Answer:

$11.60

Step-by-step explanation:

$9.39

Tax: 3.5%

3.5 ÷ 100 = 0.035 × 9.39 = 0.33

Tax 0.33

9.39 + 0.33 = $9.72

Tip: 20%

20÷ 100 = 0.2 × 9.39 =1.88

tip 1.88

9.72 + 1.88 = 11.60

total $ 11.60

$11.60

In parallelogram STUV, find the measure of TS.

Answers

Answer:

123.8 cm

Step-by-step explanation:

well we know that STUV is a parallelogram (given)

so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)

so we have that

VU=TS

and we know that VU=123.8 cm (given)

so TS=123.8

1) Find the inverse of the function below. Use g-1(x) to indicate the inverse 5 points
function. Use SQRT to indicate square root and use parenthesis for
fractions. Example: 9-1(x)=SQRT{(x-2)/3)-6 *
g(x) = 2(x – 3)2 + 4
Your answer

Answers

Answer:

g-1(x)=SQRT{(x-4)/2} + 4

Step-by-step explanation:

I assume that the 2 is the exponent so ^ represents exponent

We know your function is g(x)=2(x-3)^2+4

For inverse functions we swap x and y values, note g(x) is like the y value

Isolate for y

y=2(x-3)^2+4

x=2(y-3)^2+4

(x-4)/2 = (y-3)^2

SQRT{(x-4)/2} + 4 = y

Therefore g-1(x)=SQRT{(x-4)/2} + 4

Find the equation of the line.
Use exact numbers.
y =
x+
Can I please get an explanation :)

Answers

Answer:

the equation is in form

y=mx+b where

m=slope

and

b=y-int (the y value for the vertex)

first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5

then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is

y=x+5

Matthew dropped a tennis ball off the roof of 100 foot tall building. The objects height (y) is modeled by the equation below. At what time (t) does the ball hit the ground? Round your answer to the nearest tenth

Answers

Answer:

2 seconds later

Step-by-step explanation:

Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64

The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;

Since y = -16t² + 64

0 = -16t² + 64

16t² = 64

t² = 64/16

t² = 4

t = ±√4

t = 2 and -2

Time cannot be negative, hence the ball hits the ground 2 seconds later.

Note that the equation used was assumed. Similar solution can be applied for any given equation.

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack. The weight of the blue marlin way 12 times as great of the amberjack. The combined weight of both fish was 273 pounds. How much did each fish weight

Answers

Answer:

The weight of the blue marlin = b = 252 pounds

The weight of the amber jack = a = 12 pounds

Step-by-step explanation:

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack.

Let

The weight of the blue marlin = b

The weight of the amber jack = a

The weight of the blue marlin weigh 12 times as that of the amberjack.

b= 12a

The combined weight of both fish was 273 pounds.

= a + b = 273 pounds

b = 12a

Hence

a + 12a = 273 pounds

13a = 273 pounds

a = 273 pounds/13

a = 21 pounds

b = 12a

b = 12 × 21 pounds

= 252 pounds

Hence:

The weight of the blue marlin = b = 252 pounds

The weight of the amber jack = a = 12 pounds

(2+3i)(1-2i)

What is the product of the complex number

Answers

Answer:

(2+3i)(1-2i) = (8-i)

Step-by-step explanation:

The given complex number is :

Z = (2+3i)(1-2i)

We need to find the product of the complex number

[tex]Z=2(1)+2(-2i)+3i(1)-6i^2\\\\=2-4i+3i-6i^2[/tex]

We know that, [tex]i^2=-1[/tex]

[tex]Z=2-i-6(-1)\\\\=2-i+6\\\\=8-i[/tex]

Hence, the product of the complex number is (8-i).

Answers

Answer:

consecutive interior angles equal 180 not equal to each other

Step-by-step explanation:

Answer:

6x− 1 0 = 4 + 4 0

6x-10=4x+40

6x−10=4x+40

Solve

Add

1 0

to both sides of the equation

6 − 1 0 = 4 + 4 0

6x-10=4x+40

6x−10=4x+40

6 − 1 0 + 1 0 = 4 + 4 0 + 1 0

6x-10+{\color{#c92786}{10}}=4x+40+{\color{#c92786}{10}}

6x−10+10=4x+40+10

Simplify

Add the numbers

6 = 4 + 5 0

6x=4x+50

Subtract

4 4x 4x

from both sides of the equation

6 = 4 + 5 0

6x=4x+50

6 − 4 = 4 + 5 0 − 4

6x{\color{#c92786}{-4x}}=4x+50{\color{#c92786}{-4x}}

6x−4x=4x+50−4x

Simplify

Combine like terms

2x=50

Divide both sides of the equation by the same term

2x=50

2 /2 = 5 0 /2

\frac{2x}{{\color{#c92786}{2}}}=\frac{50}{{\color{#c92786}{2}}}

22x=250

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

= 2 5

Solution

= 2 5

Solve for x. 5x - 29> -34 OR 2x +31 < 29

Answers

Answer:

x > -1 or x < -1

Step-by-step explanation:

In this question, you would solve the inequalities.

Solve:

Inequality 1:

5x - 29> -34

Add 29 to both sides

5x > -5

Divide both sides by 5

x > -1

Inequality 2:

2x +31 < 29

Subtract 31 from both sides

2x < -2

Divide both sides by 2

x < -1

Your answer would be: x > -1 or x < -1

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.

Answers

Answer:

Length of side AD is 6.5 units.

Step-by-step explanation:

Let the center of the rectangular base of the given pyramid is O,

From the picture attached,

m∠AOD = 90°

By applying Pythagoras theorem in the right triangle AOD,

AD² = AO² + OD²

AD² = 6² + (2.5)²

AD = √42.25

AD = 6.5 units

Therefore, length of side AD is 6.5 units.
