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 :)

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]

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.

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.

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

Answer:

m=-17/4

Step-by-step explanation:

Slope is equal to m= y-y/x-x

Therefore it will be 9-(-8)/-4-0

Answer:

[tex]\boxed {\boxed {\sf m= - \frac{17}{{4}}}}[/tex]

Step-by-step explanation:

We are asked to find the slope of (0, -8) and (-4, 9). We use the following formula to calculate slope.

[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We have the points (0, -8) and (-4,9). If we match the given value with the corresponding variable we see that:

Substitute the values into the formula.

[tex]m= \frac{(9)- (-8)}{ (-4) -(0)}[/tex]

Solve the numerator. Remember that 2 back to back negative signs become a positive sign.

[tex]m= \frac{17}{(-4)-(0)}}[/tex]

Solve the denominator.

[tex]m= \frac{17}{-4}[/tex]

This fraction cannot be reduced, so -17/4 is the slope.

Answer: 1

Step-by-step explanation:

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.

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.
