
Follow me❤Oliver's Flavored Popcorn comes in cylindrical tins divided into three equal sections of caramel, cheese, and buttered flavors. If the tin is 10 inches in diameter and 15 inches tall, what is the volume to the nearest tenth of only the cheese popcorn?
Answer:
The volume of only the cheese popcorn is 392.5 cubic inches.
Step-by-step explanation:
To determine the volume of only the cheese popcorn,
First, we will determine the volume of the cylindrical tin
The volume of a cylinder is given by
V = πr²h
Where V is the volume of the cylinder
π is a constant, (Take π = 3.14)
r is the radius of the cylinder
and h is the height of the cylinder
From the question, the tin is 10 inches in diameter and 15 inches tall.
Diameter = 10 inches, therefore, we can find radius
Radius = Diameter/2 = 10/2 = 5 inches
r = 5 inches
h = 15 inches
Now, putting the values into the equation, we get
V = 3.14 × 5² × 15
V = 1177.5 cubic inches
This is the volume of the cylindrical tin.
Since the cylindrical tin is divided into three equal sections of caramel, cheese, and buttered flavors, then the volume of only the cheese popcorn will be one-third of the total volume of the cylindrical tin.
∴ The volume of only the cheese popcorn = 1/3 × 1177.5 = 392.5 cubic inches
Hence, the volume of only the cheese popcorn is 392.5 cubic inches.

Hannah wants to buy a $540 camera. She can save $40 each week from her paycheck. However, before Hannah can buy the camera, she must give her brother $60 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera?
Answer:
w = 12
Step-by-step explanation:
Create formula:
540 = 40w - 60 where 540 is the cost of the camera, 40 is the amount saved, w is the number of weeks, 60 is the amount owed
Solve for w
540 = 40w - 60: subtract 60
480 = 40w: divide by 40
w = 12
Label the following numbers as rational or irrational
Answers:
a) rationalb) rationalc) rationald) irrationale) rationalEverything is rational but choice D
=======================================================
Explanation:
A rational number is anything in the form p/q where p and q are integers. The value of q cannot be zero.
So that's why -4/11 is rational. Here we have p = -4 and q = 11.
Any terminating decimal is rational. For choice A, we have 3.14 = 314/100
Choice C is also rational because [tex]\sqrt{\frac{4}{9}} = \frac{\sqrt{4}}{\sqrt{9}} = \frac{2}{3}[/tex]
Choice E is rational since 6 = 6/1.
In short, choices A, B, C, and E are rational.
------------------
The only irrational answer is d) 2pi
pi is irrational because we cannot write it as a fraction of two integers. Any number in the form n*pi, where n is any integer, is also irrational.

Answer: SOLVE FOR X !
Step-by-step explanation:
please explain this someone
Answer:
A. x=5
B. Look at image for answer
Step-by-step explanation:
No she is not correct.
Since both angles have the same measurement you set them equal to each other as so & solve for x
2x+90= x+95
x+90=95
x=5
In order to find the angle measurements you plug in 5
2(5)+90
10+90
= 100 degrees
Supplementary angles add up to 180 degrees so the angle next to the 100 degree one is 80 degrees
Help!! Willmark brainliest!Can you guys please answer these 2 questions???
Answer:

2. F, 15
If there are exactly 2.54 centimeters in 1 inch, how many inches are in 1 centimeter
Round to two decimal places.
===============================
Work Shown:
2.54 cm = 1 inch
2.54/2.54 cm = 1/2.54 inch ...... divide both sides by 2.54
1 cm = 0.39370078740158 inches
1 cm = 0.39 inches

The sets of numbers 3, 4, 5, and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!
Answer:
Pythagorean Theorom: a^2+b^2=c^2
Take the largest number of each as C (hypotenuse)
3,4,5
(3)^2+(4)^2= (5)^2
25=25
Therefore it is a Pythagorean Triple.
8,15,17
(8)^2+(15)^2=(17)^2
289=289
Therefore it is a Pythagorean Triple.
10) if the pattern indicated below is continued, what would be the total number of cubes in the 5th stage
of the pattern?
a) 55
b) 36
c) 45
d) 30
Answer:
Option A. 55
Step-by-step explanation:
From the diagram given above, we discovered that the number of cubes in each stage is simply the addition of the squares of the number from 1 to the stage number i.e
1st Stage = 1² = 1 cube
2nd Stage = 1² + 2² = 1 + 4 = 5 cubes.
3rd Stage = 1² + 2² + 3² = 1 + 4 + 9
3rd stage = 14 cubes
With the above idea in mind, we can obtain the number of cubes in the 5th stage as illustrated below:
5th stage = 1² + 2² + 3² + 4² + 5²
5th stage = 1 + 4 + 9 + 16 + 25
5th stage = 55 cubes
Thus, there are 55 cubes in the 5th stage.

d) n + (n − 1) + (n − 3) = 36
quick and simpler please im practicing this for class
Answer:
a=9/100 b= 7/20
Step-by-step explanation:
For a all you do is take the 9 out of the 100 in 1.
For b, all you do is take the 35/100, and then simplify it, so in this case it is 7/10 if you divide both the numerator and denominator by 5.
So a = 9/100 and b = 7/20
