find the volume of the prism
Answer:
The volume is: [tex]135m^3[/tex]
Step-by-step explanation:
Given
[tex]h = 5m[/tex] ---- height
[tex]l=9m[/tex] -- length
[tex]w = 6m[/tex] --- width
Required
Determine the volume (V)
The volume of a triangular prism is:
[tex]V = 0.5lwh[/tex]
So, we have:
[tex]V = 0.5 * 5m * 9m * 6m[/tex]

the population of a deer in the national park in model by the equation P = 300e^(it). If the population of the deer is 400 after 2 years, find the value of k. Round your answer to the nearest hundredth. NO LINKS!!!
Answer:
k ≈ 0.14
Step-by-step explanation:
Given
P = 300 [tex]e^{kt}[/tex]
Substitute P = 400 and t = 2 into the equation
400 = 300 [tex]e^{2k}[/tex] ( divide both sides by 400 )
[tex]e^{2k}[/tex] = [tex]\frac{4}{3}[/tex] ( take ln of both sides )
ln [tex]e^{2k}[/tex] = ln ([tex]\frac{4}{3}[/tex] )
2k = ln ([tex]\frac{4}{3}[/tex] ) ( divide both sides by 2 )
k = [tex]\frac{ln\frac{4}{3} }{2}[/tex] ≈ 0.14 ( to the nearest hundredth )
20. Given circle C with radius r and circle D with radius
s, what is an appropriate first step when proving
circle C is similar to circle D?
O A. Transform circle C with a dilation that has center
Cand scale factors.
B. Transform circle C with a dilation that has center
C and scale factor r.
O C. Transform circle C with the translation that maps
point Conto point D.
OD. Transform circle C with the translation that maps
point onto point C.
Answer:
A. Transform circle C with a dilation that has center C and scale factor s.
Step-by-step explanation:
Given
Circle C
[tex]radius = r[/tex]
Circle D
[tex]radius = s[/tex]
Required
Map C to D
From the question, we can assume that:
[tex]r \ne s[/tex]
This implies that options c and d are false because when an object is translated from one point to another, the size of the object remains unchanged.
To map C onto D,
1) C has to be dilated from its own center C
2) The scale of dilation will be equal to the radius of D (i.e. s)
Hence, (A) is correct
Answer:
It's C
Transform circle C with the translation that maps point Conto point D.

Jeff's bowling scores are approximately normally distributed with mean 100 and standard deviation 21, while Pam's scores are normally distributed with mean 155 and standard deviation 22. If Jeff and Pam each bowl one game, then assuming that their scores are independent random variables, approximate the probability that
a. the total of their scores is above 260.
b. Jeffs score is higher.
Answer:
a. 0.4364 = 43.64% probability that the total of their scores is above 260.
b. 0.0351 = 3.51% probability that Jeff's score is higher.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Sum/Subtraction between normal variables:
When two normal variables are added/subtracted, the mean is the sum/subtraction of the means, while the standard deviation is the square root of the sum of the variances.
a. the total of their scores is above 260.
Mean is the sum of the means, so:
[tex]\mu = 100 + 155 = 255[/tex]
Standard deviation is the square root of the sum of the variances. So
[tex]\sigma = \sqrt{21^2+22^2} = 30.4[/tex]
The probability is 1 subtracted by the p-value of Z when X = 260. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{260 - 255}{30.4}[/tex]
[tex]Z = 0.16[/tex]
[tex]Z = 0.16[/tex] has a p-value of 0.5636
1 - 0.5636 = 0.4364
0.4364 = 43.64% probability that the total of their scores is above 260.
b. Jeff's score is higher.
Jeff's mean is of 100, while Pam's is of 155. The probability of Jeff's score being higher is the probability that the subtraction is above 0. The mean is:
[tex]\mu = 100 - 155 = -55[/tex]
The probability is 1 subtracted by the p-value of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-55)}{30.4}[/tex]
[tex]Z = 1.81[/tex]
[tex]Z = 1.81[/tex] has a p-value of 0.9649.
1 - 0.9649 = 0.0351
0.0351 = 3.51% probability that Jeff's score is higher.

5. ¿Cuál es el resultado de simplificar a su minima expresión el siguiente
polinomio?:
2
3 3*
xy2 + 2x + 3xy2 + {x?y=5x
Answer:
El polinomio final es:
[tex]=x(\frac{1}{3}y^{2}-3+\frac{2}{3}xy)[/tex]
Step-by-step explanation:
Agrupemos los términos con las mismas variables:
[tex](\frac{2}{3}xy^{2}-\frac{1}{3}xy^{2})+(2x-5x)+\frac{2}{3}x^{2}y=[/tex]
Sumemos estos terminos:
[tex]=\frac{1}{3}xy^{2}-3x+\frac{2}{3}x^{2}y=[/tex]
Podemos ver que los tres terminos tienen x, asi que podemos factorizar x.
Por lo tanto el polinomio final es:
[tex]=x(\frac{1}{3}y^{2}-3+\frac{2}{3}xy)[/tex]
Espero te haya servido.
El resultado de simplificar [tex]\frac{2}{3}xy^2+2x-\frac{1}{3}xy^2+\frac{2}{3}x^2y-5x[/tex] es
[tex](\frac{1}{3}y^2+\frac{2}{3}xy-3)x[/tex]
El polinomio que queremos simplificar es
[tex]\frac{2}{3}xy^2+2x-\frac{1}{3}xy^2+\frac{2}{3}x^2y-5x[/tex]
primero, recopilamos términos similares
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2+\frac{2}{3}x^2y+2x-5x[/tex]
luego simplificamos los términos similares. Es decir
Para el [tex]xy^2[/tex] términos:
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2=(\frac{2}{3}-\frac{1}{3})xy^2\\\\=(\frac{1}{3})xy^2=\frac{1}{3}xy^2[/tex]
y para el [tex]x[/tex] términos:
[tex]2x-5x=(2-5)x\\=(-3)x=-3x[/tex]
la [tex]x^2y[/tex] términos ya está simplificado. Así que déjalo así.
Este es el trabajo total:
[tex]\frac{2}{3}xy^2-\frac{1}{3}xy^2+\frac{2}{3}x^2y+2x-5x\\\\=(\frac{2}{3}-\frac{1}{3})xy^2+\frac{2}{3}x^2y+(2-5)x\\\\=(\frac{1}{3})xy^2+\frac{2}{3}x^2y+(-3)x\\\\=\frac{1}{3}xy^2+\frac{2}{3}x^2y-3x[/tex]
Incluso podemos factorizar la respuesta final para obtener
[tex](\frac{1}{3}y^2+\frac{2}{3}xy-3)x[/tex]

Dividing the polynomial P(x) by x+5 yields a quotient Q(x) and a remainder 6 of . If Q(5)=2, find P(5) and P(-5).
9514 1404 393
Answer:
P(5) = 26
P(-5) = 6
Step-by-step explanation:
The remainder statement tells us ...
P(x) = Q(x)·(x +5) +6
Evaluating this for x=5, we get ...
P(5) = Q(5)(5+5) +6
P(5) = (2)(10) +6
P(5) = 26
And for x = -5, we have ...
P(-5) = Q(-5)(-5 +5) +6
P(-5) = 0 +6
P(-5) = 6

1. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:
"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."
Model the scenario with an equation. Let q be the number of quarters, d be the number of dimes, and n be the number of nickels.
25 q + 10 d + 5 n + 60 = 1.87
0.25 q + 0.10 d + 0.5 n + 0.60 = 187
q + d + n + 60 = 187
25 q + 10 d + 5 n + 60 = 187
2. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:
"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."
A. Simplify the equation that represents the value of the coins. Make it an equation that expresses the value of quarters, dimes, and nickels. Show your work.
B. Is it possible to have exactly 60 pennies in $1.87? Explain.
I will give brainliest if correct.
Answer:
I think the answer to this is: 25q + 10d + 5n + 60 = 87
The story says that you have 1 dollar and 87 cents; 60 cents of which is pennies. So, if you’re using an equation involving quarters, dimes and nickels, the total equation should equal to 87 cents (since that dollar bill could not be broken down to cents).
