Kevin has at most $30 to spend at the fair. The entrance fee is $5.50 and each activity is $1.25.
Write the equation that represents the problem.

Answers

Given:

Entrance fee = $5.50

Additional fee =  $1.25 for each activity.

Total amount spend at fair = $30

To find:

The equation that represents the problem.

Solution:

Let the number of activities be [tex]x[/tex].

Additional fee for 1 activity = [tex]\$1.25[/tex]

Additional fee for x activity = [tex]\$1.25x[/tex]

Total fee = Entrance fee + Additional fee for x activity

               = [tex]\$5.50 + \$1.25x[/tex]

It is given that Kevin has at most $30 to spend at the fair. So, total fee must be equal to $30.

[tex]\$5.50 + \$1.25x=\$30[/tex]

[tex]5.50+1.25x=30[/tex]

Therefore, the require equation is [tex]5.50+1.25x=30[/tex].

Note: The inequality for the given problem is [tex]5.50+1.25x\leq 30[/tex].

Answer: The answer to what is the measure of angle x is 48°.

Step-by-step explanation: It’s because this angle is complementary Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Example: 5° and 85° are complementary angles.

f(x)=-2(x-4)^2+8 find the vertex

Answers

Set the polynomial equal to

y

to find the properties of the parabola.

y = -3(x+4)^2 - 8

Use the vertex form, y = a (x-h)^2 + k, to determine values of a,h and k

a = -2

h = -4

k = -8

Find the vertex (h,k)

As per the vertex form of a quadratic equation, the vertex of the given quadratic equation is (4, 8).

What is a quadratic equation?

"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0)."

What is the vertex form of a quadratic equation?

"The vertex form of a quadratic equation is:

y = a(x - h)² + k

Here, a, h, and k are real numbers, where a ≠ 0. x and y are variables.

Here, (h, k) is the vertex and (x, y) represents a point on the graph of the given equation."

Here, the given quadratic equation is:

y = f(x) = -2(x - 4)² + 8

By comparing it with the vertex form of a quadratic equation, we get:

h = 4, y = 8.

Therefore, the vertex(h, k) of the given quadratic equation is (4, 8).

Find the circumference of the circle. Use 3.14 for the value of ", Round your answer to the nearest tenth.

Answers

The formula for circumference is 2*pi*r
We plug in these values and get 2*pi*2.9
Or 18.2 in

Answer:

18.2 cm

Step-by-step explanation:

Given,

Radius of the circle = 2.9 in.

Therefore,

Circumference of the circle

[tex] = 2\pi r[/tex]

[tex] = 2 \times 3.14 \times 2.9 \: cm[/tex]

= 18.212 cm

As,

It has asked for nearest tenth so it will be,

18.212 cm

Since, there is 1 in the hundredth digit so it will round to 0.

Hence,

18.2 cm is the required circumference of the circle rounded to nearest tenth. (Ans)

The value of logarithm log base 4(2 is 1/2.

What is Logarithm?

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b.

Given:

Rewrite as an equation.

log base 4(2)=x

and, Rewrite log base 4(2)=x in exponential form using the definition of a logarithm. If x and b  are positive real then

log (base b) x= y equivalent to [tex]b^y[/tex] = x

Create expressions in the equation that all have equal bases.

log base 4(2)=x

[tex](2^2)^x[/tex] = 2

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

2x = 1

x= 1/2.
