Answer:
9 × 2^(13)
Step-by-step explanation:
hello :
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r= -3-(-7)36/18 = 18/9 =2 A1 = 9
when : n =14 you have the 14rd term A14
A14 = 9 × 2^(14-1) = 9 × 2^(13)
The number of hours, h, it takes for a block of ice to melt varies inversely as the temperature, t. If it takes 3 hours for a
square inch of ice to melt at 60 degrees, find the constant of proportionality
a. 150
c. 210
b. 180
d. 200
Answer:
180
Step-by-step explanation:
hours = constant / temperature hours varies inversely as the temperature
3 = c / 60
c (constant) = 3 * 60 = 180

dylan has 128 prices of candy from Halloween . he eats half of his candy each week.
identify the function family .
creat a equation to model the scenario .
use equation to determine how much candy he will have after 9 weeks ?
Answer:
55.5 left over.
Step-by-step explanation:
128/2 = 64
half each week so;
1 whole = two weeks
8 weeks = 8
+ 1 = 8 1/2
so, 64/8.5
is going to be 55.5 left.

The graph of quadratic function f is shown on the grid. 5 -3 -12 5 u 6 Which of these best represents the domain of f? А -5.5 < x < 1.5 B All real numbers less than or equal to 3 C All real numbers D y <3
Answer:
C: All real numbers.
Step-by-step explanation:
Domain means the interval of x=values that the function resides in. Since this quadratic function can go to both positive and negative infinity, there are no limits to the x-values so therefore the domain is all real numbers.
To pass the time on his travels, Ibn Battuta decides to run a test to see if the mean caravan size passing through a certain outpost is greater than 20 camels. He records the sizes of 7 caravans that pass through, assume that this represents a simple random sample of all caravans. After noticing that a smaller number of caravans are significantly larger than the rest of the population, he concludes the population is quite different from normal. He does not know the population's standard deviation. Which of the following describe which kind of test he should run?
a. He should run a Z-test.
b. He should run a T-test, and approximating it with a normal distribution would be appropriate.
c. He should run a T-test, and approximating it with a normal distribution would be inappropriate.
d. None of the above would be appropriate tests.
In the given scenario, one can use only non-parametric tests as the distribution is not normal.
Statistically speaking, normality means the distribution of data or variables following a normal distribution, also known as a Gaussian distribution or bell curve.
a. Since the standard deviation of the population is not known, Z-test cannot be run.
b. According to the thumb rule, for approximation to normality by using the central limit theorem, the minimum sample size is required to be 30.
With a sample size of 7, normality cannot be assumed.
So, a t-test with approximating the distribution with normal distribution would not be appropriate to run.
c. Without normality assumptions, one can't run a t-test because the t-test's basic assumption is the normality of the distribution.
So, all the options are incorrect which leaves us with the option d. None of the above would be appropriate tests.

If f(x) = 3x+ 5 and g(x) = – 2x2 – 5x + 3, find (f + g)(x).
Answer: 1/8
Step-by-step explanation:(f÷g)(x) =
f(x) / g(x) =
2x / 22x
When we divide expressions with like bases, we subtract the exponents.
2(x - 2x) =
2-x
Now we substitute x = 3
So (f÷g)(3)
2-3
When we have a negative exponent, we perform the reciprocal of the expression and remove the negative sign from the exponent.

The height of a plant, in inches, p years after planting it is given by the polynomial function R(p)=−2p2+270p. Find the height of the plant when p=90 years.
Answer:
8100 inches
Step-by-step explanation:
A function assigns the values. The height of the plant after 90 years will be 8100 inches.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the height of a plant, in inches, p years after planting is given by the polynomial function R(p)= −2p²+270p.
Now, the height of the plant after 90 years can be written by substituting the value of p as 90. Therefore, the height of the plant after 90 years is,
R(p)= −2p²+270p
R(90)= −2(90)²+270(90)
= −2(8100) + 24,300
= −16,200 + 24,300
= 8100 inches
Hence, the height of the plant after 90 years will be 8100 inches.

Answer:
arc ABC = 196°
∠DCQ = 47°
Step-by-step explanation:
arc AD = 70°
∠D = 1/2 arc ABC = 98°
arc ABC = 98° * 2 = 196°
arc CD = 360° - arc AD - arc ABC = 360°-70°-196° = 94°
tangent chord angle DCQ = 1/2 arc CD = 1/2 * 94° = 47°

[tex]VW = 50[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find VW
To find VW, we make use of the following equivalent ratios.
[tex]YX : XW = ZX : XV[/tex]
Where:
[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]
[tex]XV = XW + VW = 25 + VW[/tex]
So, we have:
[tex]14 : 25 = 42 : 25 + VW[/tex]
Express as fraction
[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]
Divide both sides by 14
[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]
Cross multiply
[tex](25 + VW) * 1 = 3 * 25[/tex]
[tex]25 + VW = 75[/tex]
Solve for VW
[tex]VW = 75 -25[/tex]
[tex]VW = 50[/tex]
