Answer: 700.012

Explanation:

1) You must learn and practice the place names and place values as much for whole numbers as for decimal numbers:

i) Whole numbers:

Millions - 1,000,000

Hundred thousands - 100,000

Ten thousands - 10,000

Thousands - 1,000

Hundreds - 100

Tens - 10

Ones - 1

ii) Decimals

Tenths - 1 / 10 = 0.1

Hundredths - 1/ 100 = 0.01

Thousandths - 1 / 1,000 = 0.001

Ten thounsandths - 1 / 10,000 = 0.0001

2) Seven hundred = 7 × 100 = 700

3) Twelve thousandths = 12 / 1,000 = 0.012

4) Seven hundred and twelve thousandths = 700 + 0.012 = 700.012

Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)

alexira [117]

Answer: $x^2-5x=-12(y+2)$

Step-by-step explanation:

Given

Parabola has x-intercept has $(3,0)$ and $(8,0)$

and Y-intercept as $(0,-2)$

Now the general equation of parabola is

$y=ax^2+bx+c\quad \ldots(i)$

Substitute $(0,-2)$ in $(i)$ we get

$-2=c$

Now substitute $(3,0)$ in equation $(i)$

$0=a(3)^2+3b-2\quad \ldots(ii)$

Now substitute $(8,0)$ in equation $(i)$

$0=a(8)^2+8b-2\quad \ldots(iii)$

Solving $(ii)$ and $(iii)$ we get

$a=\frac{-1}{12}\ \text{and}\ b=\frac{5}{12}$

therefore

$y=\frac{-x^2}{12}+\frac{5x}{12}-2$

$12y=-x^2+5x-24$

PLEASEEE HELP !! in two the three sentences, explain how you would find the line of symmetry for the parabola whose equation is

Arada [10]

Answer:

Axis of symmetry line is parallel to y- axis

Equation of the parabola ( x - ( -2 ))² = (y - 12 )

Step-by-step explanation:

Explanation:-

Given equation is y = x²+4 x+16

y = x²+2 (2 ) x + (2)² - (2)² + 16

y = ( x + 2 )² + 12

( x + 2 )² = y - 12

( x - ( -2 ))² = (y - 12 )

( x- h)² = 4 a ( y - k)

Center (h ,k) = ( -2 , 12)

Here 4 a = 1

a = 1/4

Focus S = ( h , K +a) = ( -2 , 12 + 0.25) = ( -2 , 12.25)

Axis of symmetry line is parallel to y- axis

This is number 8. And I need help.

It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p

Hope this helps! Good luck!

Square pyramid is made up of a base with a side length of 10 inches and faces that are triangles with a height of 12 inches what

Nataly [62]

The surface area of the square pyramid is 360 in²

Explanation:

Given that the side length is 10 inches.

The height of the pyramid is 12 inches.

We need to determine the surface area of the pyramid.

The surface area of the pyramid is given by

$SA=s^2+2sl$

Where s is the side length and l is the slant height.

The slant height can be determined using the formula,

$l=\sqrt{h^2+b^2}$

where h = 12 and $b=\frac{s}{2} =5$

Substituting these values in the formula, we get,

$l=\sqrt{12^2+5^2}$

$=\sqrt{144+25}$

$l=\sqrt{169}$

$l=13$

Thus, the slant height is $l=13$

Now, we shall find the surface area of the pyramid.

Substituting $l=13$ and $s=10$ in the formula $SA=s^2+2sl$ , we get,

$SA=10^2+2(10)(13)$

$=100+260$

$SA=360 \ in^2$

Thus, the surface area of the square pyramid is 360 in²
