Answer:

16 dimes

Step-by-step explanation:

D=number of dimes

Q=number of quarters

D+Q=37

.25 xQ + .10 x D=6.85

sub Q from first equation

.25(37-D) + .10 x D=6.85

D(.10-.25) + .25 x 37 =6.85

-.15D + 9.25=6.85

D= (6.85-9.25)/(-.15)

D=16

Answer:

Step-by-step explanation:

area of square is basically one side times itself

14 times 14 =196m^2

Answer: 196 meters

Step-by-step explanation: To find the area of any square you must do length(vertical side) times the width(horizontal side). It would look like this: length x width. So in this equation, it would be 14x14=the area. Another thing is that when you have a square when you know one side the other side is always as long or wide as the one you know. So 14x14=196 square meters

Answer:

5 weeks

Step-by-step explanation:

so if Lily has $60 and takes out (subtracts) 12 a week then it would look like this

    TOTAL STARTED WITH       EACH WEEK

          $60                  -12              48

         $48               -     -12           36

         $36                      -12          24

           $24                  -12          12

          $12                   -12           0

SO Lily will have enough money to deposit for 5 weeks

Answer:

Cost of pop = $2

Cost of snacks = $3

Step-by-step explanation:

Let

Cost of pop = x

Cost of snacks = y

Hauler

x + 4y = 14

Good

2x + 2y = 10

x + 4y = 14 (1)

2x + 2y = 10 (2)

Using elimination method

Multiply (1) by (2)

2x + 8y = 28 (3)

2x + 2y = 10 (2)

Subtract (2) from (3) to eliminate x

8y - 2y = 28 - 10

6y = 18

y = 18/6

y = $3

Substitute y = 3 into (1)

x + 4y = 14 (1)

x + 4(3) = 14

x + 12 = 14

x = 14 - 12

x = $2

Cost of pop = $2

Cost of snacks = $3

Answer:

12

Step-by-step explanation:

Answer:

18

Answer:

2.5

Step-by-step explanation:

The computation of the XW is shown below

As triangle UVX is a right angle

So

VU^2 = XU^2 - VX^2

VU^2 = 15.7^2 - 8.5^2

VU^2 = 246.49 - 72.25

VU^2 = 174.24

VU = 13.2

As VU = WX because of same point tangent

NOw XW is

= UX - UW

= 15.7 - 13.2

= 2.5

Answer:

Step-by-step explanation:1) Find the domain of the given function. f(x) = square root of quantity x plus three divided by quantity x plus eight times quantity x minus two.

using a graphical tool    see the attachment  

the answer is C) x ≥ -3, x ≠ 2  

2. Identify intervals on which the function is increasing, decreasing, or constant.

g(x) = 2 - (x - 7)2

using a graphical tool    

see the attachment

the answer is  C) Increasing: x < 7; decreasing: x > 7

3. Perform the requested operation or operations.

f(x) = 4x + 7, g(x) = 3x2

Find (f + g)(x).

(f + g)(x) = f(x) + g(x)

(f + g)(x) = 4x + 7 + 3x^2

(f + g)(x) = 3x^2 + 4x + 7

The answer is  C) 4x + 7 + 3x2

4. Perform the requested operation or operations.

f(x) = x minus five divided by eight. ; g(x) = 8x + 5, find g(f(x)).

f(x)=(x-5)/8    g(x)=8x+5

g(f(x))=8((x-5)/8)+5=x-5+5=x

the answer is  B) g(f(x)) = x  

5. Find f(x) and g(x) so that the function can be described as y = f(g(x)).y = nine divided by square root of quantity five x plus five.

y=f(g(x))=9/((5x+5) ^1/2)

let do

g(x)=5x+5...........so

f(x)= 9/( x^1/2)

the answer is  A) f(x) = nine divided by square root of x. , g(x) = 5x + 5

6. A satellite camera takes a rectangular-shaped picture. The smallest region that can be photographed is a 4-km by 4-km rectangle. As the camera zooms out, the length l and width w of the rectangle increase at a rate of 3 km/sec. How long does it take for the area A to be at least 4 times its original size?

Original size- >4km*4km=16 km2

4 times its original size---------------4*(16km2)-----64 Km2----------- > 8 km by 8 Km

Therefore

3km----------------------------- 1 sec

(8km-4km)---------------------x

X=4/3=1.33 sec

The answer is D) 1.33 sec

7. Find the inverse of the function.

f(x) = the cube root of quantity x divided by seven. - 9

to solve, replace f(x) with y , switch x and y, solve for y and replace y with f⁻¹(x)

f(x)=((x/7)-9) ^(1/3)

replace f(x) with y

y=((x/7)-9) ^(1/3)

switch x and y

x=((y/7)-9) ^(1/3)

solve for y

x^3=((y/7)-9)

x^3+9=y/7

y=7(x^3+9)

the answer is C) f-1(x) = 7(x3 + 9)  

8. Describe how the graph of y= x2 can be transformed to the graph of the given equation.y = (x - 14)2 – 9

using a graphical tool     see the attachment  the answer is C) Shift the graph of y = x2 right 14 units and then down 9 units  

9. Describe how to transform the graph of f into the graph of g. f(x) = alt='square root of quantity x minus nine.' and g(x) = alt='square root of quantity x plus five. '

f(x)=(x-9) ^1/2  g(x)=(x+5) ^1/2

using a graphical tool     see the attachment

the answer is C) Shift the graph of f left 14 units

a=1,b=4,c=7

Consider the vertex form of a parabola.

a(x+d)2+e

Find the value of dd using the formula d=b/2a

d=4/(2*1)=2

Answer:

Chocolate Sauce: 4/8

Strawberry Sauce: 2/8

Caramel Sauce: 2/8

Chocolate Sauce

Monday, the shop had 7/8, the shop used 3/8 on Tuesday. So we subtract the numerators but the denominator stays the same.

7 - 3 = 4

So it is 4/8

Same thing for Strawberry and Caramel Sauce.

So we add the totals we got from subtracting Monday amount of toppings with Tuesday's amount of toppings.

4/8 + 2/8 + 2/8 =

Answer:

15x2+10x-9x+7

8x3+20x2+3x+12

11x4+4x2-6x2-16

Step-by-step explanation:

The prime polynomials are;

⇒ 15x² + 10x – 9x + 7

⇒ 8x³ + 20x² + 3x + 12

⇒ 11x⁴ + 4x² – 6x² – 16

What is an expression?

Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

There are some polynomials.

Now,

Evaluate all options in order to check that the polynomials are prime or not as;

Since, The polynomial is called a prime polynomial if the polynomial has not lower degree factors.

1). 15x² + 10x – 9x + 7

15x² + 10x – 9x + 7 = 5x(3x + 2) - (9x - 7)

Thus, This polynomial can not be factored into lower degree polynomial. Hence, it is a prime polynomial.

2). 20x² - 12x + 30x - 18

20x² - 12x + 30x - 18 = 4x (5x - 3) + 6 (5x - 3)

                                = (4x + 6) (5x - 3)

Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

3). 6x³ + 14x² - 12x - 28

6x³ + 14x² - 12x - 28 = 2x² (3x + 7) - 4(3x + 7)

                               = (2x² - 4) (3x + 7)

Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

4). 8x³ + 20x² + 3x + 12

8x³ + 20x² + 3x + 12 = 4x² (2x + 5) + 3 (x + 4)

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

Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

5). 11x⁴ + 4x² – 6x² – 16

11x⁴ + 4x² – 6x² – 16 = x² (11x² + 4) - 2 (x² + 8)

Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

Therefore, The prime polynomials are;

⇒ 15x² + 10x – 9x + 7

⇒ 8x³ + 20x² + 3x + 12

⇒ 11x⁴ + 4x² – 6x² – 16
