Answer:
it is 6x²+ 9x- 15
Step-by-step explanation:
the weather forecast at the probability being cloudy tomorrow is 30%, the probability of the being rainy is 15%., and the probability being both calling and rate is 14%. What's the probability of it being rainy, you know it will be cloudy?
Cloudy = 0.30
Rain = 0.15
Both = 0.14
Probability of Rain if cloudy:
P(Both)/P(Cloudy) = 0.14/0.30 = 14/30 = 0.4666
Multiply by 100:
0.4666 x 100 = 46.67%
Answer is b. About 46.67%
What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(5x)?
Answer:
Step-by-step explanation:
If the parent function is f(x) = x² and the transformed function is g(x) = a(x)²
For a > 1, then the transformed function g(x) will be vertically stretched by a factor of 'a'
For 0 < a < 1, then the transformed function will be vertically compressed or shrink by a factor of 'a'
For a function f(x) = x² when transformed to f(5x) = (5x)²
g(x) = 25x²
Therefore, graph of the parent function f(x) will be vertically stretched by 25 units.
Use the table of values to find the function's values. If x = 0, then f(0) = . If f(x) = 27, then x =
If x = 0, then the value of the function f(0) will be negative 15. And if the value of the function f(x) is 27. Then the value of x will be 3.
What is a function?A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
The table is given below.
If x = 0, then the value of the function f(0) will be
f(0) = -15
And if the value of the function f(x) is 27. Then the value of x will be
x = 3

For their twentieth wedding anniversary, Richard and Sylvia had a party for several of their best friends. Things were going along just fine until one of their friends asked the happy couple who was older! Here's what they had to say. Richard: "I am older than my wife." Sylvia: "I am younger than my husband." That might have been the end of it, but one of the guests knew that at least one member of the couple was lying. Well, who is older, Richard or Sylvia?
Answer:
Richard is older
Step-by-step explanation:
We can set up an inequality for both statements.
Let r equal Richard's age and s equal Sylvia's age.
"I am older than my wife."
Since Richard is speaking, the inequality would look like this:
r > s
This means Richard is older than Sylvia.
"I am younger than my husband."
Since Sylvia is speaking, the inequality would look like this:
s < r
This means that Sylvia is younger than Richard.
We can flip one inequality to "see" them from the same perspective.
Let's use s < r
To make it so that we can see the relationship from Richard's perspective, flip the entire inequality.
s < r
to
r > s
The inequality from the first quote is identical to this one!
Therefore, Richard is older than Sylvia.

The Function f is defined by f(x)=2x+3/x+2
find f(n+3)
Answer:
(2n+9)/( n+5)
Step-by-step explanation:
f(x)=(2x+3)/(x+2)
Let x = n+3
f(n+3)=(2*(n+3)+3)/(n+3+2)
= (2n+6+3)/(n+5)

Identify the 7th term of the given geometric sequence. HELP ASAP!!!
6, 15, 37.5, 93.75,...
Answer:
1464.84375
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 6 and r = 15 ÷ 6 = 2.5, thus
[tex]a_{7}[/tex] = 6 × [tex](2.5)^{6}[/tex] = 6 × 244.140625 = 1464.84375
The seventh term of the geometric progression will be 1464.84375
What is a geometric progression?
When there is a constant between the two successive numbers in the series then it is called a geometric series.
The nth term of a geometric sequence is
[tex]a_n =a_1(r)^{n-1}[/tex]
where a₁ is the first term and r is the common ratio
Here a₁ = 6 and r = 15 ÷ 6 = 2.5, thus
[tex]a_7=6\times (2.5)^{6}[/tex] = 6 × 244.140625 = 1464.84375
Therefore the seventh term of the geometric progression will be 1464.84375

A softball is thrown from the top of a 30ft building. The height of the ball is modeled by
h(t) = -16ť? + 20+ + 30
where t is time in seconds.
How long does it take for the ball to hit the ground?
Question to answer: How long does it take for the ball to hit the ground? Round to the nearest tenth.
The ball hits the ground at
seconds.
Answer:
2 seconds
Step-by-step explanation:
When the ball hits the ground, its height (h) will be 0. You can therefore set up the following equation:
[tex]0=-16t^2+20t+30 \\\\-4(4t^2-5t-6)=0[/tex]
Factor:
[tex]-4(4t+3)(t-2)=0 \\\\t=-\dfrac{3}{4}, 2[/tex]
Since the time must be positive, it hits the ground after 2 seconds. Hope this helps!

Daily Pocket Money ($)
What is the mean daily pocket money?
*diagram of the dot plot is attached below
Answer:
$2.15
Step-by-step Explanation:
Mean daily pocket money or average daily pocket if the group if students shown in the for plot that is attached below = the sum of the pocket money received by the students ÷ the total number of students.
From the diagram of the dot box attached below, the total number if students = 13 (each dot represents a student)
Sum of the pocket money received by the students = 4(1) + 5(2) + 3(2) + 4(2)
= 4 + 10 + 6 + 8
Sum = 28
Therefore, mean daily pocket money = 28 ÷ 13 = $2.15

Answer:
x=5
Step-by-step explanation:
2x+10=20
-10 -10
2x=10
then divide both sides by 2
x=5
Answer:
x = 5
Step-by-step explanation:
Given
2x + 10 = 20
Subtract 10 to both sides
(2x + 10) -10 = 20 - 10
2x = 10
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{10}{2}[/tex]
x=5
Check your work. Substituted 5 for x
2x + 10 = 20
2(5) + 10 =20
10 + 10 = 20
20 = 20
Phillip is rolling two number cubes. How many different ways can he roll the number cubes and get a sum of 6?
A. 3
B. 4
C. 5
D. 6
We will find that there are 5 outcomes where the sum of the numbers on the dice adds up to 6.
In how many different ways can he roll a sum of 6?We want to see how many outcomes are there where the sum of the two dice is equal to 6. Each dice has 6 outcomes, which are:
{1, 2, 3, 4, 5, 6}
For rolling two dice with 6 outcomes each, the total number of outcomes is:
6*6 = 36
For rolling two dice, we can use the notation:
dice 1, dice 2
And we can also write the sum, so we will only look at the outcomes where the sum is 6.
dice 1, dice 2, Sum
1 5 1 + 5 = 6
5 1 5 + 1 = 6
2 4 2 + 4 = 6
4 2 4 + 2 = 6
3 3 3 + 3 = 6
So there are 5 outcomes where the sum is equal to 6, so the correct option is B
