Let's begin by listing out the information given to us:

Angle U = 27°

TU is tangent to S implies this is a right triangle

Angle T = 90°

The sum of interior angles in a triangle is 180 degrees

U + T + S = 180°

⇒27 + 90 + S = 180

⇒S = 180 - (90 + 27) = 53

S = 53°

Explanations:

Let the numerator of the fraction be x and let the denominator be y.

so

the lower price is $22.56

50%=50/100=0.50

0.50(22.56)=$11.28step 2

step 2

adds the costs

11.28+24.77=$36.05

answer C

The equation that can be used to determine the length and width of the garden is x² + 2x - 24 =0, the length is 6 feet and the width is 4 feet.

There is a rectangular garden with an area of 24 square feet

The garden is 2 feet longer than it is wide

Let the width of the garden be x

Then, the length of the garden is x + 2

The area of a rectangular garden = length of the garden x width of the garden

24 = x (x + 2)

x² + 2x - 24 =0

x² + 6x - 4x - 24 = 0

x(x + 6) -4(x + 6) = 0

(x - 4)(x + 6) = 0

x - 4 = 0

x = 4

Width of the rectangular garden is 4 feet

Length of the rectangular garden is (4 + 2) feet = 6feet

Therefore, the equation that can be used to determine the length and width of the garden is x² + 2x - 24 =0, the length is 6 feet and the width is 4 feet.

Given equation is, (Dollar value of a sandwich shop of a tip jar)

h is the number of hours since the shop opened.

a) To find the value where the tip jar increasing per hour.

we know that,

A slope of a line is the change in y coordinate with respect to the change in x coordinate.

The slope or gradient of a line is a number that describes both the direction and the steepness of the line. That gives the value of the rate of y with respect to x.

The equation of a line with slope and intercept is,

y=mx+c

where m is the slope.

The increasing value of a tip jar per hour is the slope of the given equation.

The slope of the ginen equation is,

we get,

$0.65 is value of the tip jar increasing per hour

Answer is: $0.65 is value of the tip jar increasing per hour.

b) To find the initial value of the tip jar when the shop opens.

Given equation is, (Dollar value of a sandwich shop of a tip jar)

h is the number of hours since the shop opened.

When the shop opens, we get that h=0

Substitute h=0 in the given equation we get,

Therefore, the initial value of the tip jar when the shop opens is $1.25.

Answer is: Therefore, the initial value of the tip jar when the shop opens is $1.25.

Answer:

(D). f(x) = [tex]-\frac{3}{2}[/tex] x² + [tex]\frac{17}{2}[/tex] x - 7  

Step-by-step explanation:

( x , y )

ax² + bx + c = y ............ ( 1 )

~~~~~~~~~~~~~~

( 2 , 4 ) --------> ( 1 )

a(2)² + b(2) + c = 4

4a + 2b + c = 4 .............. (2)

( 3 , 5 ) ---------> ( 1 )

a(3)² + b(3) + c = 5

9a + 3b + c = 5 ............... (3)

( 4 , 3 ) ----------> ( 1 )

a(4)² + b(4) + c = 3

16a + 4b + c = 3 .............. (4)

[tex]delta[/tex] = Δ = [tex]\left[\begin{array}{ccc}4&2&1\\9&3&1\\16&4&1\end{array}\right][/tex] = - 2

[tex]delta_{a}[/tex] = [tex]\left[\begin{array}{ccc}4&2&1\\5&3&1\\3&4&1\end{array}\right][/tex] = 3

[tex]delta_{b}[/tex] = [tex]\left[\begin{array}{ccc}4&4&1\\9&5&1\\16&3&1\end{array}\right][/tex] = - 17

[tex]delta_{c}[/tex] = [tex]\left[\begin{array}{ccc}4&2&4\\9&3&5\\16&4&3\end{array}\right][/tex] = 14

a = [tex]delta_{a}[/tex] / [tex]delta[/tex] = [tex]-\frac{3}{2}[/tex]

b = [tex]delta_{b}[/tex] / [tex]delta[/tex] = [tex]\frac{-17}{-2}[/tex] = [tex]\frac{17}{2}[/tex]

c = [tex]delta_{c}[/tex] / [tex]delta[/tex] = [tex]\frac{14}{-2}[/tex] = - 7

f(x) = [tex]-\frac{3}{2}[/tex] x² + [tex]\frac{17}{2}[/tex] x - 7   (D)

Given:

Two intergers have a sum of 47 and a difference of 23.

Let's find the product of the two numbers.

Let x and y represent the numbers.

We have:

Two integers have a sum of 47: x + y = 47

Two integers have a difference of 23: x - y = 23

We gave the system of equations:

x + y = 47.......................equation 1

x - y = 23.......................equation 2

Let's solve the system simultaneously using substitution method.

Rewrite equation 1 for x:

x = 47 - y

Substitute (47 - y) for x in equation 2:

(47 - y) - y = 23

47 - y - y = 23

47 - 2y = 23

Subtract 47 from both sides:

47 - 47 - 2y = 23 - 47

-2y = -24

Divide both sides of the equation by -2:

Now, substitute 12 for y in either of the equations.

Let's take equation 1.

x + y = 47

x + 12 = 47

Subtract 12 from both sides:

x + 12 - 12 = 47 - 12

x = 35

Therefore, we have:

x = 35, y = 12

The numbers are 35 and 12.

To find the product of the numbers, let's multiply the numbers:

35 x 12 = 420

Therefore, the product of the numbers is 420.

ANSWER:

420

The distance travelled by the ball is 0.9076 feet.

Foucault used a pendulum to demonstrate the earth’s rotation. There are now over 30 Foucault pendulum displays in the United States. The Foucault pendulum at the Smithsonian Institution in Washington, DC, consists of a large brass ball suspended by a thin 52-foot cable. The ball swings at an angle of 1°. We have to find the distance travelled by the ball.

The ball travels in a circular motion. The radius of the circle is equal to the length of the cable. The distance travelled by the ball is equal to the arc length traversed in circular motion. Let the radius, angle, and distance be denoted by the variables "r", "θ", and "d", respectively.

r = 52 feet

We need to convert the angle from degrees into radians.

θ = 1°

θ = 1°*(π/180°)

θ = π/180

The formula for arc length is used below to calculate the distance.

d = r*θ

d = 52*(π/180)

d = 0.9076

You can observe that angle 1 and angle with 47° are inside a parallelogram.

Consider that the sum of the internal angles of a parallelogram is 360°.

Moreover, consider that the angle at the top right of the parallogram is congruent with the angle of 47°, then, such an angle is if 47°.

Consider that angle down right side is congruent with angle 1, then, they have the same measure.

You can write the previous situation in the following equation:

47 + 47 + ∠1 + ∠1 = 360 simplify like terms

94 + 2∠1 = 360 subtract both sides by 94

2∠1 = 360 - 94

2∠1 = 266 divide by 2 both sides

∠1 = 266/2

∠1 = 133

Hence, the measure of angle 1 is m∠1 = 133°

The value of x for the given triangle is 65°.

According to the question,

We have the following information:

A figure of triangle is given where two of its angles are 68° and 47°.

We know that the sum of all three angles of a triangle is 180°.

(More to know: all angles in an equilateral triangle are equal and in an isosceles triangle two angles are equal however the sum of three angles is 180°.)

So, we have the following expression:

x+68+47 = 180

x+115 = 180

x = 180-115

x = 65°

Hence, the value of x for the given triangle is 65°.
