how to work out 4.2 × 0.03. Show the working not the answer straight! Show how you got the answer.​

Answers

Answer 1

Answer:

1.26

Step-by-step explanation:

To solve 4.2*0.03, you move the decimal point to the right however many times to both numbers until they are whole numbers.

Doing this, we have 420*3, which took 3 decimal point shifts, so now we do 420*3 to get 1260, and then go 3 decimal places to the left to get the actual answer.

Thus, 4.2*0.03=1.260=1.26

Answers

The table of values of function g(x) and the function f(x) = 5x3 + 2x2 – 6x + 7 are illustrations of exponential functions and polynomial functions

2. The type of function g(x)

The values on the table can be represented as:

(x, g(x)) = (-3, 0.375) (-1, 0.75) (1, 1.5) (3, 3) (5, 6) (7,12) (9, 24)

The above values show that as the values of x increases by 2, the values of function g(x) doubles.

Only an exponential function has this property.

Hence, the table of values represents an (a) exponential function.

3. Example of a polynomial function

A polynomial function is represented as:

y = ax^n  + bx^n-2 + .......... + d

Using the above format, the function that is a polynomial function is (a) f(x) = 5x3 + 2x2 – 6x + 7

4. Key features in the functions

The functions are given as

f(x) = 2x2 + 7x + 6

g(x) = 2x + 5

Set x to 0 to calculate the y-intercept

f(0) = 2(0)2 + 7(0) + 6 = 6

g(x) = 2^0 + 5 = 6

Hence, both functions have the same (c) y-intercept

Rachel had a total of 854 local and foreign stamps. 3/7 of the stamps were foreign stamps. After her father gave her more foreign stamps, the fraction of the stamps that were foreign stamps became 2/3. How many foreign stamps did Rachel’s father give her?

Answers

Answer:

27 other stamps

Step-by-step explanation:

if you take the 88 percent and turn it into a decimal you get .88 Than you multiply .88 times the 225 stamps and that gives you 198 stamps. But that is not the answer because that is the number for foreign stamps and its asking how many other stamps are there. so you would do 225-198 stamps and get the left over 27 stamps!

Step-by-step explanation:

The slope of the line = (y2-y1)/(x2-x1)

= -1/27

Using the point slope form of a straight line:

y - 2 = -1/27(x- (-2))

y - 2 = -1/27x - 2/27

y = -1/27x  - 2/27 + 54/27

y = -1/27x + 52/27

Juan has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $265.36.
He buys 2 bicycle reflectors for $13.61 each and a pair of bike gloves for $37.11.
He plans to spend some or all of the money he has left to buy new biking outfits for $54.87 each.

What is the greatest number of outfits Juan can buy with the money that's left over?

Answers

Answer:

Juan can buy 6 outfits with the money that's left over.

Step-by-step explanation:

Take $640-$265.36-$13.61-$37.11 and then divide

the answer, $332.92 by $54.87.

Juan spent a total of $316.08 on the bicycle, reflectors, and gloves. With the remaining $323.92, he can buy a maximum of 6 biking outfits priced at $54.87 each.

Given that,

Juan has $640 to spend at a bicycle store for new gear and biking outfits.

He buys a new bicycle for $265.36.

He buys 2 bicycle reflectors for $13.61 each.

He buys a pair of bike gloves for $37.11.

To determine the greatest number of outfits Juan can buy with the money he has left,

Calculate the remaining amount after purchasing the bicycle, reflectors, and gloves.

Juan's initial budget is $640.

After buying the bicycle for $265.36, the remaining amount is,

$640 - $265.36 = $374.64.

Next, he buys 2 bicycle reflectors for $13.61 each, which is a total of

2 x $13.61 = $27.22.

Subtracting this amount from the remaining budget, we have

$374.64 - $27.22 = $347.42.

Additionally, he purchases a pair of bike gloves for $37.11, leaving him with $347.42 - $37.11 = $310.31.

Finally, dividing the remaining budget by the cost of each biking outfit, which is $54.87,

Then Juan can buy a maximum of $310.31 / $54.87 ≈ 6 outfits.

Therefore, the greatest number of biking outfits Juan can buy with the money left over is 6.

Which functions have a horizontal asymptote? y = f(x) y = h(x) y = g(x) y = k(x)

Answers

Each function out of the given 4 functions has a horizontal asymptote.

What is an asymptote?

An asymptote is a straight line that continually approaches a given curve but does not meet it at any finite distance.

Mathematically, if y=k is a horizontal asymptote for a function x=f(y) the limiting value of the function is infinity as y→k.

Out of the given curves, for every curve limiting value of the function tends to infinity as y→0

So, each function out of the given 4 functions has a horizontal asymptote.

Therefore, each function out of the given 4 functions has a horizontal asymptote.

Right Riemann sum based on trapezoids offer a compact method that combines upper and lower sums, which is defined below:

Then the probability of a sample being chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 will be 0.1632.

What is a normal distribution?

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The proportions of multiple samples of registered voters who vote are normally distributed, with a mean proportion of 0.38 and a standard deviation of 0.0485.

The z-score is given as

[tex]z = \dfrac{x - \mu}{\sigma}[/tex]

Then the probability of a sample is chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 will be

For x = 0.37, then we have

[tex]z = \dfrac{0.37 - 0.38}{0.0485} \approx -0.206[/tex]

For x = 0.39, then we have

[tex]z = \dfrac{0.39- 0.38}{0.0485} \approx 0.206[/tex]

Then the probability will be

[tex]\rm P(0.37 < x < 0.39) = P(-0.206 < z < 0.206)\\\\ P(0.37 < x < 0.39) =0.58160 - 0.41839 \\\\P(0.37 < x < 0.39) =0.1632[/tex]
