There are many different paths to take but here is my take

15%:22.5%:48%: 74 3/4 Turn everything into a percent
15%:22.5%:48%: 7475% Turn into a decimal
.15: .22: .48: 74.75 Times by 100
15: 22 : 48: 7475 Covert into factors
5(3) : 2(11) : 3(2⁴): 5²(299) Relize there is no common factor...
15: 22 : 48: 7475 <------- Whole numbers

15: 22.5: 48: 74 4/3
= 30: 45: 76: 179 1/2
= 60: 90: 152: 359

For the function f(x) = 2x+2, what is the new function and reflection for-f(x)?

OlgaM077 [116]

Answer:

Step-by-step explanation:

for inverse of f(x)=2x+2

x=2y+2

x-2=2y

(x-2)/2=y

therefore the inverse f(x)=(x-2)/2

Can a line be collinear

LenKa [72]

We can have two or more points lying on the same line collinear.

So we can say points lying on same line are collinear but a line cannot be collinear.

John made this model to show \frac{4}{7}\times\frac{13}{9} 7 4 × 9 13 Using John's model, what is \frac{4}{7}\times\frac{13}

harkovskaia [24]

Answer:

$\frac{4}{7}\times\frac{13}{9} = \frac{52}{63}$

Step-by-step explanation:

Given

See attachment for model

Required

Determine $\frac{4}{7}\times\frac{13}{9}$ from the model

The model is represented by:

$\frac{4}{7}\times\frac{13}{9} = \frac{4}{7}\times\frac{9}{9} + \frac{4}{7}\times\frac{4}{9}$

To get: $\frac{4}{7}\times\frac{9}{9}$ , we consider the first partition

The number of shaded box is 63 ---- this represents the denominator

The total boxes shaded at the bottom is 36 ---- this represents the numerator

So, we have:

$\frac{4}{7}\times\frac{9}{9} = \frac{36}{63}$

To get: $\frac{4}{7}\times\frac{9}{9}$ , we consider the first partition

The number of shaded box is 63 ---- this represents the denominator

The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator

So, we have:

$\frac{4}{7}\times\frac{4}{9} =\frac{16}{63}$

The equation becomes:

$\frac{4}{7}\times\frac{13}{9} = \frac{4}{7}\times\frac{9}{9} + \frac{4}{7}\times\frac{4}{9}$

$\frac{4}{7}\times\frac{13}{9} = \frac{36}{63} + \frac{16}{63}$

$\frac{4}{7}\times\frac{13}{9} = \frac{36+16}{63}$

$\frac{4}{7}\times\frac{13}{9} = \frac{52}{63}$

Given points (r1, u1 ) and (r2, u2) in polar coordinates, obtain a general formula for the distance between them. Simplify it as

sertanlavr [38]

Answer:

$d=\sqrt{r_1^2+r_2^2-2r_1r_2\cos(u_2-u_1)}$

Step-by-step explanation:

The Law of Cosines gives an immediate result. No translation to Cartesian coordinates is necessary. That law makes use of the angle between the vectors, u2-u1

$d^2=r_1^2+r_2^2-2r_1r_2\cos(u_2-u_1)\\\\\boxed{d=\sqrt{r_1^2+r_2^2-2r_1r_2\cos(u_2-u_1)}}$
