Bill wanted to try out different water craft he went 62 mikes downstream in a motor boat and 27 mikes down stream on a jest ski

valina [46]

Answer:

The speed on motorboat is 20 mph

Step-by-step explanation:

here, we want to find the speed on the motorboat

if he has a speed of x mph on the motor boat, his speed on the ski will be (x + 10) mph

The total hours is 4 hours

Mathematically; speed = distance/time

Time on ski is 27/x+ 10

Time on motor boat is 62/x

The addition of both is 4

Thus;

27/(x + 10) + 62/x = 4

27(x) + 62(x + 10) = 4(x)(x + 10)

27x + 62x + 620 = 4(x^2 + 10x)

89x + 620 = 4x^2 + 40x

4x^2 -49x-620 = 0

using the quadratic formula;

{-b ± √(b^2-4ac)}/2a

where a = 4, b = -49 and c = -620

= 49 ± √(-49)^2-4(4)(-620)/8

So we have

49+ 111/8 or 49-111/8

Speed cannot be negative

(49 + 111)/8

= 20 mph

What is the inverse of f(x)=2^x

GuDViN [60]

Answer:

Step-by-step explanation:

$f(x)=2^x$

$y = {2}^{x}$

$x = {2}^{y}$

${2}^{y} = x$

$ln( {2}^{y} )=ln(x)$

$yln(2)=ln(x)$

<h3> $\frac{yln(2)}{ln(2)} = \frac{ln(x)}{ln(2)}$ </h3><h3> $y = \frac{ln(x)}{ln(2)}$ </h3><h3> ${f}^{ - 1} (x) = \frac{ln(x)}{ln(2)}$ </h3><h3>Hope it is helpful...</h3>

Can someone please do this for me?

san4es73 [151]

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

$\frac{3}{2}$ x = 174

x = 116

x + (x/2 + 6) = 180

x/2 + 6

(116)/2 + 6

<em>To check:</em>

116 + 64 = 180 ✓
