Answer:

45/51

Step-by-step explanation:

SOH CAH TOA

Sin x = Opposite/hyp

Cos x = Adjacent/hyp

Tan x = Opposite/Adjac

Here we're looking for Sin R, so we want to find opposite side over the hypotenuse.

Thus, $sin R = \frac{45}{51}$

Suppose it takes 4 hours for a certain strain of bacteria to reproduce by dividing in half. If 70 bacteria are present to begin

Sauron [17]

Answer:

1 day: 4480

2 days: 8960

3 days: 13440

$f^{-1}(x) = \sqrt{\frac{x -4}{4}}$ ---- function inverse

Step-by-step explanation:

Given

$f(x) = 70 \cdot 64x$

Solving (a): The amount present after 1 day.

Here, $x =1$

So:

$f(1) = 70 \cdot 64*1= 4480$

Solving (b): The amount present after 2 days.

Here, $x =2$

So:

$f(2) = 70 \cdot 64*2= 8960$

Solving (c): The amount present after 3 days.

Here, $x = 3$

So:

$f(3) = 70 \cdot 64*2= 13440$

Solving (d): The inverse function of:

$f(x)= 4x^2 + 4$

Replace f(x) with y

$y= 4x^2 + 4$

Swap x and y

$x= 4y^2 + 4$

Rewrite as:

$4y^2 = x -4$

Divide by 4

$y^2 = \frac{x -4}{4}$

Take square roots

$y = \sqrt{\frac{x -4}{4}}$

Replace y with function inverse

$f^{-1}(x) = \sqrt{\frac{x -4}{4}}$

jamie is n years old. brian is twice as old as jamie. in 8 yrs, morgan will be 2 yrs more than half of brian and jamies combined

Dimas [21]

Jamie's age is n. (given)

Brian's age is 2n. (given)

Half of Brian and Jamie's present age is (n +2n)/2 = 3n/2.

Let m represent Morgan's age now. Then

... m + 8 = 2 + 3n/2 . . . . . in 8 years, Morgan's age will be 2 more than ...

Subtract 8 to find Morgan's present age:

... m = 3n/2 - 6 . . . . Morgan's present age

Can somebody please help me with this question. Giving lots of points.

Brut [27]

Answer:

x-multiple choice

y- short response

23x+10y=86

28x+5y=76 /×(-2)

23x+10y=86

-56x-10y=-152

-33x=-66

x=2

10y=86-46

10y=40

y=4

multiple choice=2 points

short responce =4points
