Answer:
D: 21
Step-by-step explanation:
The first term is (a1). The third term is (a1)r². The product of these terms is ...
(a1)(a1)r² = ((a1)r)², the square of the second term.
The missing term is √(7·63) = √441 = 21.
_____
Additional comment
In consideration of the above, you can also see that the common ratio can be found from ...
a3/a1 = ((a1)r²)/(a1) = r² = 63/7 = 9
Then the common ratio is r = √9 = 3, and the second term is 7·3 = 21.

ALGEBRA Ishiro Murakami has $15.60 deducted weekly for
family medical insurance. His employer pays 85% of the cost.
What is the annual premium?
Murakami's Annual premium which is the total value of medical insurance in a year is $5408
Percentage paid by employer = 85%Percentage paid by worker = 15%Number of weeks in a year = 52Annual deduction from worker's salary = 52 × 15.60 = $811.2
15% of annual premium = 811.2
Let annual premium = p
Therefore,
15% × p = 811.2
0.15p = 811.2
Divide both sides by p
p = 811.20 / 0.15
p = $5408
Therefore, his annual premium is $5408

Point upper D left parenthesis negative 3 comma 5 right parenthesis. is a vertex of triangle DEF. After a rotation of the triangle about the origin, upper D prime is located at left parenthesis 3 comma negative 5 right parenthesis. Which of the following was the rotation of the triangle?
The rotation that the triangle DEF underwent is defined as follows:
180º around the origin.
RotationA rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.
A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:
90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)In this problem, the coordinates are given as follows:
Original: (-3,5).Image: (3,-5).Hence the rule is:
(x,y) -> (-x, -y).
Meaning that a rotation of 180º around the origin was done.

Calculus, second derivative. Please help! Show work, if possible please. Thanks! :)
Answer:
y''=sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)
Step-by-step explanation:
we are given y= csc x sec x
We use the rule for multiplying derivatives and the knowledge that the derivative of csc is -csc*cot and the derivative of sec is sec*tan to get
csc(x)*sec(x)*tan(x)+sec(x)*-csc(x)*cot(x)
which simplifies to
csc(x)*sec(x)*tan(x)-sec(x)*csc(x)*cot(x)
Using the same rules again (in tedium so they are not listed but can be inferred) we find the second derivative is
sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)

-10
Step-by-step explanation:
-8w-7=9
add 7 to both sides
-8w=16
divide by negative 8 on both sides
w=-2
w-8=-10
On simplifying,
-8w - 7 = 9
-8w = 16
w = -2
then,
= w - 8
= -2 - 8
= -10.

Internet rates for two companies are shown in the table. After how many months of
service is the total cost the same no matter which company is used? What is this total
cost?
Intemet Service Provide
Charges
Tyson's Ethernet $100 activation fee plus $20 per month
Darriana's DSL
$30 per month
A 10 months, $300
B 20 months, $600
C 30 months, $700
D 2 months, $60
100+(20×10)=300
30×10 =300
months = 10
The total cost becomes the same after 20 months of service, and the total cost is $600.
To find out when the total cost becomes the same for both companies, we need to compare their cumulative costs over time.
Tyson's Ethernet has an activation fee of $100 plus $20 per month, while Darriana's DSL costs $30 per month.
Let's set up equations for both companies:
For Tyson's Ethernet:
Total cost = Activation fee + Monthly charges
Total cost = $100 + ($20/month) * months
For Darriana's DSL:
Total cost = Monthly charges
Total cost = ($30/month) * months
We want to find when these two total costs are equal:
$100 + ($20/month) * months = ($30/month) * months
Now we can solve for the number of months:
$100 + ($20/month) * months = ($30/month) * months
$100 = ($30/month - $20/month) * months
$100 = $10/month * months
months = $100 / $10
months = 10
So, it takes 10 months for the costs to be equal. Now let's find the total cost at that point:
Total cost = ($30/month) * months
Total cost = ($30/month) * 20 months
Total cost = $600
Therefore, after 20 months of service, the total cost is the same for both companies, and the total cost is $600.
