PLEASEE HELP!!!!!!!!!

Answer: B

Step-by-step explanation:

Answer:

a = 2

b = 1

c = 1

Step-by-step explanation:

The quadratic equation, 2x² + x + 1 = 0, is expressed in the standard form as ax² + bx + c, where a ≠ 0.

Thus,

a = 2

b = 1 (1 * x = x)

c = 1

Answer:

The system has one solution.

Step-by-step explanation:

To find the number of solutions of the system, we equal both equations for y.

If we have ax = b, in which both a and b are different of 0, we have one solution.

If both a and b are 0, we have infinite solutions.

If a is 0 and b is not, there are no solutions.

y=6/7x-8 and y=7/9x+10/9

So

[tex]\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}[/tex]

[tex]\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8[/tex]

[tex]\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}[/tex]

[tex]\frac{5x}{63} = \frac{82}{9}[/tex]

[tex]45x = 63*82[/tex]

Both a and b are different of 0, so the system has one solution.

Answer:

Step-by-step explanation:

The equation of line is y = 3x + 9 , where the slope is m = 3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = 3x + 9   be equation (1)

The equation is of the form y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

Slope m = 3

The y intercept of the line is ( 0 , 9 )

Now , the equation of line is plotted on the graph below

Hence , the equation of line is y = 3x + 9

Answer:

[tex]h = 12[/tex]

[tex]x = 9[/tex]

[tex]y= 16[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

[tex]A = \frac{1}{2} * 15 * 20[/tex]

[tex]i.e\ height = 20[/tex]

[tex]A = \frac{1}{2} * 300[/tex]

[tex]A = 150[/tex]

Let the base of the triangle be 25.

So, the area is:

[tex]A = \frac{1}{2} * 25 * h[/tex]

[tex]i.e\ height = h[/tex]

[tex]A = \frac{1}{2} * 25h[/tex]

Substitute [tex]A = 150[/tex]

[tex]\frac{1}{2}*25h = 150[/tex]

Solve for h

[tex]h = \frac{150 *2}{25}[/tex]

[tex]h = 6 *2[/tex]

[tex]h = 12[/tex]

Considering the smallest triangle

[tex]Hypotenuse = 15[/tex]

So:

[tex]15^2 = h^2 + x^2[/tex]

[tex]15^2 = 12^2 + x^2[/tex]

This gives:

[tex]15^2 - 12^2 = x^2[/tex]

[tex]81 = x^2[/tex]

Take square roots

[tex]9 =x[/tex]

[tex]x = 9[/tex]

Solving for y

[tex]x + y = 25[/tex]

[tex]y= 25 - x[/tex]

[tex]y= 25 - 9[/tex]

[tex]y= 16[/tex]

Answer:

I think its 97.51

Step-by-step explanation:

Area of circle is A = [tex]\pi r^{2} = \pi 6^{2}[/tex]

Area of a triangle is [tex]\frac{\sqrt{3} }{4}a^{2}[/tex] = [tex]\frac{\sqrt{3} }{4}6^{2}[/tex]

Area of triangle = 15.59

Area of circle = 113.1

113.1 - 15.59 = 97.51

Answer:

h(t) = 4.68 seconds

Step-by-step explanation:

The function that represents the height of each firework in feet is :

[tex]h (t) = -16t^2 + 150t + 10.5[/tex] .....(1)

We need to find the time the fireworks take to reach their maximum height. For maximum height,

dh/dt = 0

So,

[tex]\dfrac{d}{dt}(-16t^2 + 150t + 10.5 )=0\\\\-32t+150=0\\\\t=\dfrac{150}{32}\\\\t=4.68\ s[/tex]

Put t = 4.68 in equation (1).

[tex]h (t) = -16(4.68)^2 + 150(4.68)+ 10.5\\\\h(t)=362.06\ text{feet}[/tex]

So, the fireworks will take 4.68 seconds to their maximum height.
