Angle is in standard position and (-5, -7) is a point on the terminal side of 0.
What is the exact value of sec 0 in simplest form with a rational denominator?

Answers

Answer 1

Answer:

Step-by-step explanation:

Don't use 0 as a substitute for θ.  0 is always 0.

cosθ = -5/(2√15)

secθ = 1/cosθ = -2√15/5

Answer 2

The exact value of sec θ is -8.6/5.

What is Trigonometry?

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Point(-5, -7).

Here, x= -5 and y= -7

So, r = √x² + y²

r= √(-5)²  + (-7)²

r= √25 + 49

r = √74

r= 8.6

So, sec θ= H/ B

              = r/x

              = 8.6/ (-5)

              = -8.6/ 5

Eli is following this recipe to bake bread rolls. He uses 600ml of water. How much of the others ingredients does he use? 600g flour 9g salt 12g yeast 30ml oil 500ml water

Answers

Answer:

720 grams of flour.

10.8 grams of salt.

14.4 grams of yeast

36 ml of oil.

Step-by-step explanation:

The recipe is:

600g flour

9g salt

12g yeast

30ml oil

500ml water

Now we use 600ml of water.

We can take the quotient between the amount of water we use and the amount of water in the recipe, this is:

600ml/500ml = 1.2

Then the ratio between the quantities we need to use and the quantities un the recipe should be always 1.2

Or the quantities that Eli needs to use will be 1.2 times the ones shown in the recipe.

Then she needs to use:

1.2*600g flour = 720 grams of flour.

1.2*9g salt = 10.8 grams of salt.

1.2*12g yeast = 14.4 grams of yeast

1.2*30ml oil = 36 ml of oil.

Belvedere goes to the store and buys a soccer ball for $50. The store
is running a discount of 10%. What is the price of the soccer ball after
the discount?

Answers

Answer:

$45 after the discount

Step-by-step explanation:

Set up a proportion.

     [tex]\frac{x}{50} = \frac{10}{100}[/tex]      $50 is the total amount and make the 10% a decimal

x(100) = 50(10)

100 = 500

100 ÷ 500

x = 5     <-- We have to subtract this amount from the total

$50 - $5 = $45 <-- total after the discount

How many squares would have to be shaded so that 2/9 of the shape is shaded?​

Answers

Answer:

4.

Step-by-step explanation:

There are 18 squares, if you want to shade 2/9 you have to make the denominator, which is 9 into 18, so you multiply by 2, you will do the same thing to the numerator, 2x2=4 9x2=18.

Brainiest would be appreciated.

There are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have to determine the number of squares that would have to be shaded so that 2/9 of the shape is shaded

According to the given figure,

There are 3 rows and 6 columns of squares

So the number of squares would be 3 × 6 = 18

There are 18 squares, therefore if you want to shade 2/9, you must first divide the denominator, which is 9 into 18, by 2, and then multiply by 2.

If 2/9 of the shape is shaded: 18 × 2/9 ⇒ 36/9 = 4

Hence, there are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

One year, the population of a city was 354,000. Several years later it was 407,100. Find the percent increase.

Answers

Answer:

15%

Step-by-step explanation:

GIven data

Initial population=  354,000

Final population=407,100

%Error= Final- Initial/initia*100

%Error= 407,100- 354,000/ 354,000*100

%Error= 53100/ 354,000*100

%Error=0.15*100

Hence the error is 15%

Maggie is trying to find the best deal to buy bags of potato chips. Option A: $0.90 for 9 bags of chips Option B: $0.84 for 7 bags of chips Option C: $1.50 for 5 bags of chips Which option is the better deal?
A
Option A
B
Option B
C
Option C

Answers

Answer:

The answer is option A. Since you would be paying 0.10 for each bag.

The solution is Option A.

The best deal for Maggie to buy the bag of potato chips would be 9 bags for $ 0.90 because each bag cost $ 0.10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of each bag be represented as A

Now , the equation will be

a)

$0.90 for 9 bags of chips

The cost of 9 bags = $ 0.90

The cost of 1 bag A = The cost of 9 bags / 9

Substituting the values in the equation , we get

The cost of 1 bag A = 0.90 / 9

On simplifying the equation , we get

The cost of 1 bag A = $ 0.10

b)

$0.84 for 7 bags of chips

The cost of 7 bags = $ 0.84

The cost of 1 bag A = The cost of 7 bags / 7

Substituting the values in the equation , we get

The cost of 1 bag A = 0.84 / 7

On simplifying the equation , we get

The cost of 1 bag A = $ 0.12

c)

$1.50 for 5 bags of chips

The cost of 5 bags = $ 1.50

The cost of 1 bag A = The cost of 5 bags / 5

Substituting the values in the equation , we get

The cost of 1 bag A = 1.50 / 5

On simplifying the equation , we get

The cost of 1 bag A = $ 0.30

Therefore , the 0.10 < 0.12 < 0.30

Hence , the cost of $0.90 for 9 bags of chips is the best deal

Step-by-step explanation:

The given set of numbers (in any order) is:

[tex]\pi, \;\sqrt{10}, \; 3.14, \; \dfrac{22}{7}[/tex]

Convert each number to its decimal equivalent to 4 decimal places:

[tex]\implies \pi=3.1416\;(\sf 4\;d.p.)[/tex]

[tex]\implies \sqrt{10}=3.1623\;(\sf 4\;d.p.)[/tex]

[tex]\implies 3.14 = 3.1400\;(\sf 4\;d.p.)[/tex]

[tex]\implies \dfrac{22}{7}=3.1429\;(\sf 4\;d.p.)[/tex]

Each number has 3 units and 1 tenth.

Comparing the hundredths, all the numbers have 4 hundredths except √10 which has 6 hundredths.  Therefore, √10 is the largest number since 6 > 4.

Comparing the thousandths of the other three numbers, 3.14 is the smallest number as it has zero thousandths.

π is the next smallest as it has a one thousandth.

Therefore, the given set of numbers in increasing order is:

Output equals input times 4 is the function rule from the values in the table.

Looking at the values in the table, we can identify the function rule by analyzing the relationship between the input and output values.

The output values are obtained by applying specific operations to the input values.

Let's examine each statement and see which one matches the given input-output pairs:

Output equals input times -4:

When we multiply the input values by -4, we get the following output values:

[tex]-2 \times -4 = 8[/tex]

[tex]0 \times -4 = 0[/tex]

[tex]1 \times -4 = -4[/tex]

[tex]3 \times -4 = -12[/tex]

This function rule matches the given input-output pairs.

Therefore, the function rule that matches the values in the table is "Output equals input times -4."
