Jillian plans a pillow pattern before sewing. The parallelogram in the center of the pattern has a base length of 9 inches and a height of 7 inches. She needs to find the area of the fabric surrounding the parallelogram pattern. Which statements below should she apply when solving this problem? Check all that apply. A parallelogram is inside of a rectangle with height 8 inches and base 16 inches The parallelogram has a base length of 16 inches and a height of 8 inches. The area of the parallelogram is (9) (7) = 63. The total area of the block is 128 square inches. The area surrounding the parallelograms can be found by adding 63 to 128. The area surrounding the parallelogram can be found by subtracting 63 from 128. Mark this and return

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

they used 313 gallons of paint

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

y=sec x is the correct answer
