Answer 1

Answer:

(9.2 , 0)

Step-by-step explanation:

vertex: (4.6 , 12.2)

parabola: y = a (x-4.6)² + 12.2

pass (0,0):  0 = a (0-4.6)² + 12.2

a = - (12.2/21.16)

2nd root (x , 0):  y=0

0 = a (x-4.6)² + 12.2           (x-4.6)² = - 12.2 / a = -12.2 / (- (12.2/21.16)) = 21.16

x - 4.6 = ± √21.16 = ± 4.6

x = 0 or x = 9.2

Answer:

AY = 4.8YD = 2.4

Step-by-step explanation:

Corresponding sides of the triangles are ...

  ΔFUN  . . .   ΔDAY

  UF = 10 . . .  AD = 6

  FN = 4 . . .  DY

  NU = 8 . . .  YA

Corresponding sides are proportional, so we have ...

  DY/4 = AD/UF = 6/10

  DY = 4(0.6) = 2.4

and

  YA/8 = 6/10

  YA = 8(0.6) = 4.8

The side lengths are ...

  AY = 4.8, YD = 2.4

The area if a rectangular frame is 32 square inches. The perimeter of the frame is 24 inches. Which shows the correct dimensions of the frame?

Answers

Answer:

8 x 4

Step-by-step explanation:

Lets say the length is x and the width is y.

xy = 32

2x + 2y = 24

Rearranging the second equation, we get:

2x = 24 - 2y

/2         /2

x = 12 - y

substitute into the first equation

y(12 - y) = 32

12y - y^2 = 32

-32             -32

-y^2 +12y - 32 = 0

x -1                      x -1

y^2 - 12y + 32 = 0

(y - 8)(y - 4) = 0

y = 8 or 4

substitute into x = 12 - y.

x = 12 - 8 = 4

x = 12 -4 = 8

so the correct dimensions are 4 x 8, as either x = 4 and y =8, or x = 8 and y = 4.

6/10
because if u divide 6 by 2, u get 3
and divide 10 by 2 to get 5
so 6/10 is equivalent

Answer:

6/10

Step-by-step explanation:

6/10 is equal to 3/5 because you can multiply 3/5 times 2. So multiply the numerator(3) times 2, which is 6, then multiply the denominator(5) times 2 as well, which is 10.

Hope this helped!

Do not factor by grouping. Solve 2(x-2)^1/3=x+2

Answers

Step-by-step explanation:

2(x-2)⅓=x+2

so we first cube each side,such that...

(2(x-2))⅓•³=(x+2)³

we get...

2(x-2)=(x+2)³

expanding...

2x-4=x³+6x²+12x+8

grouping....

x³+6x²+12x+8-2x+4=0

solving...

x³+6x²+10x+12=0

now you can use you calculator to solve for the possible values of x

I hope this will help

a girl 2.2m tall observes that the angle of elevation of the top of a building 16m away from her is 45° find the height of the building​

Answers

Answer:

18.2 m = height of the building

Step-by-step explanation:

Let x = the distance from the top of the girl's head to the top of the building

tan 45 = x/16

x = 16 tan 45

x = 16 m

16 + 2.2 = 18.2 m = height of the building

Round your answer to three places.

Answers

Answer:

[tex]x=0.61485921[/tex]

Step-by-step explanation:

The given equation is in exponential form:

[tex]6^{4x} =82[/tex]

To find [tex]x[/tex] we need to write it in logarithmic form:

[tex]b^{a} =n[/tex] ⇒ [tex]log_{b} n=a[/tex]

[tex]6^{4x} =82[/tex] ⇒ [tex]log_{ 6 } 82=4x[/tex]

           [tex]2.45943684 = 4x[/tex]

              [tex]\frac{2.45943684}{4} = x[/tex]

           [tex]0.61485921 =x[/tex]

To prove this, we can substitute the value into the given equation

             [tex]6^{4x} =82[/tex]

[tex]6^{4(0.61485921)} =82[/tex]

               [tex]82=82[/tex]

Therefore, the answer is [tex]x=0.61485921[/tex]
