The surface areas of two similar figures are 81 m2 and 121 m2. The volume of the
smaller figure is 2187 m². What is the volume of the larger figure?

Answer:

a=1, b= 7, c=0

Opens upward since a is positive(meaning it has a minimum vertex)

Y-int: (0,0)

Step-by-step explanation:

y=[tex]x^{2}[/tex]+7x

In order to find, the y-intercept, x has to be 0, so plug in 0 for x

y=[tex]0^{2}[/tex]+7(0)

y=0

So the y intercept: (0,0)

The equation form a parabola that opens up and the y intercept is at y = 0. a = 1, b = 7 and c = 0

A quadratic function is in the form:

y = ax² + bx + c

Given that:

y = x² + 7x, hence:

a = 1, b = 7 and c = 0

The equation form a parabola that opens up and the y intercept is at y = 0.

The solution of the equation [tex]x^2 + 3x - 9 = 0[/tex] by completing the square would be [tex]x = \pm ( \dfrac{\sqrt{45}}{2} - \dfrac{3}{2} )[/tex].

Used the concept of a quadratic equation that states,

An algebraic equation with the second degree of the variable is called a Quadratic equation.

Given that the equation is,

[tex]x^2 + 3x - 9 = 0[/tex]

Now completing the square as

[tex]x^2 + 3x - 9 = 0[/tex]

Add and subtract by 9/4,

[tex]x^2 + 3x + \dfrac{9}{4} - \dfrac{9}{4} - 9 = 0[/tex]

[tex]x^2 + 3x + ( \dfrac{3}{2})^2 - \dfrac{9}{4} - 9 = 0[/tex]

[tex](x + \dfrac{3}{2} )^2 - ( \dfrac{9}{4}+ 9) = 0[/tex]

[tex](x + \dfrac{3}{2} )^2 - ( \dfrac{45}{4}) = 0[/tex]

[tex](x + \dfrac{3}{2} )^2 = ( \dfrac{45}{4})[/tex]

Taking square root on both sides,

[tex](x + \dfrac{3}{2} ) = \pm ( \dfrac{\sqrt{45}}{2})[/tex]

Therefore, the solution of an equation is,

[tex]x = \pm ( \dfrac{\sqrt{45}}{2} - \dfrac{3}{2} )[/tex]

Answer:

The solution set for [tex]s<3[/tex] would be (-∞,3)

The solution set for [tex]|s|<3[/tex] would be (-3,3)

Step-by-step explanation:

The solution set for [tex]s<3[/tex] can be any number that is lower than 3.

When we have the inequality  [tex]|s|<3[/tex], we need to rewrite this without the absolute values to find our answer

[tex]|s|<3[/tex]

[tex]s<[/tex] ± [tex]3[/tex]

This can be be split into [tex]s<3, s<-3[/tex]

But, there one thing that needs to be done to the inequality with the-3. As we multiplied it by a -1 to make it negative, we must reverse the sign of the inequality. This leaves us with [tex]s<3, s>-3[/tex]

Now, we can combine these to get one inequality

[tex]-3<s<3[/tex]

Step-by-step explanation:

X-AXIS

when a graph intersects the x-axis, the y value is always 0.  

Ex.  Points (1,0), (-5,0), (-3,0), (6,0), etc. are all on the x-axis because y = 0.  

to find where the graph crosses the x-axis, let y or g(x) = 0

0 = -5^x + 5  subtract 5 from both sides

-5 = -5^x       if x is 1, that would produce -5 = -5

(1,0) x axis

Y-AXIS

when a graph intersects the y-axis, the x value is always 0.

Ex.  Points (0, 1), (0, -2), (0, 3), etc. all lie on the y-axis because x = 0.

to find where teh graph crosses the y-axis, let x = 0

does the exponent "x" apply to (-5) or just 5?  

[tex]-5^{x} or (-5)^{x}[/tex]

(-5)^0 + 5    any number with a 0 power is 1

1 + 5 = 6

(0, 6)

or -5^0 + 5

       -1  +  5 = 4

(0, 4)

Answer:

False

Step-by-step explanation:

In order for the dilated image to become larger, it has to have a scale factor that is more than one not less than one.

False, Because If the scale factor is greater than 1, the image is larger than the preimage.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We know that;

If the scale factor is between 0 and 1, the image is smaller than the preimage. Dilations with a scale factor between 0 and 1 are called reductions.

And, If the scale factor is greater than 1, the image is larger than the preimage. Dilations with a scale factor greater than 1 are called enlargements.

Thus, The given statement is false.

Add 10 on both sides,

9s+10=-10+10s+1

9s+10=10s

Subtract 9s on both sides,

9s+10-9s=10s-9s
