Answer:

Perimeter = 42 cm

Step-by-step explanation:

A square has all equal sides so you would just add 10.5 + 10.5 + 10.5 + 10.5 to get 42 cm.

A company’s profit is equal to revenue minus cost. For one company, the yearly revenue is $32 million. What function rule descri
Naily [24]

Answer:

p=32-c (*Units in million $)

Step-by-step explanation:

Let r be the revenue realized in any given year.

-Given that c=cost and p= revenue

#We notice that the profit, cost or revenue realized in one year is independent of the prior or subsequent year.

-Therefore, the revenue function is independent of time and is expressed as:

p=r-c\\\\r=32\\\\\therefore p=32-c

Hence, the yearly profit for any given year is expressed as p=32-c (*Units in million $).

In RST, the measure of
hammer [34]

Answer:

5.2 feet.

Step-by-step explanation:

The useful equation to use for this problem is sine. Given the angle of measure 64 degrees, we have O (opposite) and H (hypotenuse).

From SOH CAH TOA, we see that we have O and H, so thus we should use sine.

Sine of any angle= opposite/hypotenuse.

Sine of 64= x/5.8

Sine of 64 (times 5.8)=x

x= 5.2 feet.

Additionally, you could use a right triangle calculator to solve for side x.

lana66690 [7]

Answer:

615.44 in^2

Step-by-step explanation:

10 is the circumference

14 in is the radius (as said the in the equation)

right now the circumference doesn't matter

remember ---> A=\pi r^{2}

plug in the values

A = 3.14(14)^2

solve.

A = 615.44 in^2

therefore the answer is 615.44 in^2

Use the discriminant to determine the number of real solutions to the quadratic equation.
Naily [24]

Answer:

0

Step-by-step explanation:

Use discramnt formula

b {}^{2}  - 4ac

Where 6 is a, 11 is b and 9 is c

11 {}^{2} - 4(6)(9)

121 - 216 =  - 95

Since the discramnt is negative, there are no real solutions and it will only produce imaginary solutions
