Answer:

you literally just translate each shape by the number of squares specified.

Step-by-step explanation:

for example, move shape 1 5 squares to the right, then 4 down. it will be in the middle area of quadrant 1 (where it already is).

Answer:

98.88 ft^2 to nearest hundredth

Step-by-step explanation:

Area of slice = (37/360) * pi * 17.5^2 ( 17.5 = radius ( half diameter of 35))

= 98.88 ft^2

Write a quadratic function in vertex form for the function whose graph has it's vertex at (5,4) and passes through the point (7,

Ivenika [448]

y = - $\frac{3}{4}$ (x - 5)² + 4

the equation of a quadratic in standard form is

y = a(x - h)² + k ( where (h , k ) are the coordinates of the vertex and a is a multiplier )

given vertex = ( 5, 4 ) then

y = a(x - 5)² + 4 ( to find a substitute (7 , 1 ) into the equation )

1= 4a + 4

4a = - 3 ⇒ a = - $\frac{3}{4}$

y = - $\frac{3}{4}$ (x - 5)² + 4 ← ( in vertex form )

marvin has a chain that is 3 5/12 feet long . he uses 2 1/3 feet of the chain , how much chain is left

My name is Ann [436]

In order to calculate left chain, you need to subtract that as follows:
Left chain = 3 5/12 - 2 1/3
L.C. = 41/12 - 7/3
L.C.= 41-28 / 12
L.C. = 13/12

In short, Your Answer would be 13/12 feet or 1 1/12 feet

Hope this helps!

How large a sample must be drawn to estimate population proportion confidence interval width to within .04, with 95% confidence,

lubasha [3.4K]

Answer:

Sample size 'n' = 384

Step-by-step explanation:

Explanation:-

Given margin of error = 0.04

The sample proportion 'p'= 0.80

The margin of error is determined by

$M.E = \frac{Z_{\alpha } \sqrt{p(1-p)} }{\sqrt{n} }$

$0.04 = \frac{1.96 \sqrt{0.80(1-0.80)} }{\sqrt{n} }$

Cross multiplication, we get

$\sqrt{n} = \frac{1.96 \sqrt{0.80(1-0.80)} }{0.04 }$

√n = 19.6

Squaring on both sides , we get

n = 384.16≅384

(x-4)/5=9-(2x-41)/9

jok3333 [9.3K]

For this question, you have to take Least Common Multiplier for which in this case will be "45" as, the denominators can get similar and get multiplied by a same value to form a similar expression. This allows us to cancel out them by common factors. Full process shown below.

$\mathbf{Given \: \: Expression: \: \dfrac{x - 4}{5} = 9 - \dfrac{2x - 41}{9}}$

$\mathbf{\dfrac{x - 4}{5} \times 45 = 9 \times 45 - \dfrac{2x - 41}{9} \times 45}$

$\mathbf{9(x - 4) = 405 - 5 (2x - 41)}$

$\mathbf{9x - 36 = 405 - 10x + 205}$

$\mathbf{9x - 36 = - 10x + 610}$

$\mathbf{9x - 36 + 36 = - 10x + 610 + 36}$

$\mathbf{9x = - 10x + 646}$

$\mathbf{9x + 10x = - 10x + 646 + 10x}$

$\mathbf{19x = 646}$

$\mathbf{\dfrac{19x}{19} = \dfrac{646}{19}}$

$\mathbf{\therefore \quad x = 34}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is; \: \: x = 34}}}$

Hope it helps.
