Answer:
[tex]1.6 \times 10 = 16 \\ [/tex]
To multiply a decimal by 10, move the decimal point in the multiplicant by one place to the right. Here we multiplied the number 1.6 by 10 so we move 1 place to the right.
To multiply a decimal by 100, move the decimal point in the multiplicant by two places to the right.
If f(x) = 2x and g(x) = 5x + 2, what is (f + g)(x) when x = 3?
Answer:
f÷g=2x+5x+2=7x+2
x=3
7×3+2=21+2=23
The value of (f + g)(x) when x = 3, if f(x) = 2x and g(x) = 5x + 2, is 23.
What is function?The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).
Given:
f(x) = 2x and g(x) = 5x + 2
Calculate (f + g)(x) as shown below,
f(x) + g(x) = 2x + 5x +2
f(x) + g(x) = 7x + 2
Put x = 3
f(3) + g(3) = 7 × 3 + 2
f(3) + g(3) = 23

Use the following experiment. A state lottery game consists of choosing one card from each of the four suits in a standard deck of playing cards. (There are 13 cards in each suit.)
Count the number of ways in which four 8's can be chosen.
Answer:
24
Step-by-step explanation:
there are 4 way of choosing an ace card after choosing an ace card now we have 3 ways of choosing a king after choosing a king there are two ways of choosing a queen after choosing queen there is only one way of choosing a jack .
so the number of elements in the event is =4×3×2×1=24
we use permutation here for finding the total number of elements
Using the concept of combination, since the order of selection doesn't matter, the number of ways in which four 8's can be chosen is 1
There are 13 cards in a suit :
Number of cards numbered 8 in a suit = 1
Number of ways of choosing a specific card :
(13C1) ÷ 13 = (13 ÷ 13) = 1 way
Since there are four different suits :
The number of ways of selecting a card numbered 8 from 3 each suit will be 1.
Hence, the number of ways in which four 8's can be chosen would be :
1 × 1 × 1 × 1 = 1Therefore, there is only 1 way of choosing four 8's

For what values of x is f(x) = x a function?
Answer:
All real values of x.
Step-by-step explanation:
f(x) = x passes the line test, as it is a simple line with a slope of 1, so by that reasoning, f(x) = x is always a function.

Answer:
5x +y = 20
Step-by-step explanation:
The equation of the parallel line will have the same x- and y-coefficients. The constant will be adjusted to make the equation true at the given point.
5x +y = 5(3) +(5) = 20
The parallel line is ...

Answer:

Step-by-step explanation:
a) One way you can try to identify the pattern is to look for the differences between the images shown, then divide those differences by 2. For example, the total number of vertical dots is 2, then 4 in patterns 2 and 4. This suggests the total number of vertical dots is equal to the pattern number..
The total number of horizontal dots is 4, then 6 in patterns 2 and 4. This suggests that the number of horizontal dots increases by 1 in each pattern. This would mean pattern 1 would have 3 total horizontal dots and 1 total vertical dot. It will look like one row of 3 dots.
Pattern 3 will have 5 total horizontal dots and 3 total vertical dots. The sequence of patterns will look like the attachment.
__
b) The total number of dots in each pattern is 2×(pattern number) +1. Then the number of dots in Pattern 7 will be 2×7 +1 = 15 dots.
Anyone know how I can solve RL from this equation, because I have been trying and I can't get the result[tex]10=-2,5+\frac{0.02*RL+2,5}{625} (625+500)[/tex]
* this sign is to multiply
expected result is = 222.2
Answer:
steps below
Step-by-step explanation:
10 = -2.5 + ((0.02*RL + 2.5) / 625)*(625+500)
0.02*RL + 2.5 = (10+2.5)*625 / (625+500)
= 12.5*625 / 1125
=6.9444444
RL = (6.9444444 - 2.5) / 0.02
= 4.44444... / 0.02
= 222.22222 ....

A hot air balloon is at an elevation of 1,250 feet. Its elevation begins to change at a rate of -22.5 feet per minute. How many minutes will it take the balloon to descend to an elevation of 935 feet? Use the Distance Formula: d = rt
Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.
Let A and B be two disjoint events such that P(A) = 0.47 and P(B) = 0.3.
What is P(A or B)?
Work Shown:
P(A or B) = P(A) + P(B)
P(A or B) = 0.47 + 0.30
P(A or B) = 0.77
Notes:
The formula only works if A and B are disjoint, aka mutually exclusiveIf A and B are not disjoint, then use this formula: P(A or B) = P(A) + P(B) - P(A and B)Answer:
P(A or B) = 0.77
