What is the radius of a circle whose equation is (x + - 5)2 + (y - 3)2 = 42?
2 units
4 units
8 units
16 units
Answer:
Step-by-step explanation:
The equation of the form
[tex](x-a)^2+(y-b)^2 =r^2[/tex]
has radius r.
Now your equation is
[tex](x-5)^2+(y-3)^2=42[/tex]
Hence its radius is [tex]\sqrt{42}[/tex]
The radius of the circle is root 42.
We have given that equation of the circle
[tex](x + 5)^2 + (y - 3)^2 = 42[/tex]
What is the general form of the circle?[tex](x-a)^2+(y-b)^2=r^2[/tex]here we have (a,b) as the center of the circle
r is the radius of the circle
[tex]r^2=42[/tex]
taking square root on both sides.
[tex]r=\sqrt{42}[/tex]
Therefore,The radius of the circle is root 42.

find the size of unknown angles
Explanation :
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
x = 22° × 2x = 44°y = 44° ( cuz, x = y )HELP DUE IN 10 MINUTES!!

Which equation is an identity?
A. (9x/15) + 27 = (9x/15) + (27/15)
B. 3((x/2) + 16) - 16 = (3/2)x
C. -4(3 - 2x) = -12 - 8x
D. -5((x/15) - 16) - 30 = 50 - (1/3)x
E. 36((3/4)x- 2) + 72 =-72 + 27x
Answer:
C.
Step-by-step explanation:
An equation is an identity if the equation is always true regardless of what value you replace 'x' with.
This means we need to simplify the equations above to see which one will be true for any value of 'x'.
After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

Actually what is the meaning of numbers of terms? Example :the [PICTURE] question 1 the ans is 84 what is the 84 means? Pls answer it clearly,thanks.
WILL MARK AS BRAINLY.
Consider the expression (x+5)^2
It expands out to x^2+10x+25 which has 3 terms.
The original expression has k = 2 terms inside the parenthesis and n = 2 is the exponent.
We then see that n+(k-1) = 2+(2-1) = 3 and k-1 = 2-1 = 1 is applied to this nCr combination formula to count the number of terms. You should find the result is 3.
If you kept k = 2 the same, and bumped things up to n = 3, then you should get 4 terms when you apply that modified nCr formula. That means something like (x+5)^3 will have 4 terms after simplifying everything and combining like terms.
For binomials of the form (A+B)^n, there are n+1 terms.
-------------------------
This idea can be extended for k values that are larger than 2.
For problem 1, if n = 6 and k = 4, then we have
n+(k-1) = 6+(4-1) = 9
k-1 = 4-1 = 3
Then plugging those values into the formula you're given leads to 84. There are 84 terms in the expansion of (1+2x-7y+d)^6. Honestly, having this many terms is really difficult to verify by hand. It's not as easy compared to something like (x+5)^3. However, you can use CAS (computer algebra software) to expand out (1+2x-7y+d)^6 and confirm that there are indeed 84 terms. This is after all like terms are combined.
Problems 2 and 3 follow the same idea, but with different n and k values.
Point F is on line segment EG. Given FG = 3x – 5, EF = x, and
EG = 5x – 8, determine the numerical length of FG.
A line segment can have one or more points on it. The numerical length of FG is 4
Given that:
[tex]FG = 3x - 5[/tex]
[tex]EF = x[/tex]
[tex]EG = 5x - 8[/tex]
Because point F is on EG, then:
[tex]EG = EF + FG[/tex]
So, we have:
[tex]5x - 8 = x + 3x - 5[/tex]
[tex]5x - 8 = 4x - 5[/tex]
Collect like terms
[tex]5x - 4x = 8 - 5[/tex]
[tex]x =3[/tex]
Recall that:
[tex]FG = 3x - 5[/tex]
Substitute [tex]x =3[/tex]
[tex]FG = 3 \times 3 - 5[/tex]
[tex]FG = 9 - 5[/tex]
[tex]FG = 4[/tex]
Hence, the numerical length of FG is 4

Multiply the polynomials: (x + 3)(x2 – 5x + 12)
Answer:
x³ - 2x² - 3x + 36
Step-by-step explanation:
(x + 3)(x² - 5x + 12)
Each term in the second factor is multiplied by each term in the first factor , that is
x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis
= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms
= x³ - 2x² - 3x + 36
how do you convert a repeating decimal in the 10000 place into a fraction?
Decimal to Fraction
Converting any terminating decimal into a fraction is fairly straightforward. You count the number of decimal places, move the decimal point that number of places to the right, and put the resulting number over "1" followed by that number of zeroes.
For instance:
Convert the decimal 0.7 into a fraction.
This decimal has one decimal place, so I move the decimal point one place to the right, to get 7. Then I put this over "1" followed by one zero (otherwise known as "10") to get: 7/10

Create a word problem using 30+2d as the answer
Answer:
Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with d being how many gigabytes she uses per month.
Step-by-step explanation:
We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be d therefore d is how many gigabytes she uses per month.

Simplify the ratio
40 : 28
Please show work! If your able too :)
Answer:
10:7
Step-by-step explanation:
ratios are simply just like fractions!
this ratio (40:28) can be re-written as 40/28
now, you can simplify this to its lowest terms
40/28=20/14=10/7
first in those steps i re wrote the question, then divided by two, then divided by two again !
so, 40:28=10:7
--------------------------------
you can even check this by cross multiplying, since ratios are fractions
[tex]\frac{40}{28} =\frac{10}{7}[/tex]
40x7=28x10
280=280
they are equivalent which means our ratio is correct :)

The two containers are mathematically similar in shape.
The larger container has a volume of 3456 cm3 and a surface area of 1024 cm2.
The smaller container has a volume of 1458 cm3.
Calculate the surface area of the smaller container.
Answer:
1458/3456 = 27/64 (simplification)
cube root of 27/64 = 3/4
square of 3/4 = 9/16
9/16 multplied by 1024 = 576.
