Henry has x blue pens. Rachel has $5$ blue pens and $y$ black pens. Jake has $3$ times the total number of pens Henry and Rachel have. Write a simplified expression for the number of pens Jake has.
pen(s)
Answer:
Step-by-step explanation:
Henry X blue
Rachel 5 blue and Y black
Jack 3 times the total of pens ( blue & black)
So
X + 5 + Y for Henry and Rachel
Jack : 3( X + 5 + Y)
Jack has 3X + 15 + 3Y.
Pens of jack 3X + 15 Blue & 3Y black.

A circle has a center of (-6,0) and passes
through the point (-1,3). What is its radius?
Answer: 10
Step-by-step explanation:
Given that a circle has the center at
(6.0) and the circle passes through the point (2,−3).So the distance between these two points will give us the measure of the radius.So(x1,y1)=(6
So by using the distance formula the radius of the given circle is-r=√(x2−x1)2+(y2−y1)2r=√(2−6)2+(−3−0)2r=√16+9r=√25=5 unitsSo the diameter of the given circle is=2rd==2(5)d=10units
Let's see
Find distance between these points and radius
√(x_1-x_2)²+(y_1-y_2)²√(-6+1)²+(0-3)²√(-5)²+(-3)²√25+9√34 unitsFind the third fourth and eleventh terms of the sequence described by the rule A(n)=-2+(n-1)(5)
Answer:
8,13,48
Step-by-step explanation:
Third = A(3) = -2 + (3-1)(5) = -2 + 10 = 8
Fourth = A(4) = -2 +(4-1)(5) = -2 + 15 = 13
Eleventh = A(11) = -2 + (11-1)(5) = -2 + 50 = 48
Darnell collected data from two different sales teams in his department, each with four employees the results of the study, based on each workers age and sales, are listed in the tables below. Which of the following is a true statement
The correct statement states that the sales range for team 2 is greater than the sales range for team 1.
What is the range?The range is defined as the difference between the maximum value to the minimum value.
Team 1
Worker's Age Sales
25 30,000
27 29,000
28 32,000
33 35,500
Team 2
Worker's Age Sales
25 35,000
28 37,000
29 38,000
31 65,000
Range Team 1 = 38000 - 30000 = 8000
Range Team 2 = 65000 - 29000 = 36000
Thus, The sales range for team 2 is greater than the sales range for team 1.

1. Find the volume of the solid that results when the region enclosed by the given curves = ^(−2), = 0, = 0, and = 1 is revolved about the x-axis.
2. Find the volume of the solid that results when the region enclosed by the given curves = ^(−2), = 0, = 0, and = 1 is revolved about the y-axis.
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the x-axis and the y-axis is 0.77 and 0.7135.
What is the revolution of the curve?Revolving the region bordered by y = f(x) and the x-axis on the interval [a, b] around the x-axis generates the volume (V) of a solid.
The volume is given as
[tex]\rm Volume = \int _a^b \pi y^2 \ dx[/tex]
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the x-axis.
[tex]\rm Volume = \int _0^1 \pi (e^{-2x})^2 \ dx\\\\\\Volume = \int _0^1 \pi (e^{-4x}) dx\\\\\\Volume = \pi [\dfrac{e^{-4x}}{-4}]_0^1\\\\\\Volume = - \dfrac{\pi}{4} [e^{-4} - e^0]\\\\\\Volume = -\dfrac{\pi}{4} [-0.98168]\\\\\\Volume = 0.77[/tex]
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the y-axis.
[tex]\rm Volume = \pi \left [\int_{0}^{0.135} dy + \int_{0.135}^{1}\left ( \dfrac{\ln x}{-2} \right )^{2}dy \right ]\\\\Volume =0.71375[/tex]

The rotation of the triangle ABC 360 degrees about the y-axis forms a cone
How to determine the shape after rotation?From the question, we understand that the triangle ABC is a right triangle
The vertical cross-section of a cone is a right triangle.
This means that a right triangle can be rotated 360 degrees on one of its legs (opposite or adjacent) to form a cone
Hence, the rotation of the triangle ABC forms a cone

Which of the following are identities? Check all that apply.
Answer: A , C and D
Step-by-step explanation:
Adrian is planning to drive from City X to City Y. The scale drawing below shows the distance between the two cities with a scale of ¼ inch = 18 miles.
City X to City Y is 3 1/2 in.
If Adrian drives at an average speed of 30 miles per hour during the entire trip, how much time, in hours and minutes, will it take him to drive from City X to City Y?
Answer:
takes him 8.4 hrs
Step-by-step explanation:
if 1/4=18inch then 3 1/2=7/2 so 7/2 divide by 1/4=14 then 18 x 14=252
so distance is 252 miles
speed is 30mph so 252/30=8.4h
the answer might need the 0.4 in hrs too
Write the expression in exponential form.
Answer:
In exponential form given function is equal to [tex]N = b^{r}[/tex]
Step-by-step explanation:
We are given with function,
[tex]log_{b} ^[/tex] [tex]^{N} = r[/tex]
We have to express it in exponential form.
Consider,
[tex]log_{b}^[/tex] [tex]^ {N} = r[/tex]
exponential both side to the power of b as base of given log function is b.
we get
[tex]b ^{logb}[/tex] [tex]^ {N} = b^{r}[/tex]
[tex]N = b^{r}[/tex]
Therefore In exponential form given function is equal to [tex]N = b^ {r}[/tex]
Find the volume of the sphere shown. Give each answer round to the nearest cubic unit. 15 CM
Answer:
a
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )
here the diameter = 15, then r = 15 ÷ 2 = 7.5 , then
V = [tex]\frac{4}{3}[/tex]π × 7.5³
= [tex]\frac{4}{3}[/tex]π × 421.875
= [tex]\frac{4\pi (421.875)}{3}[/tex]
