Answers

Answer:

There is a 55% increase in the number of games.

Step-by-step explanation:

Step 1: Calculate the change (subtract old value from the new value)

Step 2: Divide that change by the old value (you will get a decimal number)

Step 3: Convert that to a percentage (by multiplying by 100 and adding a % sign)

Answer:

20=100%

The height of the Statue of Liberty is 305 feet. Nicole, who is standing next to the statue, casts a 6-foot shadow. She is 5 feet tall. How long should the shadow of the statue be?

Answers

Answer:

Create a proportion.

[tex]\frac{5}{6} = \frac{305}{x}\\[/tex]

This proportion is saying,

"If 5 corresponds to 6, then 305 corresponds to what?"

Cross multiply.

5x = 305(6)

5x = 1830

x = 1830 / 5

x = 366

So, the shadow of the statue should be 366 feet.

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{m \angle \: abc \: = 35 \degree}}}}[/tex]

Option C is the best choice.

Step-by-step explanation:

First , Let's know about Corresponding angles :

A pair of interior and exterior angles which lies to the same side of a transversal.Remember that the corresponding angles are always equal.The easiest way to think of corresponding angles is the 'F - Pattern'.

✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.

[tex] \sf{x = 3x - 70\: ( \: being \: corresponding \: angles})[/tex]

[tex] \longrightarrow{ \sf{x - 3x = - 70}}[/tex] { Move 3x to left hand side and change it's sign )

[tex] \longrightarrow{ \sf{ - 2x = - 70}}[/tex] { Combine like terms }

[tex] \longrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ - 70}{ - 2} }}[/tex] { Divide both sides by -2 }

[tex] \longrightarrow{ \sf{x = 35}}[/tex]

The value of x is 35°

Now, As we are asked to find the value of m [tex] \angle[/tex] ABC , replace the value of x :

[tex] \sf{m \angle \: ABC \: = (3x - 70) \degree}[/tex]

[tex] \dashrightarrow{ \sf{(3 \times 35 - 70) \degree}}[/tex]

[tex] \dashrightarrow{ \sf{(105 - 70) \degree}} [/tex]

[tex] \longrightarrow{ \boxed{ \sf{35 \degree}}}[/tex]

Therefore , m [tex] \angle[/tex] ABC = 35°

And we're done !

Hope I helped!

What is the y-intercept of function f?

Answers

Step-by-step explanation:

y-intercept of function f is 1.

What is a function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given function

f(x) = -3x -2 , -∞ < x < -2

     = -x + 1, -2 ≤ x < 3

     = 2x + 5, 3 ≤ x < ∞

For y-intercept, x =0, f(x) = -x + 1                   [∵ -2 < 0 < 3]

f(0) = -0 + 1

= 1

Hence, y-intercept of function f is 1.

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the number of minivans sold each week.

Answers

Answer:

we conclude that an inequality 'c ≥ 5' denotes this situation.

Step-by-step explanation:

Given

A car dealer ship sells at least 5 minivans

When we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.

For instance,

'm≥n' means 'm' is greater than or equal to 'n'.

It means 'm' is at least equal to 'n'.

Coming back to the question,

Let 'c' represent the number of minivans sold each week.

As the car dealer ship sells at least 5 minivans. so the

inequality will be: c ≥ 5

Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.

Explanation:

Inscribed angle ADB subtends the minor arc AB. Inscribed angle ACB subtends the same minor arc AB. The rule is that if two inscribed angles subtend the same arc, then they are the same measure.

We can prove this with the inscribed angle theorem which says

central angle = 2*(inscribed angle)

Let's say point E is the center of the circle. By the inscribed angle theorem, we know that,

angle AEB = 2*(angle ADB)

angle AEB = 2*43

angle AEB = 86

Then we go in reverse of this process to find angle ACB

angle AEB = 2*(angle ACB)

86 = 2*(angle ACB)

2*(angle ACB) = 86

angle ACB = 86/2

angle ACB = 43

So this is how we prove the two inscribed angles are congruent.

Scientists studying biodiversity of amphibians in a rain forest have discovered that the number of species is decreasing by 2% per year. There are currently 74 species of amphibians in the rain forest. Which logarithmic function models the time, , in years, it will take the number of species to decrease to a value of n?

The answer is D.

Step-by-step explanation:

The logarithm function that models the time, f(n) , in years is [tex]\rm f(n) = log_{0.98} (\dfrac{n}{74})[/tex], the correct option is D.

What is an Exponential Function?

An exponential function can be represented in the form f(x) = abˣ.

The number of species is decreasing by 0.02

Current number of species = 74

The time f(n) years is given by

f(n) = 74 (0.98)ⁿ

Converting exponent to logarithm form

x = aⁿ

y = logₓ a

f(n) = 74 (0.98)ⁿ

3 Answers:

A) y intercept is (0,3)

C) Axis of symmetry is x = -1

D) Vertex is (-1, 4)

So basically everything but choice B is true.

========================================

Explanation:

Choice A is true because plugging in x = 0 leads to y = 3. Effectively, anything with an x goes away when x = 0 leaving that 3 behind. So finding the y intercept in this form is fairly fast.

-------------------

To check choices B through D, let's convert the equation into vertex form.

y = -1x^2 - 2x + 3 is in the form y = ax^2 + bx + c where

a = -1

b = -2

c = 3

The vertex is located at (h,k) such that h = -b/(2a)

Plug the values of 'a' and 'b' into the equation below

h = -b/(2a)

h = -(-2)/(2*(-1))

h = 2/(-2)

h = -1

The x coordinate of the vertex is x = -1

Then use this to find the y coordinate of the vertex

y = -1x^2 - 2x + 3

y = -1(-1)^2 - 2(-1) + 3

y = 4

The y coordinate of the vertex is 4, meaning k = 4

The vertex overall is (h,k) = (-1, 4)

This shows choice D is true, meaning choice B has to be false.

Choice C is true because the axis of symmetry is the x coordinate of the vertex. This is the vertical line that cuts the parabola into two mirrored halves. This vertical line always goes through the vertex.
