Answer:

D. 40.0km

Step-by-step explanation:

When rounding to 3 significant figures, we will have to look at the 4th significant figure. If that figure is 1-4, you round the 3rd figure down. If that figure is 5-9, you round the 3rd figure up.

In this case, the 3rd figure is the tenth 9 and the 4th figure is the hundredth 7.

Since 7 is from 5-9, you round the tenth 9 up. This adds one whole to 39, which makes it 40. You also need to keep 3 significant figures so the decimal zeros are significant. Thus, the answer is 40.0km

Step-by-step explanation:

For an absolute value function, the graph will look like an arrow with a sharp inflection point.

Reciprocal function will tend towards a limit when stretched to infinity.

Cube root and square root functions do not tend towards infinity at x = 0, because it is either 0 or the constant value.

The best answer here is Reciprocal. (B)

Answer:

Step-by-step explanation:

The graphed is the function y = 1/x, it is an odd function and the graph is hyperbola

The function is reciprocal

Correct option is B

Answer:

The equation that will satisfy x and y values in the table is y = 2x + 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

From the given table

∵ x = 0 and y = 3, x = 1 and y = 5

∴ x1 = 0 and x2 = 1

∴ y1 = 3 and y2 = 5

→ Substitute them in the rule of the slope above

∵ m = [tex]\frac{5-3}{1-0}[/tex] = [tex]\frac{2}{1}[/tex]

∴ m = 2

∵ b is the value of y at x = 0

∵ y = 3 at x = 0

∴ b = 3

→ Substitute the values of m, b in the form of the equation above

∴ y = 2x + 3

∴ The equation that will satisfy x and y values in the table is y = 2x + 3

p = √24

Step-by-step explanation:

5² = 1² + p²

25 - 1 = p²

p² = 24

p = √24

Answer:

$120

Step-by-step explanation:

They have raised $780 and need to raise $900.

(Total amount they need to raise) - (total amount they raised) = (how much more they need to collect)

$900 - $780 = $120

Answer:

the possible side lengths:

3x+4 and x-3

Step-by-step explanation:

factorize the the expression and you will get two expressions in terms of x. those expressions are the lengths of the rectangle

[tex]3 {x}^{2} - 5x - 12[/tex]

1) write -5x as a difference

[tex]3 {x}^{2} + 4x - 9x - 12[/tex]

2) factor out x from the expression 3x²+4x

[tex]x(3x + 4) - 9x - 12[/tex]

3) factor out -3 from the expression -9x-12

[tex]x(3x + 4) - 3(3x + 4)[/tex]

4) factor out 3x+4 from the expression

[tex](3x + 4)( x - 3)[/tex]

the possible lengths are 3x+4 and x-3

to check whether the answer is correct, you can just multiply the both lengths using the area of rectangle formulae

area of rectangle formulae

[tex]length \times height[/tex]

(3x+4)(x-3)

= 3x²-9x+4x-12

= 3x²-5x-12 ( proven )

Answer:

Sink

Step-by-step explanation:

We need to find if an object with a certain density will float or sink in water.

The object will sink in water.

The density of the object is 3.6 g/mL

The density of water is generally [tex]1000\ \text{kg/m}^3[/tex]

An object which has a density more than the liquid it is in then the object will sink.

Let us convert the density of the object to [tex]\text{kg/m}^3[/tex]

[tex]1\ \text{g}=10^{-3}\ \text{kg}[/tex]

[tex]1\ \text{mL}=10^{-6}\ \text{m}^3[/tex]

[tex]1\ \text{g/mL}=\dfrac{10^{-3}}{10^{-6}}=10^3\ \text{kg/m}^3[/tex]

[tex]3.6\ \text{g/mL}=3.6\times 10^3=3600\ \text{kg/m}^3[/tex]

The density of the object [tex](3600\ \text{kg/m}^3)[/tex] is greater than that of water [tex](1000\ \text{kg/m}^3)[/tex].

Hence, the object will sink.

The remainder of the division of polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) is; -23

The remainder of the division of the polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) can be evaluated by the remainder theorem.

This involves adding evaluating the value of the polynomial at, x = -2.

Therefore, we have;

Therefore, the remainder when P(x) = 2x3 – x2 + 4x + 5 is divided by (x + 2) is; -23
