The diameter of a circle is 6 centimeters. What is the circle's area?
Use 3.14 for pi
Step-by-step explanation:
diameter=
[tex]2 \times\pi \times r = 6 \\ r = \frac{6}{2 \times 3.14} = 0.955 \\ area = \pi \times {r}^{2} = 3.14 \times {0.955}^{2} \\ = 2.87\: {cm}^{2} [/tex]
Matti has one more pencil than Chang-Lin. Renaldo had three times as many as Chang-Lin, and one more than Jorge. Jorge has 5 pencils, how many pencils does Matti Have?
Answer:Matti has 3pencils
Step-by-step explanation:
Given that Jorge has 5pencils
Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils
But also
Renaldo =3Chang-Lin
6==3Chang-Lin
Chang-Lin = 6/3 =2
Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils

10. Expand and Simplify (r+3) (r+11)=
Answer:
r^2 + 14r + 33
Step-by-step explanation:
Apply the "FOIL" method for multiplying two binomials:
(r+3) (r+11) = r^2 (first terms) +
+ 33 (last terms) +
+ 11r (outer terms) +
+ 3r (inner terms)
Combining ilke terms, we get:
r^2 + 14r + 33
Find the value of csc theta, I'd cos thetA =-1/4;180< theta<270
I know it's a little late, but hopefully it helps :)
I will greatly appreciate if you can solve this question!
Answer: The answer would be B
Write out the equation in slope-intercept form:
y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)
Subtract -5/3 from both sides of the equation:
y+5/3x=6
Subtract 6 from both sides:
y+5/3x-6=0
Multiply both sides by 3 to get rid of the fraction:
3y+5x-18=0
Then arrange the numbers to x and y are on one side by itself:
3y+5x=18
And that's your answer!
Hope this helped you!

A) 7.0
B) 6.1
C) 7.5
D) 6.8
Answer:
A) 7.0
Step-by-step explanation:
By angle bisector property:
[tex] \frac{x}{7.9} = \frac{18}{20.4} \\ \\ x = \frac{18 \times 7.9}{20.4} \\ \\ x = \frac{142.2}{20.4} \\ \\ x = 6.97058824 \\ \\ x \approx \: 7.0[/tex]

19.87 but there’s a 20% discount what’s the answer now?
19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.

Write the ratio in its simplest form:
Convert
2m : 8cm: 40mm
Answer:
2000mm:80mm:40mm
because 1 m is 1000mm and 1 cm is 10 mm so 2m will be 2000 mm and 8cm will be 80 mm
The simplified ratio will be equal to 10 : 40: 2.
What is a ratio?In mathematics, a ratio is a comparison between two quantities or numbers. It is expressed as the quotient or fraction of one number divided by another.
To simplify the ratio of 2m: 8cm: 40mm, we need to convert all the measurements to the same units. One meter is equal to 100 centimeters, so we can convert meters to centimeters by multiplying by 100. One centimeter is equal to 10 millimeters, so we can convert centimeters to millimeters by multiplying by 10.
2m: 8cm: 40mm
= 200cm : 8cm : 40mm (2m = 200cm)
= 200cm : 800mm : 40mm (8cm = 80mm)
= 10 : 40 : 2 (divide all terms by 40 to simplify)
Therefore, the simplified ratio is 10 : 40: 2.

I got three questions that need to be answered.
For questions 1-3, solve for x. Round your answer to the nearest tenth.
Answer:
1.)x=15.9
2.)x=17.49
3.) x=7.29
Step-by-step explanation:
For all the questions use Pythagorean Theorem which is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]
C=opposite of hypotenuse
A=Leg
B=Leg
1.) [tex]6^{2}[/tex]+[tex]b^{2}[/tex]=[tex]17^{2}[/tex]
Simplify the equation
36+[tex]b^{2}[/tex]= 289
Subtract 36 from both sides
[tex]b^{2}[/tex]=289
Square Root both sides to equal 15.9
Do the same for questions 2-3

Answer:
(x -2)² +(y -4)² = 25
Step-by-step explanation:
The area of a square is half the product of the diagonals, so that product is 50·2 = 100. This is the square of the diameter, so the square of the radius is 100/4 = 25. Then the circle equation is ...
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r

Write a polynomial function of least degree with rational coefficients so that P(x)0 has the given roots. x=-5, x=10
Answer:
P(x) = x² - 15x + 50
Step-by-step explanation:
We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.
Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0
Expanding the brackets, we have
x² - 10x - 5x + 50 = 0
Simplifying, we have
x² - 15x + 50 = 0 = P(x)
Thus,
P(x) = x² - 15x + 50
