Answer:

80%

Step-by-step explanation:

using equivalent fractions:

40/50 = 80/100 = 80%

also since 50 is half of 100 (in other words 100%), you can just multiply 40 by 2 to get a number out of 100 which is your percentage

The equation represents the line that passes through (–6, 7) and (–3, 6) [tex]\rm y=\dfrac{-1}{3}x+5[/tex].

For all lines in slope y-intercept form, it would be very simple to just find the answer by finding yourself the slope and y-intercept of the line in question.

The slope of the line is;

[tex]\rm m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m =\dfrac{7-6}{-6-(-3)}\\\\m = \dfrac{1}{-3}[/tex]

The equation represents the line that passes through (–6, 7) and (–3, 6) is;

[tex]\rm y=\dfrac{-1}{3}x+b\\\\6=\dfrac{-1}{3}(-3)+b\\\\6=1+b\\\\b = 6-1\\\\b=5[/tex]

The required line of the equation is;

[tex]\rm y =mx+c\\\\y=\dfrac{-1}{3}x+5[/tex]

Hence, the equation represents the line that passes through (–6, 7) and (–3, 6) [tex]\rm y=\dfrac{-1}{3}x+5[/tex].

[tex]v_{f}^{2}= 0 + 2*9.8 * 45[/tex]

    = 882 m

[tex]\bold{\huge{\underline{ Answer }}}[/tex]

Here, We have

By using second equation of motion

[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]

Subsitute the required values,

[tex]\sf{ 20 = 0{\times}2 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}a(2)^{2}}}[/tex]

[tex]\sf{ 20 = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4a}}[/tex]

[tex]\sf{ 20 = 2a }[/tex]

[tex]\sf{ a = }{\dfrac{ 20}{2}}[/tex]

[tex]\sf{ a = 10\:m/s^{2}}[/tex]

Hence, The acceleration of the jeepeny is 10 m/s² .

Here, we have

Therefore,

By using second equation of motion

[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]

Subsitute the required values,

[tex]\sf{ S = 0{\times}3 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(3)^{2}}}[/tex]

[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(9)}}[/tex]

[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}36}}[/tex]

[tex]\sf{ S = 18 \: m }[/tex]

Hence, The coin will reach 18 m after 3 seconds.

Here,

So,

By using third equation of motion

[tex]\sf{ v^{2} = u^{2} + 2gs }[/tex]

Subsitute the required values,

[tex]\sf{ v^{2} = 0^{2} + 2{\times}9.8{\times}45 }[/tex]

[tex]\sf{ v^{2} = 90{\times}9.8}[/tex]

[tex]\sf{ v^{2} = 882 m}[/tex]

[tex]\sf{ v = \sqrt{882} m}[/tex]

[tex]\sf{ v = 29.7 m/s}[/tex]

Hence, The final velocity of the stone when the stone hits the ground is 29.7 m.

Given that radius of the sphere is 6 miles. To find Volume of the sphere we will substitute the Value of radius in the given formula:

[tex] \\ \: \: \dashrightarrow { \underline{ \boxed { \pink{ \pmb{ \mathfrak {Volume_{(Sphere)} = \dfrac{4}{3} \pi r ^3 }}}}}} \\ \\ [/tex]

Substituting the required values:

[tex] \\ \: \: \dashrightarrow \sf \: \: Volume = \dfrac{4}{3} \times 3.14 \times {(6)}^{3} \\ \\ [/tex]

[tex] \: \: \dashrightarrow \sf \: \: Volume = \dfrac{4}{3} \times 3.14 \times 216 \\ \\ [/tex]

[tex] \: \: \dashrightarrow \sf \: \: Volume = \dfrac{4}{3} \times 678.24 \\ \\ [/tex]

[tex] \: \: \dashrightarrow \sf \: \: Volume = \dfrac{2712.96}{3} \\ \\ [/tex]

[tex] \: \: \dashrightarrow \sf \: \: { \underline{ \boxed{ \pink{ \pmb{ \mathfrak{Volume \approx 904.3 \: {mi}^{3} }}}}}} \\ \\ [/tex]

Hence,

Step-by-step explanation:

Given :-

To find =

Solution =

Volume of sphere = 4/3 πr³

putting the known values ,

Volume = 4/3 × 3.14 × 6³ mi³

Volume = 904.32 mi³

rounding off to nearest tenth ,

Volume = 904.3 mi³

The true statements about the graph y = 4x2 + 28x + 49 are as follows;

(b) The equation 2x + 7 = 0 can be used to find a zero of the function.

(d) The graph has a double root at x = -7/2.

(e) The graph intersects the y-axis at y = 49.

The graph of a function f is the graph of the equation y = f (x).

The function is given as:

[tex]\rm y = 4x^2 + 28x + 49[/tex]

Express 28x and 14x + 14x; so, we have:

[tex]\rm y = 4x^2 + 14x+14x + 49[/tex]

Factorize

[tex]\rm y = 4x^2 + 14x+14x + 49\\\\y = 2x(2x+7)+7(2x+7)\\\\y=(2x+7)(2x+7)[/tex]

Express as a perfect square

[tex]\rm y = (2x+7)^2[/tex]

This means that the graph of the equation has a double root.

It also means that 2x + 7 = 0 can be used to determine the root/zero of the function.

Substitute 0 for x in to determine the y-intercept

[tex]\rm y = (2x+7)^2\\\\\rm y = (2(0)+7)^2\\\\\rm y = (0+7)^2\\\\y=49[/tex]

This means that the graph intersects with the y-axis at y = 49

Hence, the true statements are (b), (d), and (e)
