Answers

Answer 1

The correct answer is C. 4, 356, 000. You can find this by multiplying 22*22*10*10*10*9.

Answer 2

There are 4,356,000 different passwords are possible.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A phone banking password consists of 2 letters followed by 4 digits.

And, The letters B, I, S, and O are not used, and the last digit cannot be 0.

Hence, We can formulate;

Number of different passwords are possible are,

⇒ 22 × 22 × 10× 10 × 10 × 9.

⇒ 4,356,000

Thus, There are 4,356,000 different passwords are possible.

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. f(x) = 5x + 4 h(x) = x2 + 8x + 24

x = -3
x = 3
x = 4
x = 5

Answers

The exponential function is [tex]f(x)= 5^{x} +4[/tex]
The polynomial function is [tex]h(x)= x^{2} +8x+24[/tex]

We want a value of x as such that [tex]f(x)\ \textgreater \ h(x)[/tex], so

[tex] 5^{x}+4 [/tex] > [tex] x^{2} +8x+24[/tex]

We are provided with four possible value of x. By process of trial and error, we will narrow down two values of x when the statement is changing from false to true

first, we try [tex]x=-3[/tex] by substituting into [tex]f(x)[/tex] and [tex]h(x)[/tex]

[tex] f(-3)=5^{-3}+4 = 4.008 [/tex] and [tex]h(-3)= (-3)^{2}+8(-3)+24=9 [/tex]
so [tex]f(x)[/tex]>[tex]h(x)[/tex] which is not the inequality wanted

We try [tex]x=3[/tex] by substituting into [tex]f(x)[/tex] and [tex]h(x)[/tex]
[tex]f(3)= 5^{3}+4=129 [/tex] and [tex]h(3)= (3)^{2}+8(3)+24=57 [/tex],
so [tex]f(x)[/tex] > [tex]h(x)[/tex] as wanted

We know that any values of [tex]x[/tex] greater than three will give [tex]f(x)[/tex] greater than [tex]h(x)[/tex], so we narrow down to two values that make the statement changes from false to true.

There is one value between -3 and three that makes [tex]f(x)[/tex] greater than [tex]h(x)[/tex]. From here we use the method of trial and error.

We can start with the mid value between -3 and three which is 0
[tex]f(0)= 5^{0}+4=5 [/tex]
[tex]h(0)= 0^{2}+8(0)+24=24 [/tex]
[tex]f(x)[/tex] is less than [tex]h(x)[/tex] which isn't the inequality we want so here we narrow down the value of x must be between 0 and 3

We can try mid-value between 0 and three which is 1.5
[tex]f(1.5)= 5^{1.5}+4=15.18 [/tex]
[tex]h(1.5)= (1.5)^{2}+8(1.5)+24=38.25 [/tex]
[tex]f(x)[/tex] is still less than [tex]h(x)[/tex], so we now narrow down the value of x between 1.5 and 3

We try again using the mid-value between 1.5 and three which is 2.25
[tex]f(2.25)= 5^{2.25}+4=41.38 [/tex]
[tex]h(2.25)= 2.25^{2}+8(2.25)+24=47.0625 [/tex]
We still have [tex]f(x)[/tex] less than [tex]h(x)[/tex] so we can narrow down further the value of x between 2.25 and 3 (which is quite a short interval already)

We can keep trying by choosing a value of x says x=2.6
[tex]f(2.6)= 5^{2.6}+4=69.66 [/tex]
[tex]h(2.6)= 2.6^{2}+8(2.6)+24=51.56 [/tex]
We have [tex]f(x)[/tex] greater then [tex]h(x)[/tex]

The narrowing down process continues where we now have the interval of x between 2.25 and 2.6. Keeping to one decimal place we can find the
value of x=2.4 is the approximate value where [tex]f(x)[/tex] is greater than [tex]h(x)[/tex].

Answer: x=2.4

The correct answer is x = 5.

3 dice of different colors are rolled, and the number coming up on each die is recorded. how many different outcomes are possible?

Answers

Assuming the dice go up to a maximum value of 6. The maximum number of different outcomes is 6^3 (6 times 6 times 6) which would be 216.

Final answer:

When rolling three different dice, the number of possible outcomes can be calculated by performing 6*6*6, which equals 216, as there are 6 possible results on each die.

Explanation:

The question pertains to the count of distinct outcomes when rolling three differently colored dice. Each die has 6 possible outcomes (numbered 1 to 6). Since these are independent events, you multiply the number of outcomes of each event (or the number of outcomes of each die's roll) to get the total number of different outcomes for all the events combined. Hence, the total different outcomes would be 6*6*6 = 216

Hope this helps! :)

Answer:

(Really really really sorry if this incorrect)... ok so it's 17 cm tall in length. That would be 17 blocks high, for example. The area is 102, so 102 cm2 divided in half equals 51, so the width would be 51 cm. So the perimeter is 17 + 17 + 51 + 51 = 136 cm.

First find the slope. m=(y2-y1)/(x2-x1)

m=(4225-1990)/(5-2)=745,

m is the slope, this represents the amount of money earned each month that the business operates.

so far we have:

Find the equation of the parabola whose vertex is the origin and whose directrix is x=-4

Answers

Answer:

Step-by-step explanation:

2020 2021

Equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.

What is Parabola?

A parabola is a curve where any point is at an equal distance from: a fixed point (the focus ), and; a fixed straight line (the directrix )

As we have vertex at the origin i.e. (0,0) and directrix is x=-4 and a line parallel to y-axis,

it must have a focus at (4,0)

Equation of the parabola represents locus of a point (x, y), which moves so that its distance from x=-4 to (4,0) are equal.

Hence, equation of parabola is

(x-4)²+(y-0)²=(x+4)²

(x-4)²+y²=(x+4)²

x²+16-8x=x²+16+8x

-16x=0

x=0

Hence, equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.

Solve 2 cos theta + 2 = 3 in the interval from 0 to 2pi. Round to the nearest hundredth.

Answers

2cos theta = 1 -> cos theta = 1/2

Then theta = pi/3 + 2npi or -pi/3 + 2npi, where n is random interger

And the domain is restricted in [0,2pi]

So answer will be pi/3 or 5pi/3

Final answer:

The solutions to the equation 2 cos θ + 2 = 3 in the interval from 0 to 2π are θ = π/3 and θ = 5π/3, which approximate to 60 degrees and 300 degrees.

Explanation:

The equation given is 2 cos θ + 2 = 3. To solve this equation, first subtract 2 from both sides to get 2 cos θ = 1. Then, divide both sides of the equation by 2 to isolate cos θ, yielding cos θ = 0.5.

In the interval from 0 to 2π (0 to 360 degrees), cos θ = 0.5 occurs at θ = π/3 and θ = 5π/3 (60 degrees and 300 degrees), as these are the angles in the first and fourth quadrants where the cosine value is positive and equal to 0.5.

Therefore, the solutions to the equation are θ = π/3 (θ ≈ 1.05 radians) and θ = 5π/3 (θ ≈ 5.24 radians), or θ ≈ 60 degrees (θ ≈ 1.05) and θ ≈ 300 degrees (θ ≈ 5.24) when rounded to the nearest hundredth of a radian.
