I need to know how to get the scale factor from a h-shaped polygon

1 answer:

5 0

“To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.”

Please help!! I tried rise / run

garik1379 [7]

Answer:

d=6.08

Step-by-step explanation:

The points given on the graph are (3,1) and (4,-5). Using this information, we can plug the points into the distance equation.

The first point = $(x_{1} , y_{1} )$

The second point = $(x_{2}, y_{2})$

$d=\sqrt{(x_{2}-x_{1})^2 +(y_{2} -y_{1})^2 }$

$d=\sqrt{(4-3)^2+((-5)-1)^2\\} \\d=\sqrt{(1)^2+(-6)^2}\\d=\sqrt{1+36} \\d=\sqrt{37} \\d=6.08$

According to the Rational Root Theorem, the following are potential roots of f(x) = 60x2 – 57x – 18. Which is an actual root of

emmainna [20.7K]

Answer: The correct option is third, i.e., $-\frac{1}{4}$ .

Explanation:

The given function is,

$f(x)=60x^2-57x-18$

The Rational Root Theorem states that the rational roots are in the form of,

$r=\frac{\text{factors of constant term}}{\text{factor of leading coefficient}}$

These rational roots are possible rational roots not the actual roots of f(x).

For actual roots of f(x), the value of the function is 0.

Put each value of x from the option in the function, if we get the value of f(x) is 0, then that value is the actual root of f(x).

Put x=3.

$f(3)=60(3)^2-57(3)-18=351\neq 0$

Put x=6

$f(6)=60(6)^2-57(6)-18=1800\neq 0$

Put $x=-\frac{1}{4}$

$f(-\frac{1}{4})=60(-\frac{1}{4})^2-57(-\frac{1}{4})-18=0$

Put $x=-\frac{6}{5}$

$f(-\frac{6}{5})=60(-\frac{6}{5})^2-57(-\frac{6}{5})-18=136.8\neq 0$

Only for $x=-\frac{1}{4}$ the value of function is 0, therefore the correct option is third.

Okay. So the formula for the amount of time is I / Pr, meaning you multiply the principal and the rate in decimal form together, and you divide the amount of interest by that number. The formula for finding the interest rate is I / Pt, meaning you multiply the principal and time, and the you divide the amount of interest by that number. With a decimal, be sure to multiply by 100 to get the whole percentage. With that being said, if you solve this correctly, here are your answers.

Principal: $6,631
Interest Rate: 8.05%
Time: 33 months
Simple Interest: $1,467.94

Principal: $884,706
Interest Rate: 5.42%
Time: 40 months
Simple Interest: $159,931

Note: For times in months, you'll have to do some conversion into decimals, but you know that 12 months equal 1 year, so you can divide the time period by 12. For the second part, I happened to get 5.43% when I worked it out, but a calculator happened to round off to 5.42%, so it's a bit confusing, but those are the answers.

TUVW is a rhombus. Solve for x

Tpy6a [65]

Answer:

x=17inches

Step-by-step explanation:

we know a rhombus has equal sides so we need to make the equation equal.

2x+16=33+x.

move x to one side and numbers (16) to the opposite side

2x-x=33-16

add them up.

x=17
