Answer:

25

Step-by-step explanation:

At x = 10 and 31 the value of the function h(x) is greater than g(x) thus options (A) and (D) are correct.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given graph of the function,

At x = 10 the h(x) > g(x)

At x = 31 the h(x) > g(x)

Hence "The value of the function h(x) is bigger than g(x) at x = 10 and 31".

Step-by-step explanation:

A = 3(6) + 2(5 + 3 + 2) = 38 m²

Answer:

25 miles/hour

Step-by-step explanation:

If you were to divide 125 by 5, you would get 25 miles per each hour as your answer. Brainless if I am correct.

Step-by-step explanation:

Please this is a wrong question. If you mean square root of 100 then it's 10. As for -100, it's an error.

Answer:

Step-by-step explanation:

P = (-4, 3)

Reflecting across the y axis negates the x value

P₁ = (4, 3)

Reflecting across the x axis negates the y value

P' = (4, -3)

Answer:

i think it is 65

Step-by-step explanation:

the 4th cube number is 64 and the first square number is 1 64+1=65

however if you use the first square number as 4 then it is 68

Step-by-step explanation:

sum was the first name of integral

and the median is something in the middle

for example :

A . B . C

the median is B

Find number of miles driven in one hour:

144 miles / 2 1/4 hours = 64 miles per hour

Multiply by 6 hours:

64 x 6 = 384 miles

Answer: 384 miles

When sum of two angles is 90°, then each of those two angles will be considered to be the complementary angle of each other.Example : 60° and 30° are two angles, and their sum is 90°. So, 60° and 30° are complementary angles.

Answer:

A is correct

Step-by-step explanation:

Given that

(2a+b,11) and (1,a-3b) are equal ordered pair

⇛(2a+b,11) = (1,a-3b)

On comparing both sides then

2a+b = 1 ----------Eqn(1)

11 = a-3b

⇛ a-3b = 11 ------Eqn(2)

⇛ a = 11+3b-------Eqn(3)

On substituting the value of a in Eqn(1) then

⇛ 2(11+3b) + b = 1

⇛(2×11)+(2×3b) + b = 1

⇛ 22 +6b+b = 1

⇛ 22+7b = 1

⇛ 7b = 1-22

⇛ 7b = -21

⇛ b = -21/7

⇛ b = -3

On substituting the value of b in Eqn(3) then

⇛ a = 11+3(-3)

⇛ a = 11-9

a = 2

Therefore, a = -3 and b = 2

Answer:-The value of (a,b) for the given problem is (-3,2).

Answer: C. -12 - 3 + 9

Step-by-step explanation:

-12 because the fish are 12 m below the ocean.

-3 because the fish swim down.

+9 because the fish swim up.

the formula for area of a triangle is 1/2 times the base (4 cm) times the height (5 cm) so the area of the triangle would be 10 cm. to find the area of the rectangle you would divide 10 by 4, which means that w=2.5 cm

Answer:

[tex]2916^3\\[/tex]

Step-by-step explanation:

As the formula is [tex]\frac{4}{3}\pi \cdot r^3[/tex]

But we take [tex]\pi[/tex] as 3 so it would be [tex]\frac{4}{3}3\cdot r^3[/tex]

And the radius is 9 half of Diameter

We would write it like this

=  [tex]\frac{4}{3}3\cdot 9^3[/tex]

Then when we solve it would become [tex]2916^3\\[/tex]

Answer:

[tex]x=-2,y=4[/tex]

Step-by-step explanation:

[tex]y=-x^2-3x+2[/tex]

[tex]y=x+6[/tex]

[tex]x+6=-x^2-3x+2[/tex]

[tex]x^2+x+6=-3x+2[/tex]

[tex]x^2+4x+6=2[/tex]

[tex]x^2+4x+4=0[/tex]

[tex](x+2)(x+2)=0[/tex]

[tex]x=-2[/tex]

[tex]y=(-2)+6=4[/tex]
