Answer 1

Answer:

See below for answers and explanations to the first 5 problems

Step-by-step explanation:

Problem 1:

cos(x) = 2/3

sec(x) = ?

sec(x) = 1/cos(x)

sec(x) = 1/(2/3)

sec(x) = 3/2

Problem 2:

sinβ = -5/6

cscβ = ?

cscβ = 1/sinβ

cscβ = 1/(-5/6)

cscβ = -6/5

Problem 3:

secφ = 2

tanφ = √3

sinφ = ?

secφ = 1/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ(1/secφ)

√3 = sinφ(1/2)

2√3 = sinφ

Problem 4:

secθ = 8

tanθ = 3√7

cscθ = ?

secθ = 1/cosθ

tanθ = sinθ/cosθ

cscθ = 1/sinθ

tanθ = sinθ/cosθ

tanθ = sinθ(1/cosθ)

3√7 = sinθsecθ

3√7 = sinθ(8)

(3√7)/8 = sinθ

cscθ = 1/sinθ

cscθ = 1/((3√7)/8)

cscθ = 8/(3√7)

cscθ = (8√7)/21

Problem 5:

sinθ = 2/√5

cosθ = 1/√5

tanθ = ?

tanθ = sinθ/cosθ

tanθ = (2/√5)/(1/√5)

tanθ = (2/√5)(√5)

tanθ = 2

Complete Question

Last Month's Vegetarian Sales

Total Sandwiches Sold 75

Total Income $712.50

How much does Carmen charge for the vegetarian sandwich?

Answer:

[tex]X=9.5[/tex]

Step-by-step explanation:

From the question we are told that:

Total Vegetarian Sandwiches Sold [tex]T_{vs}=75[/tex]

Total Vegetarian Sandwiches Income [tex]T_{vi}=$712.50[/tex]

Generally the equation for Cost of vegetarian sandwich is mathematically given by

[tex]X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}[/tex]

[tex]X=\frac{T_{vi}}{T_{vs}}[/tex]

[tex]X=\frac{712.50}{75}[/tex]

Answer:

y = |x+1.5|

Step-by-step explanation:

Start with the graph of y = |x|. To shift it left by 1.5 units, replace x with x+1.5.

General rules for shifting graphs:

Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)

Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts

Answers

Answer:

Company one charges $11 + $0.16 per min.

Then if you talk for x minutes, the cost will be:

C₁(x) = $11 + ($0.16 per min)*x

For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:

C₂(x) = $20 + ($0.11 per min)*x

Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.

C₁(x) = C₂(x)

$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x

($0.16 per min)*x - ($0.11 per min)*x = $20 - $11

($0.05 per min)*x = $9

x = $9/($0.05 per min) = 180 mins

If you speak for 180 minutes, the cost is the same in both companies.

Which function is best represented by this graph?

D. y = −1/2x + 3

Answers

Answer:

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Greg uses a triangular area of his back yard as a garden.If the area if his garden 1.248 square feet,whats the area of the garden?

Answers

Answer:

192 ft²

Step-by-step explanation:

Area of rectangular backyard = 1248 ft²

Width of backyard = 52 ft

Length = x

Area of rectangular backyard = Length * width

1248 = x * 52

x = 1248 / 52

x = 24 feets

Hence, x = height of triangular garden

Area of triangle = 1/2 base * height

Area = 1/2 * 16 * 24

Area = 192 ft²

Ever since e-commerce started rising in prominence, the value of the retail showroom has diminished significantly. After all, consumers no longer need to visit a store to see what types of products are available for purchase. Not only does a quick search on Amazon accomplish this goal within seconds, but the site also provides helpful resources such as customer reviews and recommendations. Nevertheless, the online retail model doesn't work the same way for all products. Consumers on the whole still visit showrooms when they're looking to buy big expensive items like cars or mattresses.Thanks to a new wave of startups, however, online retailers are beginning to break through these barriers of size and expense. While many consumers remain reluctant to purchase a car without driving it, online mattress sellers like Casper and Leesa Sleep are winning over thousands with a streamlined approach. Customers simply select the size they want, pay for it, and then wait for the mattress to arrive at their doorstep compressed into a single box. Most showrooms contain a variety of mattresses that can greatly fluctuate in price depending on what sales are happening at the moment. Customers then learn all these intricate details from assertive salespeople on the hunt for a commission.Today's online mattress sellers cut out this rigmarole by using simplified inventory and fixed prices. But that doesn't necessarily mean these brands provide customers with the best deal possible. For instance, a king from Casper costs $950, not exactly a bargain for a foam mattress. In fact, customers could likely get a better deal if they were simply willing to do some haggling at a showroom. For Casper's customers, though, the company's appeal lies in its convenience rather than its value. There's also little risk in trying out a compressed mattress: Casper offers free shipping, 100-day guarantees and free returns on all of their products. While it remains to be seen if these upstarts can take on the $14 billion U.S. mattress industry, Casper's $100 million in sales during its first year of operation suggests that they're certainly on the right track.Requried:a.
