6 0

Answer:

It is purple

Step-by-step explanation:

Because you need to not only match the highest record you need to go above the highest record so x has to be greater than 0.09 so that's why purple is basically saying x is greater than 1.57 minus 1.48 which is what she jumped but they're asking how much more does she need to jump to beat the record so you just minus 1.57 by 1.48 which gets you 0.09 but it needs to be greater than that so that's why it's purple

With reference to the figure, sin X equals?<br> 1.) 0.250<br> 2.)0.447<br> 3.)0.894<br> 4.)1

Flura [38]

Answer:

3.) 0.894

Step-by-step explanation:

✔️First, find BD using Pythagorean Theorem:

BD² = BC² - DC²

BC = 17.89

DC = 16

Plug in the values

BD² = 17.89² - 16²

BD² = 64.0521

BD = √64.0521

BD = 8.0 (nearest tenth)

✔️Next, find AD using the right triangle altitude theorem:

BD = √(AD*DC)

Plug in the values into the equation

8 = √(AD*16)

Square both sides

8² = AD*16

64 = AD*16

Divide both sides by 16

4 = AD

AD = 4

✔️Find AB using Pythagorean Theorem:

AB = √(BD² + AD²)

AB = √(8² + 4²)

AB = √(64 + 16)

AB = √(80)

AB = 8.9 (nearest tenth)

✔️Find sin x using trigonometric ratio formula:

Reference angle = x

Opposite side = BD = 8

Hypotenuse = AB = 8.944

Thus:

$sin(x) = \frac{opp}{hyp} = \frac{8}{8.944} = 0.894$ (nearest thousandth)

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms i

Luden [163]

Answer:

Approximately 76.5 mg.

Step-by-step explanation:

Given,

The initial quantity of the Bismuth-210, P = 233 mg,

Also, the rate of decay per day, r = 13 %

Thus, the quantity of the Bismuth-210 after 8 days would be,

$A=P(1-\frac{r}{100})^8$

$=233(1-\frac{13}{100})^8$

$=233(1-0.13)^8$

$=233(0.87)^8$

$=76.4733194697$

$\approx 76.5\text{ mg}$

The cost of manufacturing a printer is $35. The manufaturer has a markup of 15% when selling to a retailer. The retailer has a m

ivolga24 [154]

So basically there is an increase by 15% and 35% of $35.

You find out:
5 % of $ 35 = 1.75
10% of $35 = 3.5
15% of $35 = 5.25

30% of $35 = 10.5
35% of $ 35 = 11.25

5.25 + 11.25 = $16.5

$35 + $16.5 = $51.5

The answer is $51.50

I hope this was helpful and the brainliest answer :p

Find the solution to the system of equations.

yawa3891 [41]

Answer:

x = 1, y = -4

Step-by-step explanation:

set each equation equal:

-7x + 3 = -x - 3

-6x + 3 = -3

-6x = -6

x = 1

y = -7 + 3

y = -4
