Step-by-step explanation:
If two zeroes of the polynomial f(x)=x3−4x2−3x+12 are √3 and -√3 then find its third zero.
Answer:
Third zero is 4
Step-by-step explanation:
The polynomial is;
f(x) = x³ − 4x² − 3x + 12
We are given 2 zeros which are √3 and -√3.
This means that a factor of the polynomial will b; (x² - 3) because when it is equated to zero, x will be √3 and -√3.
Now, to get the other factor of the polynomial, we have to divide x³ − 4x² − 3x + 12 by (x² - 3) using long division method.
I have attached this long division method and we have the third factor as; (x - 4)
Equating to zero, we have x = 4 as the third zero of the polynomial

If a circle has a circumference of 43.96 units, what is the approximate area of the circle? (Use 3.14 as an
approximation of pi.)
Answer:
If we were to use 3.14 as pi . . .
43.96/3.14 = 14
14/2 = 7
7 x 7 = 49
49 x 3.14 = 153.86
153.86 would be the correct answer
But if we were to use pi. . .
615.1279985 would be the answer.
Answer:154 rounded to whole number
Step-by-step explanation:
C=pi ×d
43.96 = 3.14 ×d
d= 43.96÷3.14
d= 14
So radius is 7 (half of diameter)
Area=3.14×7×7
=153.86

Answer:
-2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
In a set of three lines, a pair of parallel lines is intersected by a transversal. The intersection forms eight special angles.
Two of the special angles, A and B, are corresponding angles.
For the set of parallel lines intersected by a transversal, A = 4x and B = 2(x+14).
1. Use an equation to represent the corresponding angle relationship between A and B.
2. Use the equation to find the measures of A and B.
PLEASE HELP!!! Will mark brainliest and give thanks:)
Answer:
a.) 4x = 2(x + 14)
b.) Measure of A = 56°
Measure of B = 56°
Step-by-step explanation:
We know that,
When two lines are crossed by another line transversal line , the angles in matching corners are called corresponding angles.
Also,
When two lines are parallel then the Corresponding Angles are equal.
Given that,
A = 4x and B = 2(x+14).
i.e.
∠A = 4x and ∠B = 2(x+14)
a.)
Now,
As A and B are parallel
So,
∠A = ∠B
⇒4x = 2(x + 14)
(This is the equation that represent the corresponding angle relationship between A and B.)
b.)
Now,
⇒4x = 2x + 2(14)
⇒4x = 2x + 28
⇒4x - 2x = 28
⇒2x = 28
⇒x = 14
So,
we get
∠A = 4(14)
= 56
⇒∠A = 56°
and
∠B = 2(14 + 14)
= 2(28)
= 56°
⇒∠B = 56°
∴ we get
Measure of A = 56°
Measure of B = 56°

Answer:
8.236%
Step-by-step explanation:
P(G,G,G) = 8/17 x 7/16 x 6/15
= 7/85 (simplified)
7/85, in decimal form, is .082352
.082352 in percent form is 8.236%
help please ! I don’t remember the formula on how to get the answer.
Step-by-step explanation:
b = 4`² = 1/16 = 0.0625
c = 4`⁴ = 1/256 = 0.00390625
d = (⅔)° = 1
e = (⅔)² = 4/9 = 0.4444...
f = (⅔)⁴ = 16/81 = 0.197530864

i need help with geometry
Answer:
Choice A, x=1
Step-by-step explanation:
So, to start, there's two routes that you can take there. I am going to show one of these routes.
Within the image, you see two triangles, you are able to tell that these triangles share two of the same sides, because of congruency lines on each of them.
The first group of congruent sides have 1 line going through them, the second group has 2 lines going through them. Let's go with the first group.
With the first group, we are using the lines CB and FE, where the measurements on each of them are 3x+1 and x+3 respectively.
Since they are congruent, they are equal and we can just set them equal to each other.
Starting With:
3x+1 = x+3
Step 1) Cancel out the +1
3x+1 -1 = x+3 -1
3x = x+2
Step 2) Cancel out the x
3x -x = x+2 -x
2x = 2
Step 3) Divide by 2 get x by itself
2x/2 = 2/2
x=1

a right triangle has the legs length 3x meters and 4x meters and a hypotenuse of length 75 meters. find the lengths of the legs of the triangle
Step-by-step explanation:
I have included a drawing of the triangle.
we can use Pythagoreans theorem.
a^2+b^2=c^2
So,
(4x)^2+(3x)^2=75^2
16x^2+9x^2= 5,625
we can add like terms.
25x^2 = 5,625
25 25
x^2 = 225
Square root both sides.
x = 15
so, leg of 4x is
4(15)= 60 m
leg of 3x
3(15)= 45 m

A patio is made of two sections. One is shaped like a trapezoid, and the other like a semicircle. The bases of the trapezoid are 12 feet and 8 feet. The height of the trapezoid is 4 feet. The diameter of the semicircle is the same as the trapezoid's shorter base. Find the patio's area. Use 3.14 for pi.
Answer:
65.12 ft^2
Step-by-step explanation:
Patio's area = area of trapezoid + area of semicircle
Area of a trapezoid = 1/2 x (sum of the lengths of the parallel sides) x height
1/2 x ( 12 + 8) x 4 = 40 ft^2
Area of semicircle = (1/2)πr²
r = 8/2 = 4ft
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
(1/2) x 3.14 x 4^2 = 25.12 ft^2
Area of patio = 40 ft^2 + 25.12 ft^2 = 65.12 ft^2
t = 40
25.12

Tickets to a football game cost 5$ for students and 7$ for adults. write and solve a system of equations to determine the number to student tickets sold and the number of adult tickets sold at the most recent home football game if a total of 680 people purchased tickets and the ticket booth sold 3,914 worth of tickets. Does anyone know the equation? Tysm in advance tho if you help!
Answer:
x + y = 680
5x + 7y = 3914
Step-by-step explanation:
Let the amount of students who purchased tickets equal x.
Let the amount of adults who purchased tickets equal y.
If you add the amount of adults and students, you get the total amount of people:
x + y = 680
Also, to find the amount students spent on tickets, you multiply the ticket price by the amount of students to get 5x. And to find the amount adults spent on tickets, you multiply the ticket price by the amount of adults to get 7y. By adding the two amount, you get the total amount of money:
5x + 7y = 3914
These are the two equations:
x + y = 680
5x + 7y = 3914
