Charmaine pays $848 for landscaping rocks for a project. The cost per pound is 32 cents. How many pounds did she purchase? 0.265 2.65 26.50 2,650

Answer:

A= 28.27 ft²

Step-by-step explanation:

if its trying to find area for a circle then we use the formula A=πr²

A=π(3)²

A= 28.27 ft²

Answer:

the answer is 18.85ft

Step-by-step explanation:

the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:

C = 2πr

input the values you have into the formula

C= 2 x π x 3

(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)

put that into your calculator and youll get the answer

C= 18.8495559215

(i rounded the answer to two decimal places = 18.85ft)

Answer:

The factors are 3 and -9

Step-by-step explanation:

The given trinomial is [tex]x^2-6x-27[/tex].

We need to find two factors. We know that,

3(9) = 27

So,

[tex]x^2-6x-27[/tex] can be written as :

[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.

Hence, the factors are 3 and -9.

Answer:

The first option:

Down 5, left pi/2.

Step-by-step explanation:

Let's define the translations in a general way.

Horizontal shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

if N is positive, the shift is to the left.

if N is negative, the shift is to the right.

Vertical shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x) + N

If N is positive, the shift is upwards.

If N is negative, the shift is downwards.

In this case, we have the function:

f(x) = 6*Sin(2*x + π) - 5

Where the original function was something like:

h(x) = 6*sin(2*x)

Here we can already see the vertical shift is of minus 5 units, so the shift is 5 units down.

then we get:

f(x) = h(x) - 5 =  6*sin(2*x) - 5

Now we can apply a shift  to the left of  π/2 units, so we get:

f(x) = h( x + π/2) - 5 =  6*sin(2*(x +π/2) ) - 5

f(x) =  6*sin(2*x +π ) - 5

Then the correct option is:

Down 5, left pi over 2

Answer:

1.09x10^4

Step-by-step explanation:

Answer:

A, C

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7

Answer:

a) the first negative number will be -1

b) A, B and C

c) 0.3

Step-by-step explanation:

Answer:

C.   a = 6

Step-by-step explanation:

Use the Pythagorean theorem

[tex]a^{2} + 8^{2} = 10^{2}[/tex]

[tex]a^{2}[/tex] + 64 = 100

[tex]a^{2}[/tex] = 36

a = 6

Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.

The equation of a quadratic function, of vertex (h,k), is given by:

[tex]y = a(x - h)^2 + k[/tex]

In which a is the leading coefficient.

In this problem, the equation is:

[tex]x^2 - 20x + 24[/tex]

Placing it in vertex form, we would have:

[tex](x - 10)^2 + 24 + c[/tex]

Applying the square of the subtraction:

[tex](x - 10)^2 = x^2 - 20x + 100[/tex]

Hence, a number of -100 would have to be added to complete the square.

x=-1, y=1

Step-by-step explanation:

Answer:

( -1, 1 )

Step-by-step explanation:

To solve, graph the equations and find the point of intersection.

when graphed these equations intersect at (-1, 1)

To double-check and make sure it's correct, plug in a solve.

x = -1

y = 1

y = 2(-1) + 3

1 = 2(-1) + 3

1 = -2 + 3

1 = 1

y = x + 2

1 = (-1) + 2

1 = 1

Answer:

|GH| = 5,7 cm

Step-by-step explanation:

To know |GH|, you first need to find the length of |GD|.

We can calculate |GD| by;

cosG = |GC| / |GD|

<=> |GD| = |GC| / cosG

 => |GD| = 3,9 cm/ 0,62 = 6,33 cm

We now can easily calculate |GH| with the sinus of angle D;

sinD = |GH| / |GD|

<=> |GH| = sinD.|GD|

 => |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

Step-by-step explanation:

The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.
