Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

take f(x)=5x-6, which is y=5x-6

switch the y for x and x for y and you get

x=5y-6

then add 6 on both sides and you get

x+6=5y

now divide both sides by 5 and you get

y=(x+6)/5

which is the inverse of the original function

Answer:

Solution given:

f(x)=5x-6

let f(x)=y

we get

y=5x-6

Interchanging role of x and y

x=5y-6

x+6=5y

y=[tex]\bold{\frac{x+6}{5}}[/tex]

so

f-¹=[tex]\bold{\frac{x+6}{5}}[/tex]

Answer:

The ratio of senior members to junior members at the company is 1 : 3

Step-by-step explanation:

The given average number of years of experience of the senior employees, x = 16 years

The given average number of years of experience of the junior employees, y = 7 years

Let a represent the number of senior employees in the company, and let b represent the number of junior workers in the company, we have;

(16·a + 4·b)/(a + b) = 7

∴ (16·a + 4·b) = (a + b) × 7 = 7·a + 7·b

16·a - 7·a = 7·b - 4·b

9·a = 3·b

a/b = 3/9 = 1/3

a/b = 1/3

The above equation, expressed as a ratio is, a : b = 1 : 3

Therefore;

The ratio of senior members to junior members at the company, a : b = 1 : 3.

Answer:

Step-by-step explanation:

The vertices lie on the x-axis, as is determined by their coordinates. This makes the center of this hyperbola (0, 0) because the center is directly between the vertices. The fact that the foci also lie on the x-axis tells us that this is the main axis. What this also tells us is which way the hyperbola "opens". This one opens to the left and the right as opposed to up and down. The standard form for this hyperbola is:

[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex] and so far we have that h = 0 and k = 0.

By definition, a is the distance between the center and the vertices. So a = 5, and a-squared is 25. So we're getting there. Now here's the tricky part.

The expressions for the foci are (h-c, k) and (h+c, k). Since we know the foci lie at +/-13, we can use that to solve for c:

If h+c = 13 and h = 0, then

0 + c = 13 and c = 13.

We need that c value to help us find b:

[tex]c^2=a^2+b^2[/tex] and

[tex]13^2=5^2+b^2[/tex] and

[tex]169=25+b^2[/tex] and

[tex]144=b^2[/tex] so

b = 12. Now we're ready to fill in the equation:

[tex]\frac{x^2}{25}-\frac{y^2}{144}=1[/tex] and there you go!

Answer:

Yes, by SSS Similarity Theorem

Step-by-step explanation:

the triangles are similar because the sides are proportional, the common ratio is 1.5.

if you look at the corresponding sides of the triangle and multiply 1.5 to the smaller triangle measurements, you get the bigger triangle's corresponding measurements:

3 * 1.5 = 4

4 * 1.5 = 6

6 * 1.5 = 9

Yes the triangle are similar by SSS Similarity Theorem.

Triangles' similarity can be characterized based on their attributes.

If two triangles are similar,

(I) their respective angles are equal, and

(ii) their corresponding sides have the same proportion (or proportion

We have two triangles.

From the triangle we can write

AB / ED = 4/ 6 = 2/3

and, AC / FD = 6 / 9 = 2/3

and, BC / EF = 3 / 4.5 = 30 /45 = 2/3

Thus, AB / ED = AC / FD = BC / EF = 2/3

By SSS Similarity Criteria triangles are similar.

3.35 hours is 3 hours and 21 minutes.

3.35 hours is also equivalent to 201 minutes and 0 seconds or 12060 seconds.

Hope this helps!

Have a wonderful day!

Answer:

3 hours and 21 minutes

Step-by-step explanation:

Hello!

(x + 3) = 1

x + 3 = 1

x = 1 - 3

x = -2

(2x + 5) = (3n + 2)

[2 × (-2) + 5] = (3n + 2)

(-4 + 5) = (3n + 2)

1 = (3n + 2)

1 = 3n + 2

3n + 2 = 1

3n = 1 - 2

3n = -1

n = -1 : 3

n = -1/3

Answer:

[tex]m<NLM = 30[/tex]

Step-by-step explanation:

1. Approach

The easiest way to solve this problem is to find the degree measure of the parameter (x). Use the fact that line (LN) is a diameter to solve for (x), beacause the angle measure of a circle on either side of the diameter is (180) degrees. One can then find the measure of arc (mNM), and then find the measure of the angle (<NLM) using the inscribed angles theory.

2. Find the measure of (x)

A diameter is the largest chord or segment in a circle. It intersects a circle at two points and runs through the center of a circle. The degree measure of a circle on either side of the diameter is (180) degrees. As per the given image, line (LN) is a diameter. The arcs (mLM) and (mNM) make up half of the circle, or rather one side of the diameter. With this information, one can form an equation and solve for the parameter (x) using this information:

[tex](mLM)+(mNM)=180[/tex]

Substitute,

[tex](mLM)+(mNM)=180[/tex]

[tex](13x-10)+(7x-10)=180[/tex]

Simplify,

[tex](13x-10)+(7x-10)=180[/tex]

[tex]20x-20=180[/tex]

Inverse operations,

[tex]20x-20=180[/tex]

[tex]20x=200[/tex]

[tex]x=10[/tex]

3. Find the measure of angle (<NLM)

The inscribed angles theorem states that an angle with its vertex on the circumference (outer edge) of a circle is equal to half of the surrounding arc. One can form an equation and solve for the measure of angle (<NLM).

[tex]m<NLM=\frac{1}{2}(mNM)[/tex]

Substitute,

[tex]m<NLM=\frac{1}{2}(mNM)[/tex]

[tex]=\frac{1}{2}(7x-10)[/tex]

[tex]=\frac{1}{2}(7(10)-10)\\\\=\frac{1}{2}(70-10)\\\\=\frac{1}{2}(60)\\\\=30[/tex]

≈ 5.51 hours

Equation: 4.25h + 10

The number of hours Amanda rented the bike is 5.5 hours.

The equation used to solve this problem is 33.38 = 10 + 4.25h.

The rent cost for the helmet is $10.

The rent cost for the bike per hour is $4.25.

We need to find the number of hours Amanda rented the bike as she paid $33.38 in total.

We also have to make an equation that would solve this problem.

Consider h = number of hours Amanda rented the bike.

The cost for renting the helmet = $10.

And rent cost for the bike per hour = $4.25.

Amanda's total cost = Helmet rent cost + bike rent cost

Since we do not know the number of hours the bike was rented we will denote bike rent cost  = $4.25 x h

We have,

$33.38 = $10 + $4.25 x h

33.38 = 10 + 4.25 x h

33.38 - 10 = 4.25 x h

23.38 = 4.25 x h

h = 23.38 / 4.25

h = 5.5011

Rounding to the nearest tenths we get,

h = 5.5 hours

The number of hours Amanda rented the bike is 5.5 hours.

The equation used to solve this problem is 33.38 = 10 + 4.25h.

Answer:

1. 144⁰

2. 60⁰

Step-by-step explanation:

The formula to find the measure of the interior angles of a regular polygon is:

m< = (n - 2) • 180/n where n = the number of sides

For a decagon, there are 10 sides.

m< = (10-2) • 180/10 = 144°

A regular polygon/equilateral triangle is defined as having equal sides and angles.

Answer:

given ABCDEFGHIJ is a decagon

As we know the sum of all ten interior angles of a decagon = 1440°

so measure of each angle of decagon = (1440/10)° = 144°

so the measure of ∠A would be 144° (C)

given Δ ABC is a equilateral triangle

As we know the sum of all three interior angles of a equialter traingle = 180°

so if one angle of an equilateral triangle is 60°

then the remaining of the angles would have the measure of 60° each

So answer = 60°(B)

Step-by-step explanation:

When you learn calculus you'll be able to do this by hand (without a calculator) but for now we have to just kind of guess. We know that 8 x 8 = 64 and 9 x 9 = 81, so the number is between 8 and 9. Since 68 is closer to 64 than it is to 81, the number is closer to 8. Like less than 8.5. 8.1 squared is 65.61, (you can do this by hand...without a calculator) and 8.2 squared is 67.24, and 8.3 squared is 68.89. 8.3 squared is too high while 8.1 squared was too low; the estimation to the nearest tenth is 8.2
