Answer:
g(x) = x+2
Step-by-step explanation:
f(x) = x^2 + 1
fg(x) = x^2 + 4x + 5
Find the function g(x) so that when you put it into f(x) you get x^2 +4x + 5
g(x) = x+2

What is the equation of the line that passes through the point (3, 4) and has a slope of 1?
Answer:
y = x + 1
Step-by-step explanation:
(3, 4); m = 1
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = 1(x - 3)
y - 4 = x - 3
y = x - 3 + 4
y = x + 1
Claire has invested $10,000 in an 18-month CD that pays 6.25%. How much interest will Claire receive at maturity?
Answer:
the interest received is $957.03
Step-by-step explanation:
Given that
The invested amount is $10,000
There is 18 months
And, the interest rate is 6.25%
= (($10,000 × (1 + 6.25% ) × 0.0625 × 6 months ÷ 12 months)) + ($10,000 × 6.25%)
= $332.03 + $625
= $957.03
Hence, the interest received is $957.03

3a. The average for the statistics exam was 75 and the standard deviation was 8.
Andrey was told by the instructor that she scored 1.5 standard deviations below
the mean. What was Andrey's exam score?
Answer:
63
Step-by-step explanation:
The formula to when given the number of standard deviations below the mean x =μ - nσ
Where:
x = raw score
μ is the population mean = 75
σ is the population standard deviation = 8.
n = number of standard deviations below the mean
Hence
x = 75 - 1.5 × 8
x = 75 - 12
x = 63
Therefore, Andrey's exam score is 63

Ken has 7 baseballs. Each baseball weighs 0.3 pound. Ken wants to use this
model to find the total weight of the baseballs. Each hundredths block in the
model represents 1 whole.
Use the drop-down menus to explain how Ken can use the model to find the total
weight of the baseballs. Click the arrows to choose an answer from each menu.
To represent the weight of one baseball, 0.3 pounds, Ken should shade 3
Choose...
To represent the weight of all of the baseballs, he should
shade this amount Choose... times. The shaded part of the model will represent
the expression Choose... The total weight of the baseballs is 7.3
pounds
My Progress
Answer:
2.1 pounds
Step-by-step explanation:
Given that :
Number of baseballs = 7
Weight of each baseball = 0.3 pounds
1 block = 0.1 pounds
Hence, each ball will represent 0.3 / 0.1 = 3 blocks
Hence, 3 blocks = 1 ball
7 balls will be : 3 * 7 = 21 blocks
Recall:
1 block = 0.1
Hence, 0.1 * 21 = 2.1
Therefore, the weight of the 7 balls = 2.1 pounds

OA 25 cm3
OB.
75 cm
O C.
105 cm
OD. 135 cm
E.
225 cm
Answer:
A. 25 cm^3.
Step-by-step explanation:
Volume = 1/3 * area of base * perpendicular height,
= 1/3 * 5^2 * 3
= 5^3
= 25.
The correct option is A. Volume of the pyramid is 25 cm³ which is option A.
What is the volume of the pyramid?
The volume of a pyramid is given by lbh/3. It is also given by the product of the base area and height of the pyramid and then divided by 3.
The base of the pyramid is in the form of a square as all sides are 5 cm. Find the area of the square that is the base area.
5×5=25 cm²
Now multiply 25 by the height of the pyramid which is 3 cm.
25×3=75 cm³
Divide 75 by 3 to find the volume of the pyramid.
75÷3=25 cm³
Thus, the volume of the pyramid is 25 cm³ which is option A.

Anya rolls an octahedron labelled A A A B C C C C what is the probability the octahedron will land on each letter
Answer:
the probability the octahedron will land on A is 3/8
the probability the octahedron will land on B is 1/8
the probability the octahedron will land on C is 4/8 or 1/2
Step by Step explanation:
All u have to do to figure this out is to first count the total amount of letters and in this case there are 8. To find the probability of a specific letter, you have to count how many of that letter there is in the total of 8. For example the letter A's probability is 3/8 since there are 3 A's and 8 letters in total.

It says the scale is 1:6, so we can multiply 15 square cm to, 15 x 6 = 90 square cm!
Hope this Helps! :)
Answer:
A. 90 square cm
Step-by-step explanation:
The scale factor is 1:6
So the scale drawing on the left is the 1.
The object on the right is 6.
The area of the scale drawing is 15 square cm. If we multiply that by 6, we get answer A. 90 square cm.

Find the measure of d . A. 50 B. 100 C. 40 D. 20
Answer:
A. 50
Step-by-step explanation:
< A and < D are both subtended on the circumference by the chord CB.
The measure of angle d is [tex]50^{0}[/tex].
What is circle circumference angle?An angle at the circumference of a circle is half the angle at the center standing on the same arc.
Two angles at the circumference standing on the same arc are equal.
According to the given figure
Circumferential angles are ∠CDB and ∠CAB.
And we have to find the measue of angle d i.e. ∠CDB.
Since, the angles of circumference corresponding the same arc are equal.
Here, ∠CAB and ∠CDB are the circumferential angles corresponding to arc.
Therefore,
m ∠CDB = ∠CAB = [tex]50^{0}[/tex]
⇒ d = m ∠CDB = [tex]50^{0}[/tex].
Hence, the measure of angle d is [tex]50^{0}[/tex].

Given s(t)= -t^3+2t^2+(3/2) be the position of a particle moving along the x-axis at time t. At what time will the instantaneous velocity equal the average velocity over the time interval (0,4)?
Answer: [tex]\dfrac{16}{9}\ s[/tex]
Step-by-step explanation:
Given
[tex]s(t)=-t^3+2t^2+\frac{3}{2}[/tex]
Average velocity is given by
[tex]v_{avg}=\dfrac{\int vdt}{\int dt}[/tex]
[tex]v_{avg}=\dfrac{-\frac{t^4}{4}+\frac{2}{3}t^3+1.5t}{t}\\\\v_{avg}=-\frac{t^3}{4}+\frac{2}{3}t^2+1.5[/tex]
Now, equate the average and instantaneous velocity
[tex]-\frac{t^3}{4}+\frac{2}{3}t^2+1.5=-t^3+2t^2+1.5\\\\\Rightarrow -\dfrac{3t^3}{4}+\dfrac{4t^2}{3}=0\\\\\Rightarrow t^2\left(-\dfrac{3}{4}t+\dfrac{4}{3}\right)=0\\\\\Rightarrow t=\dfrac{16}{9}\ s[/tex]

Answer:
.01*.5ˣ
Step-by-step explanation:
we can see that x=0 y= .01
so in our equation
a*bˣ
a=.01
This is throuhg plugging in 0 for x
a*b⁰=.01
a*1=.01
a=.01
Now it's just a matter of finding b
to do this just plug in a value
we know that when x=1 y=.005
.01*b¹=.005
b= .5
So our final equation is : .01*.5ˣ
