At a certain store, the taco sauce was on sale for 1/5 off. With a coupon for an additional 40 cents off, the final cost of the

sauce was $1.20.
Which equation will help Marvin to figure out how much his payment will be?
Let x = one installment

A) c - 1/5c + 40 = 120
B) c - 1/5c - 40 = 120
C) 1/5c = 120 - 40
D) 1/5c = 120 + 40

B) c - 1/5c - 40 = 120


c- (original cost) - 1/5c (sale) - 40(coupon)= 120(final cost)

Hope that helps! :)

<h2><u>Part 1: Define</u></h2><h3>Part 1i) Defining "adjacent angles"</h3>

In this case, adjacent angles are such pairs of angles that are alongside each other. Therefore, we can say that the sum of the two adjacent angles forms a bigger angle.

<h3>Part 1ii) Defining "vertical angles"</h3>

In this case, vertical angles are such angles that are on opposite sides of the intersection between two lines. It is understood that vertically opposite angles are equivalent.

<h2><u>Part 2: Solve</u></h2><h3>Problem 8:</h3>

Clearly, we can see that two angles (one angle known as ∠x and the other angle) are alongside each other. Therefore, we can tell the angles are adjacent angles.

As we can see a \square, we can tell that the sum of the measure of ∠x and the other angle is 90°. Therefore, we obtained;

  • ⇒ ∠x + 35 = 90
  • ⇒ ∠x = 90 - 35
  • ⇒ ∠x = 65°

Therefore, the measure of ∠x is 65°.

<h3 /><h3>Problem 9:</h3>

Clearly, we can see that two angles (one angle known as ∠x and the other angle) are on opposite sides. Therefore, we can tell that the angles are vertically opposite angles.

As stated in part 1ii, vertical angles are equivalent. Since ∠x and the other angles are vertically opposite angles, the measure of ∠x is 128°.

<h3 /><h3>Problem 10:</h3>

Clearly, we can see that two angles (one angle known as ∠x and the other angle) are alongside each other. Therefore, we can tell the angles are adjacent angles.

Since the line shown, is a straight line, we can tell that the sum of 117 and x is 180. Therefore, we obtain the following equation;

  • 117 + ∠x = 180°

<u>When isolating x, we get;</u>

  • ⇒ 117 + ∠x - 117 = 180° - 117
  • ⇒ ∠x = 180° - 117
  • ⇒ ∠x = 63°

Therefore, the measure of ∠x is 63°

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 52t - 16t^2 . What i
ahrayia [7]

Answer:

42.25 feet

Step-by-step explanation:

The height function is a parabola.  The maximum value of a negative parabola is at the vertex, which can be found with:

x = -b/2a

where a and b are the coefficients in y = ax² + bx + c.

Here, we have y = -16t² + 52t.  So a = -16 and b = 52.  The vertex is at:

t = -52 / (2×-16)

t = 13/8

Evaluating the function:

h(13/8) = -16(13/8)² + 52(13/8)

h(13/8) = -169/4 + 169/2

h(13/8) = 169/4

h(13/8) = 42.25
