plays is in the shape of an
equilateral triangle shown below.
The side lengths are in inches.
Find x and y.

Answer:

rewrite f(g(-2))

plug in -2 in g(x)

g(x)=-2-3

g(x)=-5

now plug in -5 into f(x)

f(x)=-5^2

f(x)=25

25 is the answer

Answer:

-2x^3+6x^2

or simplified : -2x^2(x-3)

Step-by-step explanation:

Rewrite the statement as:

[tex]((x^2)(x-3))(-2)\\[/tex]

Distribute:

[tex](x^2*x-3*x^2)(-2)\\(-2)(x^3-3x^2)\\-2x^3+6x^2[/tex]

simplify by taking a common factor out, in this case, -2x^2:

The area of the rectangle in terms of x is 2x² - 8

A rectangle is a quadrilateral with four right angles in the Euclidean plane.

Given one side of the rectangle is 2x+4 and the perimeter is 6x+4

Let the other side be y.

We know that:

perimeter = 2 × (sum of two sides)

or, 6x + 4 =  2 (2x+4+y)

or,6x + 4 = 4x + 8 + 2y

or, 2x - 4 = 2 y

or, y = x - 2

Now area of the rectangle = product of sides =  (x - 2)(2x+4)

Area = 2x² - 4x + 4x - 8

or, Area = 2x² - 8

Hence the area of the rectangle in terms of x is  2x² - 8

Answer:

they all have a factor of 5

Step-by-step explanation:

to the right is P(z> Z)

so P(z>Z) = 0.9909

P(z< Z) = 1- 0.9909 = 0.0091

Closest values from a z-table

P(z< -2.37) = 0.00889 (-0.00011 away)

p(z< -2.36) = 0.00914 (+0.00014 away)

so the answer must be (c) since it is between -2.36 and -2.37

Natalie Albert deposited checks totaling $1,735,97 into her savings account, she withdrew $100.00 while depositing some coins. If her total deposit was $1,668.71 then Natalie deposited $32.74 in coins.

Two or more expressions with an Equal sign is called as Equation.

Let's call the amount Natalie deposited in coins "x".

We know that her total deposit was $1,668.71,

so we can write an equation:

1,735.97 - 100.00 + x = 1,668.71

Simplifying, we get:

1,635.97 + x = 1,668.71

Subtracting 1,635.97 from both sides, we get:

x = 32.74

Therefore, Natalie deposited $32.74 in coins.

The radius of the smaller gear is 15 feet, Option C is correct.

Velocity is defined as the rate of change of distance of a body with respect to time

We can use the relationship between linear velocity and angular velocity for gears to solve this problem:

v = rω

where v is the linear velocity, r is the radius of the gear, and ω is the angular velocity.

We are given the linear velocity of the larger gear, which is 17π/6 inches per second.

v = 17π/6 inches per second

ω = (34π/3) / 60 radians per second

the radius of the smaller gear is:

r = v / ω

= (17π/6) / ((34π/3) / 60)

= 17π/6×60/(34π/3)

=17π/6×60×3/34π

= 1/6 ×60× 3/2

= 180/12

=15 feet

Hence,  the radius of the smaller gear is 15 feet.

Answer:

Step-by-step explanation:

The amount of milk in cups that Samuel had after he made biscuits is 1/4 cups.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

Amount of milk Samuel had = 1 7/8 cups

Amount of milk used to make biscuits = 1 5/8 cups

We have to find the amount of milk left after he made the biscuits.

This is found by subtracting the total amount of milk by the amount of milk used to make the biscuits.

Amount of milk left = 1 7/8 - 1 5/8

                                = 2/8

                                = 1/4 cups

Hence 1/4 cups of milk will be left.

Domain: allrealnumbers

Range: f(x) <= -8

Step-by-step explanation:

This equation shows that this shape is a parabola that is opening downwards (because of the negative in the -5/6)

This means it has a highest point. The x+2 means the curve is shifted/slid/tranlated to the right 2 units and the -8 at the end shows that it is slid/shifted/translated down 8 units. So the curve only exists starting from -8 and going down. That is the range f(x) <= -8

All upward and downward opening parabolas have a domain of all real numbers.

Let's see

[tex]\\ \rm\rightarrowtail y=\dfrac{-5}{6}(x+2)^2-8[/tex]

[tex]\\ \rm\rightarrowtail x\in R[/tex]

Domain is R

Now

[tex]\\ \rm\rightarrowtail y=\dfrac{-5(x+2)^2}{6}-8[/tex]

Answer:

Let s = his speed on the outbound trip

Then s + 20 = his speed on the return trip

Let t = his travel time on the outbound trip

Then t - 10 = his travel time for the return trip

Given: d = 750

Since distance = speed x time, for the two trips we have

750 = s*t

750 = (s+20)(t-10)

Solve for t in the 1st equation, substitute in the 2nd:

750 = (s+20)(750/s-10)

Solve for s:

750 = 750 - 10s + 15000/s - 200

Simplify:

s^2 + 20s - 1500 = 0

Factor:

(s+50)(s-30) = 0

Take the positive solution, s = 30

So the rates are 30 kph and 50 kph
