Find the value of x. ​

Answer:

y=-0.215x^2+35

Step by Step:

Let, [tex]h=0[/tex],  [tex]k=35[/tex], [tex]x=8[/tex], [tex]y=21[/tex]

We know that, the general equation of the parabola.

   [tex]y-k = a(x-h)^2[/tex]

[tex]\Rightarrow y=a(x-h)^2+k .........(i)[/tex]

Substitute the  value of [tex]h, k, x, y[/tex] in equation [tex](i)[/tex] and find the value of [tex]a.[/tex]

  [tex]21=a(8-0)^2+35[/tex]

[tex]\Rightarrow 21=a\times 8^2+35[/tex]

[tex]\Rightarrow 21=64a+35[/tex]

[tex]\Rightarrow 64a=21-35[/tex]

[tex]\Rightarrow 64a=-14[/tex]

[tex]\Rightarrow a=\frac{-14}{65}[/tex]

[tex]\Rightarrow a=-0.215[/tex]

Hence, the equation of the parabola is:

[tex]y=-0.215x^2+35[/tex]

Answer: X-intercept is (2,0)

Y-intercept is (0,-2)

Step-by-step explanation:

Answer:

X-intercept is (2,0)

Y-intercept is (0,-2)

Step-by-step explanation:

The x intercept is the point at which the line hits the x-axis

in this picture, you can see that the given line hit the x-axis at (2,0)

The y intercept is the point at which the line hits the y-axis

so in this case you can see the the line hits the y-axis at (0,-2)

Bonus: if a line is horizontal it will not have an x intercept, and if a line is vertical, it will not have ay intercept

Answer:

[tex]T(ln2)[/tex][tex]= <\sqrt{145} , \frac{6\sqrt{2} }{\sqrt{145} } , \frac{6\sqrt{2} }{\sqrt{145} } >[/tex]

Step-by-step explanation:

Given : [tex]r(t)=<7-\sqrt{e^t}, 3e^t,3e^t > .........(i)[/tex]

We first have to differentiate of equation [tex](i)[/tex]

[tex]r'(t) = < \frac{\sqrt{e^t} }{2} , 3e^t,3e^t> ..........(ii)[/tex]

Now to get a unit tangent vector at the given value of [tex]t[/tex], we put [tex]t = ln2[/tex] in equation [tex](ii)[/tex]

[tex]r'(ln2) = < \frac{\sqrt{e^{ln2}} }{2} , 3e^{ln2},3e^{ln2}>[/tex]

            [tex]= <\frac{1}{\sqrt{2} } ,6,6>[/tex]        [∵[tex]e^{lna}=a[/tex]]

Now to get a unit tangent vector , we will divide our vector [tex]r'(ln2)[/tex] by its magnitude. So let's first find the magnitude.

[tex]|r'(ln2)|=\sqrt{(\frac{1}{\sqrt{2} } )^2 +6^2+6^2}[/tex]

             [tex]= \sqrt{\frac{1}{2}+36+36 }[/tex]

             [tex]= \sqrt{\frac{145}{2} }[/tex]

Now we can find the our unit tangents vector.

      [tex]T(ln2)=\frac{r'(ln2)}{|r'(ln2)|}[/tex]

                  [tex]= \frac{<\frac{1}{\sqrt{2}} ,6,6> }{\sqrt{\frac{145}{2}} }[/tex]

                  [tex]= <\frac{\frac{1}{\sqrt{2} } }{\sqrt{\frac{145}{2}} } ,\frac{6}{{\sqrt{\frac{145}{2}} }}, \frac{6}{{\sqrt{\frac{145}{2}} }} >[/tex]

                   [tex]= <\sqrt{145} , \frac{6\sqrt{2} }{\sqrt{145} } , \frac{6\sqrt{2} }{\sqrt{145} } >[/tex]

Hence, [tex]T(ln2)[/tex] [tex]= <\sqrt{145} , \frac{6\sqrt{2} }{\sqrt{145} } , \frac{6\sqrt{2} }{\sqrt{145} } >[/tex]

Answer: pretty sure its 85

Step-by-step explanation:

Answer:

85°

Step-by-step explanation:

Line segment AB || line m

Therefore, BC is transversal.

[tex] \therefore m\angle ABC + (m\angle ACB +m\angle A D) = 180\degree[/tex]

[tex] \therefore m\angle ABC + (55\degree + 40\degree) = 180\degree[/tex]

[tex] \therefore m\angle ABC + 95\degree = 180\degree[/tex]

[tex] \therefore m\angle ABC = 180\degree -95\degree [/tex]

[tex] \therefore m\angle ABC = 85\degree [/tex]

The answer is A

Answer:

[tex]Scale\ Factor = \frac{1}{2}[/tex]

ABC dilated

Step-by-step explanation:

Given

Triangles ABC and DEF

Required

Determine the scale of dilation

First, we pick a side on ABC

[tex]AB = 6[/tex]

Pick a corresponding side on DEF

[tex]DE = 3[/tex]

The scale factor is then calculated as:

[tex]Scale\ Factor = \frac{DE}{AB}[/tex]

[tex]Scale\ Factor = \frac{1}{2}[/tex]

i.e. ABC was dilated by 1/2

Answer:

y=1/2x-2

Step-by-step explanation:

perpendicular lines have a neg. reciprocal for the slope.

for example:

in this equation y=-2x+1

-2 is the slope and the negative reciprocal would be 1/2

hence, the slop of our new line is 1/2

y=1/2x+b

we can substitute the coordinates given for x and y:

2=1/2(8)+b

2=4+b

-2=b

hence the new equation is y=1/2x-2

Answer:X^12

Step-by-step explanation:

Hey there!

“ (x⁴)³ ”

(x⁴) = x⁴ • x⁴ • x⁴

x⁴ = (x • x • x • x) * (x • x • x • x) * (x • x • x • x)

Number of x’s is 12

3 • 4 = 12, right?

Answer:

-6

Step-by-step explanation:

-3a + 4 = -14

-3a = -14 - 4

-3a = -18

a = -18 / 3

a = -6

Answer:

a = 6

Step-by-step explanation:

Step 1: Subtract 4 from both sides.

-3a + 4 - 4 = -14 - 4

+4 and -4 cancel out.

Step 2: Subtract 4 from -14 to get -18.

-3a = -18

Step 3: Divide both sides by -3.

a = -18/-3

Step 4: Divide -18 by -3 to get 6.

a = 6

Let's check our work by substituting a for 6.

-3(6) + 4 = -14

Multiply -3 by 6 to get -18.

-18 + 4 = -14

Add -18 and 4 to get -14.

-14 = -14

This is true, so a = 6.

Answer:

m = 136

Step-by-step explanation:

m/8 - 5 = 12

1. Add 5 on both sides

m/8 - 5 + 5 = 12 + 5

m/8 = 17

Multiply 8 on both sides since u are trying to isolate the variable

m/8 * 8 = 17*8

m = 136

Check

136/8 - 5 = 12

17 - 5 = 12

12 = 12

Hope it helped!

Step-by-step explanation:

[tex]\frac{m}{8}[/tex] - 5 = 12 : Original Problem

[tex]\frac{m}{8}[/tex] -5 +5 = 12 + 5 : Bringing the constants to one side

[tex]\frac{m}{8}[/tex] = 17 : Simplification

[tex]\frac{m}{8}[/tex]×8 = 17×8: Isolating the variable

m = 136 : The answer!!!

Checking the answer

[tex]\frac{136}{8}[/tex] -5 = 12 : Substitution

[tex]\frac{136}{8}[/tex] = 17 : Bringing constants to one side and simplification

136 = 17 × 8 : Isolating the answer

136 = 136 : Success!!!

I hope this is what you wanted and I hope this helps!!!

uh- this is the correct way to answer the problem....

−4x+12=−6x

Step 1: Add 6x to both sides.

−4x+12+6x=−6x+6x

2x+12=0

Step 2: Subtract 12 from both sides.

2x+12−12=0−12

2x=−12

Step 3: Divide both sides by 2.
