Answer:

Step-by-step explanation:

g(2) = 4(2^2) -9 = 4(4) -9 = 7

f(7) = 7+7 = 14

f(g(2)) = 14

__

f(-2) = -2 +7 = 5

g(5) = 4(5^2) -9 = 4(25) -9 = 91

g(f(-2)) = 91

Step-by-step explanation:

Step one:

we are given the radius as

r=2cm, and the number of spheres is 50 in numbers

let us find the volume of one sphere and multiply the area by 50 to get the volume of the 50 spheres

Step two:

[tex]volume=4/3 \pi r^3[/tex]

[tex]volume=4/3*3.142 *2^3\\\\volume=100.5/3\\\\volume=33.5[/tex]

The volume of one sphere is 33.5in^3

Hence the volume of the 50 spheres will be

=33.5*50

=1675.7cm^3 approx.

Volume of the melted solution will be 1675.5 cm³.

  Radius of each metal sphere = 2 cm

Expression for the volume of the sphere is given by,

Volume = [tex]\frac{4}{3}\pi r^{3}[/tex]

Here, r = radius of the sphere

By substituting the value of radius in the expression,

Volume = [tex]\frac{4}{3}\pi (2)^3[/tex]

             = 33.51 cm³

Volume of the melted solution = Volume of 50 spheres

Volume of 50 spheres = 50 × (33.51)

                                      = 1675.5 cm³

    Therefore, Volume of the melted solution will be 1675.5 cm³.

Answer:

34.134%

Step-by-step explanation:

We start by calculating the z-scores

Mathematically;

z-score = (x-mean)/SD

for 352

z-score = (352-447)/95 = -95/95 = -1

For 447;

z-score = (447-447)/95 = 0/95 = 0

So the probability we want to calculate will be;

P( -1 < X < 0)

According to the emipirical rule, we want to calculate the proportion below 1 SD of the mean

According to the empirical rule, this is 34.134%

Answer:

the first one

Step-by-step explanation:

Think of it this way. If it needs to be greater than -11, that means there is some kind of restraint. that would be in this situation, its under a square root. if you plug in -11, it should equal 0, so it has to be x+11 under square root. The second one wouldn't work since that would make it square root of -22 and thats imaginary, same thing with all the others, when you plug in -11, the last 3 would come negative. the first one is the only one that cancels the negative and gives you 0

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

principal P= $1800

time t= 1 year

Final amount A=1857.60

rate r=?

Step two:

we are expected to solve for the rate, let assume the investment is a simple interest type.

A=P(1+rt)

solve for r we can substitute our data

1857.60=1800(1+r*1)

1857.60=1800+1800r

1857.60-1800=1800r

57.6=1800r

r=57.6/1800

r=0.032

0.032*100= 3.2%

This shows that the rate is 3.2%

Answer:

a. The system of equations is:

c+p=10

5c+4p=46

b. 6 cakes were sold.

Step-by-step explanation:

Let p be the number of pies and c be the number of cakes then according to given statements

[tex]c+p=10\ \ \ eqn\ 1\\5c+4p=46\ \ \ eqn\ 2[/tex]

Using eqn 1

c= 10-p

Putting in eqn 2

[tex]5(10-p)+4p=46\\50-5p+4p=46\\50-p = 46\\-p=46-50\\-p=-4\\p=4[/tex]

Putting p=4 in eqn 1

[tex]c+p=10\\c+4=10\\c=10-4\\c=6[/tex]

Hence,,

a. The system of equations is:

c+p=10

5c+4p=46

b. 6 cakes were sold.

Answer:

I am pretty sure it is a reflection over the x-axis followed by a translation of 1 unit left and 2 units down.

Step-by-step explanation:

I dont really have an explanation i just know this is the answer. I am on this problem too lol

Translated 1 unit right and 2 units up followed by a reflection across x-axis.

Given that, a parallelogram with vertices A(−2, 1), B(−4,−3), C(2,−5), and D(4,−1).

We need to find which sequence of transformations will result in a parallelogram with vertices.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or a geometric figure. The original shape of the object is called the pre-image and the final shape and position of the object is the image under the transformation.

Parallelogram has vertices A(−2, 1), B(−4,−3), C(2,−5), D(4,−1) while parallelogram A'B'C'D' has vertices A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

If a point X(x, y) is translated a units right and b unit up, the new point is X'(x + a, y + b).

If a point X(x, y) is reflected across the x-axis, the new point is X'(x, -y)

If parallelogram ABCD is translated 1 unit right and 2 units up (i.e. x + 1, y + 2), the new points is A'(-1, 3), B'(-3, -1), C'(3, -3), D'(5, -1). If a reflection across x-axis is then done, the new point is A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

Hence, translated 1 unit right and 2 units up followed by a reflection across x-axis.
