The value of sec(θ) given [tex]\tan^2(\theta) = \frac{3}{8}[/tex] is [tex]\frac{\sqrt{22}}{4}[/tex]. Using the identity [tex]\tan^2(\theta) + 1 = \sec^2(\theta)[/tex], we find [tex]\sec(\theta) = \frac{\sqrt{22}}{4}[/tex].

To find the value of sec(θ) given that [tex]\tan^2(\theta) = \frac{3}{8}[/tex], we'll use the trigonometric identity:

[tex]\[ \tan^2(\theta) + 1 = \sec^2(\theta) \][/tex]

Given that [tex]\(\tan^2(\theta) = \frac{3}{8}\)[/tex], we can plug this into the identity:

[tex]\[ \frac{3}{8} + 1 = \sec^2(\theta) \][/tex]

[tex]\[ \frac{3}{8} + \frac{8}{8} = \sec^2(\theta) \][/tex]

[tex]\[ \frac{11}{8} = \sec^2(\theta) \][/tex]

To find [tex]\(\sec(\theta)\)[/tex], we take the square root of both sides, but since sec(θ) is always positive, we'll take the positive square root:

[tex]\[ \sec(\theta) = \sqrt{\frac{11}{8}} \][/tex]

[tex]\[ \sec(\theta) = \sqrt{\frac{11}{8}} \times \frac{\sqrt{8}}{\sqrt{8}} \][/tex]

[tex]\[ \sec(\theta) = \sqrt{\frac{88}{64}} \][/tex]

[tex]\[ \sec(\theta) = \frac{\sqrt{88}}{\sqrt{64}} \][/tex]

[tex]\[ \sec(\theta) = \frac{\sqrt{88}}{8} \][/tex]

[tex]\[ \sec(\theta) = \frac{2\sqrt{22}}{8} \][/tex]

[tex]\[ \sec(\theta) = \frac{\sqrt{22}}{4} \][/tex]

So, the value of [tex]\(\sec(\theta)\)[/tex] given [tex]\(\tan^2(\theta) = \frac{3}{8}\)[/tex]is [tex]\(\frac{\sqrt{22}}{4}\)[/tex].

Complete Question:

Given that tan²(θ) = 3/8, what is the value of sec(θ)?

The value of sec(θ) given that tan²(θ) = 3/8 is (1/4)√22.

To find the value of sec(θ) given that tan²(θ) = 3/8, we first need to recall the relationship between tangent (tan) and secant (sec) functions.

The relationship is as follows:

[tex]\[ \tan^2(\theta) + 1 = \sec^2(\theta) \][/tex]

Given that [tex]\( \tan^2(\theta) = \frac{3}{8} \),[/tex] we can substitute this value into the equation above:

[tex]\[ \left(\frac{3}{8}\right) + 1 = \sec^2(\theta) \][/tex]

Now, let's simplify the expression:

[tex]\[ \frac{3}{8} + 1 = \frac{3}{8} + \frac{8}{8} = \frac{3 + 8}{8} = \frac{11}{8} \][/tex]

So, [tex]\( \sec^2(\theta) = \frac{11}{8} \).[/tex]

Now, to find the value of sec(θ), we take the square root of both sides:

[tex]\[ \sec(\theta) = \sqrt{\frac{11}{8}} \][/tex]

To rationalize the denominator, we multiply both the numerator and the denominator by [tex]\( \sqrt{8} \):[/tex]

[tex]\[ \sec(\theta) = \frac{\sqrt{11 \times 8}}{\sqrt{8 \times 8}} = \frac{\sqrt{88}}{8} \][/tex]

Now, we can simplify the expression under the square root:

[tex]\[ \sqrt{88} = \sqrt{4 \times 22} = 2 \sqrt{22} \][/tex]

So, the final expression for sec(θ) is:

[tex]\[ \sec(\theta) = \frac{2 \sqrt{22}}{8} \][/tex]

And if we simplify it further, we get:

[tex]\[ \sec(\theta) = \frac{\sqrt{22}}{4} \][/tex]

This is the final answer for the value of sec(θ) in terms of the given information.

The Complete Question:

Given that tan²(θ) = 3/8, what is the value of sec(θ)?

Answer: 9/11

Step-by-step explanation: (8,0) (-3, 9). Subtract x values, subtract y values. This is known as delta x and delta y. Slope is rise/run. When you subtract the two points, you are finding the different between them. You're able to plug these x values and y values into an equation and get the correct answer. If you substitute x in, you get y. If you substitute y in, you get x (if you simplify it to get x on one side). So, the change is y is on the top, and change in x is on the bottom. 9 is divided by 11. This is the slope. You can plot this point by rising 9 and running (x axis) 11.

Answer:

440

Step-by-step explanation:

3 hundreds = 300

13 tens= 13 times 10=130

10 ones=10

300+ 130+ 10=

440

The number 440 as  per the statement 3 hundreds (300), 13 tens (130), and 10 ones = 10. Putting them together gives you 440.

Let's analyze the statement to find the number

3 hundreds, 13 tens, and 10 ones.

3 hundreds: This means you have three sets of one hundred. Each hundred is represented as 100. So, 3 hundreds would be

3 × 100 = 300.

13 tens: You have thirteen sets of ten. Each ten is represented as 10.

So, 13 tens would be 13 × 10 = 130.

10 ones: You have ten individual ones.

Now, let's add up all these components:

300 (for the hundreds) + 130 (for the tens) + 10 (for the ones) = 440

Therefore, the number describing in the statement is 440.

Final answer:

The equation for which x = 1 is not a solution is x/3 = 3, as substituting x with 1 gives 1/3, which is not equal to 3.

Explanation:

To determine which equation x = 1 would not be a solution for, we need to substitute x with 1 in each equation and see if it holds true:

x/1 = 1: Substituting x with 1 gives us 1/1 = 1, which is true. Therefore, x = 1 is a solution.

x/2 = 2/4: Substituting x with 1 gives us 1/2 = 2/4, which simplifies to 1/2 = 1/2, also true. Hence, x = 1 is a solution.

x/3 = 3: Substituting x with 1 gives us 1/3 = 3, which is false, because 1/3 is not equal to 3. Therefore, x = 1 is not a solution here.

x/4 = 1/4: Substituting x with 1 gives us 1/4 = 1/4, which is true. Thus, x = 1 is a solution.

The equation for which x = 1 is not a solution is x/3 = 3.

Answer:

A pound is a measure of weight and a cup is a measure of volume.

Step-by-step explanation:

You can't directly compare 1.07 pounds of sugar to 1.23 cups of sugar because they're measured in different units -- weight and volume -- and without a conversion factor (like density), they're not directly comparable. The solution is to convert one measurement to the other, such as by knowing that one cup of granulated sugar typically weighs about 0.44 pounds.

The reason you can't directly compare 1.07 pounds of sugar to 1.23 cups of sugar is because they're measured in two different units -- weight and volume, respectively. Without a known conversion factor (in this case, the density of sugar), you can't equate the two. It's like comparing apples to oranges, the two quantities just aren't compatible without some more information.

Let's consider a real-world example. Just like you can't compare how heavy an object is to how much space it takes up without knowing the material's density, the same goes for comparing sugar in pounds and cups.

The solution is to convert one measurement to the other. For instance, by knowing that one cup of granulated sugar typically weighs about 200 grams (or 0.44 pounds), you could convert your weights and volumes to make a meaningful comparison.

Answer:

y

Step-by-step explanation:

Answer:

(4, 0 ) and (0, - 10 )

Step-by-step explanation:

To find the x- intercept let y = 0 in the equation

5x - 0 = 20

5x = 20 ( divide both sides by 5 )

x = 4 ← x- intercept ⇒ (4, 0 )

To find the y- intercept let x = 0 in the equation

0 - 2y = 20

- 2y = 20 ( divide both sides by - 2 )

y = - 10 ← y- intercept ⇒ (0, - 10 )

The x- and y-intercepts of the equation 5x - 2y = 20 are 4 and -10 respectively. The x-intercept is obtained by setting y = 0, likewise, the y-intercept is obtained by setting x = 0.

The x-intercept and y-intercept of an equation can be found by setting the other variable to zero and solving for the remaining variable. In the equation 5x - 2y = 20:

So, the x-intercept is 4 and the y-intercept is -10 for the given equation.

Step-by-step explanation:

The larger a negative number the less value it actually has, whereas the larger a positive number the more value it has. You can think about it as if someone has taken something from you. If I take $12 from you you have less money than if I were to only take $7 from you. With positive numbers, you would have more money if I gave you 5 dollars than if I only gave you 2 dollars. You will always have more money if I give you money than if I were to take away money, that is why positive numbers are greater than negative numbers.

Answer:

Total cost =$33.47    Tip=$5.58

Step-by-step explanation:

$27.89÷5=5.578     5.578 rounded up to 2 digits=$5.58

$27.89+$5.58=$33.47

total cost is $33.47    tip=$5.58

Lucia should tip $5.58 for a 20% tip on her $27.89 pizza order. The total cost including the tip is $33.47.

To compute the tip Lucia should give for her pizza delivery, we need to calculate 20% of the total cost of the pizzas, which is $27.89. We first convert the percentage into decimal form by dividing 20 by 100, which gives us 0.20. Then we multiply this decimal by the total cost of the pizzas:

Tip =  0.20 imes $27.89 = $5.578

Since we usually round money to the nearest cent, the tip would be approximately $5.58. Now, to find the total cost including the tip, we add the tip to the original total:

Total Cost = Original Cost + Tip

Total Cost = $27.89 + $5.58 = $33.47

Therefore, the total amount Lucia would pay for the pizzas, including a 20% tip, is $33.47.
