Answer 1

Answer:

11

Step-by-step explanation:

x= -b/2a

x= -8/2(-2)

x=-4/-2

x=2

f(2) = -2(2) +8(2)+ 3

f(2) = -8 +16 + 3

f(2) = 11

Maximum value is 11

Answer 2

Answer:

11

Step-by-step explanation:

it has a vertex at (2,11)

.

f(2) = 11

how to find the vertex;

function equation is f(x) = ax^2 + bx + c

we can find x by :-b/2a, -8/-4 = 2

and by putting the x value we get the y

f(2) = 11

Mike 24 coins in nices and dimes they are valued at $2.05. how many DIMES does he have?​

Answers

Answer: He has 8 dimes

Step-by-step explanation:

Answer:

17 dimes

7 nickels

Step-by-step explanation:

n = number of nickels

d = number of dimes

0.10d + 0.05n = 2.05

n + d = 24, n = 24 - d

substitute for n:

0.10d + 0.05(24 - d) = 2.05

simplify:

0.10d + 1.20 - 0.05d = 2.05

0.05d = 0.85

d = 17

n = 24-17 = 7

Answer:

C = 150.72 cm

A = 1808.64 [tex]cm^{2}[/tex]

Step-by-step explanation:

circumference = 2π[tex]r[/tex]

r = 24 (48 ÷ 2)

substitute 24 for r

C = 2 × 3.14 × 24

C = 150.72

Area = π[tex]r^{2}[/tex]

r = 24

substitute 24 for r

A = 3.14 × [tex]24^{2}[/tex]

A = 3.14 × 576

A = 1808.64

circumference = π x d
= 3.14 x 48
= 150.72 cm

radius =48 divide by 2
= 24
area = π x r x r
= 3.14 x 24 x 24

a rectangular playground has its length more than its breath by 2 m find the length and breadth of the playground if area of playground is 440 sq.m.​

Answers

Answer:

Length = 22m

Breadth = 20m

Step-by-step explanation:

Given:

Area = 440 m²

Let the breadth be x m

According to the question:

Length = (x+ 2) m

Area of a rectangle = length × breadth

Substitution the values of area, length and breadth

440 = (x+2) × x

440 = x² + 2x

x² + 2x - 440 = 0

x² + 22x - 20x - 440 = 0

x (x + 22) - 20 (x + 22) = 0

(x + 22)  (x - 20) = 0

x = -22 and 20

Since the value of breadth cannot be in negative, therefore the value of breadth will be 20 m.

Length = (x + 2)

⇒ 20 + 2

⇒ 22 m
