Answer:

$351 and $5751

Step-by-step explanation:

Given, Justin opened an investment account with $5400. At the end of the year, 6.5% increased. So, the total increase in the dollar is 5400* 0.065 = 351. The increase in the dollar is $364.

At the end of the year, Justin will have 5400 + 351 = $5,751. So, Justin will have $5,751 at the end of the year in his investment bank account.

Answer:

$351

$5,751

Step-by-step explanation:

Justin opened an investment account with $5400.

At the end of the year, the amount in the account had increased by 6.5%.

So,

$5,400 - 100%

$x - 6.5%

Write a proportion:

$\dfrac{5,400}{x}=\dfrac{100}{6.5}$

Cross multiply:

$100x=5,400\cdot 6.5\\ \\x=54\cdot 6.5\\ \\x=\$351$

Justin's increase in dollars is $351.

In his account at the end of the year was

$\$5,400+\$351=\$5,751$

Given tan theta =9, use trigonometric identities to find the exact value of each of the following:_______

Ludmilka [50]

Answer:

$(a)\ \sec^2(\theta) = 82$

$(b)\ \cot(\theta) = \frac{1}{9}$

$(c)\ \cot(\frac{\pi}{2} - \theta) = 9$

$(d)\ \csc^2(\theta) = \frac{82}{81}$

Step-by-step explanation:

Given

$\tan(\theta) = 9$

Required

Solve (a) to (d)

Using tan formula, we have:

$\tan(\theta) = \frac{Opposite}{Adjacent}$

This gives:

$\frac{Opposite}{Adjacent} = 9$

Rewrite as:

$\frac{Opposite}{Adjacent} = \frac{9}{1}$

Using a unit ratio;

$Opposite = 9; Adjacent = 1$

Using Pythagoras theorem, we have:

$Hypotenuse^2 = Opposite^2 + Adjacent^2$

$Hypotenuse^2 = 9^2 + 1^2$

$Hypotenuse^2 = 81 + 1$

$Hypotenuse^2 = 82$

Take square roots of both sides

$Hypotenuse =\sqrt{82}$

So, we have:

$Opposite = 9; Adjacent = 1$

$Hypotenuse =\sqrt{82}$

Solving (a):

$\sec^2(\theta)$

This is calculated as:

$\sec^2(\theta) = (\sec(\theta))^2$

$\sec^2(\theta) = (\frac{1}{\cos(\theta)})^2$

Where:

$\cos(\theta) = \frac{Adjacent}{Hypotenuse}$

$\cos(\theta) = \frac{1}{\sqrt{82}}$

So:

$\sec^2(\theta) = (\frac{1}{\cos(\theta)})^2$

$\sec^2(\theta) = (\frac{1}{\frac{1}{\sqrt{82}}})^2$

$\sec^2(\theta) = (\sqrt{82})^2$

$\sec^2(\theta) = 82$

Solving (b):

$\cot(\theta)$

This is calculated as:

$\cot(\theta) = \frac{1}{\tan(\theta)}$

Where:

$\tan(\theta) = 9$ ---- given

So:

$\cot(\theta) = \frac{1}{\tan(\theta)}$

$\cot(\theta) = \frac{1}{9}$

Solving (c):

$\cot(\frac{\pi}{2} - \theta)$

In trigonometry:

$\cot(\frac{\pi}{2} - \theta) = \tan(\theta)$

Hence:

$\cot(\frac{\pi}{2} - \theta) = 9$

Solving (d):

$\csc^2(\theta)$

This is calculated as:

$\csc^2(\theta) = (\csc(\theta))^2$

$\csc^2(\theta) = (\frac{1}{\sin(\theta)})^2$

Where:

$\sin(\theta) = \frac{Opposite}{Hypotenuse}$

$\sin(\theta) = \frac{9}{\sqrt{82}}$

So:

$\csc^2(\theta) = (\frac{1}{\frac{9}{\sqrt{82}}})^2$

$\csc^2(\theta) = (\frac{\sqrt{82}}{9})^2$

$\csc^2(\theta) = \frac{82}{81}$

A box of pancake mix has `6` cups of mix.

kenny6666 [7]

The fraction of the box of pancake that eliza used is; 1/8.

<h3>What are fractions?</h3>

We are told that the box of pancake mix has 6 cups.

Now, Eliza uses 3/4 of a cup for a recipe.

Since there are 6 cups in the box, it means the fraction of the box of pancake that Eliza used is;

(3/4)/6 = 3/24 = 1/8

In conclusion, the fraction of the box of pancake that eliza used is 1/8.

A 90-day simple interest loan in the amount of $2350 will be paid in full in the amount of $2500 . Find the rate of the loan.

ivolga24 [154]

Answer:

The rate of simple interest is 25.89 %

Step-by-step explanation:

Given as :

The principal = $2350

The Amount = $2500

The time period = 90 days = $\frac{90}{365}$ year = 0.2465 year

Let The rate of interest = R %

So, Interest = Amount - Principal

Or, Interest = $2500 - $2350 = $150

<u>From Simple Interest method </u>

Simple Interest = $\frac{Principal\times rate\times Time}{100}$

Or, $150 = $\frac{$2350\times rate\times 0.2465 }{100}$

or, $150 × 100 = $579.275 × Rate

So, Rate = $\frac{15000}{579.275}$

∴ Rate = 25.89 %

Hence The rate of simple interest is 25.89 % Answer
