Answer:

Step-by-step explanation:

90+42 angle S=180 degree(being sum of interior angles of a triangle)

132 angle S=180

angle S=180-132

angle S=48 degree

Mr. Webb gave his waiter a $8.60 tip on a $50 bill. What percent did he give the waiter?

Dominik [7]

<u>8.60</u> = <u> X </u>
50 100

"Percent" means "out of one hundred" (Latin).
Multiply the top by two, since 100 is twice 50, and the fractions will be equal.
The answer is 17.2%.

Please graph! 90 points! And BRAINLIEST

daser333 [38]

The points on the graph are:

Midline point = (0,-5)
Maximum point = (0.65,-2)

<h3>(a) The graph of the function</h3>

The equation of the function is given as:

$f(x) = 3\sin(12x) - 5$

See attachment for the graph of the function f(x)

<h3>(b) The midline point</h3>

This is the point that is on the line that passes through the midsegment of the function.

From the graph, a point on the midline is (0,-5)

<h3>(c) The maximum point</h3>

This is the point that is on the vertex of the function.

From the graph, a point on the midline is (5pi/24,-2)

This can be rewritten as: (0.65,-2)

Write a quadratic equation given the roots -1/3 and 5, show your work

Travka [436]

$\boxed{(x - a)(x - b) = 0}$

The equation above is the intercept form. Both a-term and b-term are the roots of equation.

$x = - \frac{1}{3} \\ x = 5$

These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.

$(x + \frac{1}{3} )(x - 5) = 0$

Here we can convert the expression x+1/3 to this.

$x + \frac{1}{3} = 0 \\ 3x + 1 = 0$

Rewrite the equation.

$(3x + 1)(x - 5) = 0$

Simplify by multiplying both expressions.

$3 {x}^{2} - 15x + x - 5 = 0 \\ 3 {x}^{2} - 14x - 5 = 0$

<u>Answer</u><u> </u><u>Check</u>

Substitute the given roots in the equation.

$3 {(5)}^{2} - 14(5) - 5 = 0 \\ 75 - 70 - 5 = 0 \\ 75 - 75 = 0 \\ 0 = 0$

$3( - \frac{1}{3} )^{2} - 14( - \frac{1}{3}) - 5 = 0 \\ 3( \frac{1}{9} ) + \frac{14}{3} - 5 = 0 \\ \frac{1}{3} + \frac{14}{3} - \frac{15}{3} = 0 \\ \frac{15}{3} - \frac{15}{3} = 0 \\ 0 = 0$

The equation is true for both roots.

<u>Answer</u>

$\large \boxed {3 {x}^{2} - 14x - 5 = 0}$
