check the picture below.


27)

since those angles on the other side, are alternate interior angles, then ∡RST = 110°.

28)

for the same reason, those angles on the outside are alternate interior angles to 110° and 120°, and those angles outside are linear angles with the ones inside, recall linear angles add up to 180°.

therefore ∡RST = 130°.

Naya [18.7K]
For this case we have the following function:
 h (x) = - 5x ^ 2 + 10x + 15

 By the time the stone is thrown, x = 0.
 We must evaluate this value of x in the function.
 We have then:
 h (0) = - 5 (0) ^ 2 + 10 (0) +15

h (0) = 0 + 0 + 15

h (0) = 15 meters
 Answer:
 The height of the stone at the time is thrown is given by:
 h (0) = 15 meters

Multiply: (5x − 2)(4x2 − 3x − 2)
Alex Ar [27]
Hello there!

(5x - 2)(4x² - 3x - 2)

Use the distributive property

=(5x)(4x²) + (5x)(-3x) + (5x)(-2) + (-2)(4x²) + (-2)(-3x)² + (-2)(-2)

= 20x³ - 15x² - 10x - 8x² + 6x + 4

= 20x³ - 23x² -4x + 4


As always, it is my pleasure to help students like you. Let me know if you have any questions.

Turn 0.272727... into a fraction
kherson [118]

Answer:

0.272727… = 27/99

Step-by-step explanation:

(since 27 is the repeating part of the decimal and it contains 2 digits). We can reduce this fraction (a process that we'll talk more about in a future article) by noticing that we can divide both the numerator and denominator by 9 to get 0.272727… = 27/99 = 3/11.

Area is 96 length is 4x+8 width is x find x
dimulka [17.4K]

Answer

Step-by-step explanation:

The area would be length times width. x(4x+8) =96

4x^2+8x = 96

4x^2+8x-96=0. We need to factor.

It would be factored to (4x-16)(x+6) = 0

x would be -6 (x+6=0)

or x would be 4 (4x-16=0)

Why would the width be negative?!? So the answer is 4
