The answers are 3. right, and 5. isosceles. It is a right triangle because any triangle with a 90 degree angle is a right triangle, and it is isosceles because its two other angles, 45 and 45 degrees, are equal, meaning that their legs are the equal length as well.

Sarah had invested $800 in a savings account that paid 4.2% interest compounded annually. How much money was in the account afte
schepotkina [342]

Answer:  $943.11

<u>Step-by-step explanation:</u>

Compound Interest formula is:   A=P(1+r)^t     where

  • A is the Accrued amount (total earned)
  • P is the Principal (amount initially invested)
  • r is the interest Rate (convert percent to a decimal)
  • t is the Time (number of years)

It is given that; P = 800    r = 4.2% (0.042)       t = 4

A = 800(1 + 0.042)⁴

A = 800(1.042)⁴

A = 943.106   →   A = 943.11 (rounded to the nearest penny)

Sarah invested $800 for four years at an interest rate of 4.2% and accrued $943.11

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple pa
ValentinkaMS [17]

The two highlighted rows show that for the same amount of blue, Purple #1 uses <u>more</u> red than Purple #2.

This means that Purple #1 is <u>a redder</u> shade of purple than Purple #2.

Purple #2 is <u>a bluer</u> shade of purple than Purple #1.

Step-by-step explanation:

The two highlighted rows show that for the same amount of blue, Purple #1 uses <u>more</u> red than Purple #2.

Making blue's quantity as 3 parts for purple #1 implies red part becomes 1.5 to maintain the ratio 1:2

Purple #1 has 1/3 parts red and 2/3 parts blue. Purple #2 has 1/4th part red and 3/4th part blue.

Hence, Purple #1 is <u>a redder</u> shade of purple than Purple #2.

From the above explanation, <u>Purple #2</u> is a bluer shade of purple than Purple #1.

<em>Sure hopes this helps you :)</em>

Phoenix [80]

Answer:

The answer is B) 1/25

Step-by-step explanation:

This is because given that f(x) = 5^x

Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25

Because a^-b can be written as 1/a^b
