Answer:

Step-by-step explanation:

Given function:

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

The given function has:

Find the value of b:

The function is:

The y-coordinate of the vertex is:

Answer:

Solution given:

y = -x² + bx + 3

we have

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

x = [tex] \frac{ - b}{2a} [/tex]

we have

x = 10, and a = -1

Substituting value of a in -b/2a

we get

b = 20

now

The y-coordinate of the vertex is:

y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

Answer:length of the other piece=39.86m

Step-by-step explanation:

Total length of rope =63.45 m

length of one piece = 23.59 m

Since the rope was cut into two pieces, we subtract the length of  known first piece from the total length

length of the other piece  = 63.45 m-23.59 m=39.86m

Answer:

t=36

Step-by-step explanation:

54-18 = 36

Answer:

t + 18 = 54

Step-by-step explanation:

t + 18 = 54

subtract 18 from both sides

t = 36

The temperature during the night was 36 degrees

Answer:

P = 10x + 2

Step-by-step explanation:

Formula to find perimeter:

P = 2(l + w)

P = 2(4x + 1 + x)

P = 2(5x + 1)

P = 10x + 2

Answer:

In this equation R would equal 88 because it satisfies the equation.

Step-by-step explanation:

You must solve for R by isolating the variable(which is R). To move the 1/8, multiply both sides by 8. You would do this because 8 is the reciprocal of 1/8. With R on it's own, to keep both sides equal multiply 11*8. That equals 88, which satisfies the equation, which is why 88 is the solution.

Hope this helps :)

Answer:

1. A=42

L=14

42=W(14)

divide both sides by 14

3=W

2. A=96

L=12

96=W(12)

divide both sides by 12

8=W

3. A=90

L=18

90=W(18)

divide both sides by 18

5=W

4. A=1.50

L=15

1.50=W(15)

divide both sides by 15

0.1=W

Answer:

The constraints are as follows;

1) 2·x + 2·y ≤ 120

2) 3·x + 4·y ≤ 160

3) x = 2.30

4) y = 3.10

5) P = 2.3·x + 3.10

Step-by-step explanation:

The question is a word problem, with the analysis as follows;

The profit from the roast beef special per sandwich = $2.30

The profit from the turkey special per sandwich = $3.10

The number of slices of bread in the roast beef special = Two slices

The number of slices of cheese in the roast beef special = Three slices

The number of slices of bread in the turkey special = Two slices

The number of slices of cheese in the turkey special = Four slices

The number of slices of bread the deli has  = 120 slices

The number of slices of cheese the deli has = 160 slices

Let 'x' and represent the number of roast beef special and 'y' represent the number of turkey special the deli makes, then we have the constraints as follows;

For the number of slices of bread used;

2·x + 2·y ≤ 120...(1)

For the number of slices of cheese used;

3·x + 4·y ≤ 160...(2)

x = 2.30

y = 3.10

The profit 'P' is given by the following equation

P = 2.3·x + 3.10.

Answer:

11749

Step-by-step explanation:

i) Area = length x width

=250 x 100

= 25000 cm2

ii) it is a square so the sides are equal

Area = 10 x 10

= 100cm2

iii) 25000/100

250 tiles will be needed

Iv) one tile is 4.75 dollars

Total tiles are 250

Cost for tiling

=250 x 4.75

=1187.5
