Answer:

24

Step-by-step explanation:

2³ + 4²

Solve for exponents first.

2³ = 2 × 2 × 2 = 8

4² = 4 × 4 = 16

8 + 16

Addition.

= 24

for questions 8 and 9, you just need to use a ruler to fine how many inches, centimeters, or millimeters each line segment is. (make sure to properly read the question to see if they’re asking for the measurement in in, cm, or mm.) i won’t be able to give you these measurements because the picture became smaller when you uploaded it, but it shouldn’t be that hard for you!

for question 10, use a ruler to draw and label your own line segment.

on 10a, draw a line segment that is 3 1/4 inches long, then label one end of the segment ‘H’ and one end ‘J’

for 10b, draw a line segment that is 5 7/16 inches long, then label one end of the segment ‘M’ and the other ‘N’.

Step-by-step explanation:

There are 12 beads.  2 are blue, 1 is green, 3 are purple, and the rest (6) are red.

So there are 9 beads that are purple or red.

The probability is therefore 9/12, which reduces to 3/4.

Answer:

Show all colored beads on the bottom draw a line in the middle and in the top show all red and purple colored beads.

Step-by-step explanation:

Well first we need to work out the number of beads total.

2 blue + 1 green + 3 purple + 6 red = 12

9 purple or red,

9/12

Simplified,

3/4

Show all colored beads on the bottom draw a line in the middle and in the top show all red and purple colored beads.

Answer:

Step-by-step explanation:

The product of distances to the circle along a secant is the same for all secants intersecting a given point.

a. Secants SW and QT intersect at U. Thus ...

  (UT)(UQ) = (US)(UW)

  (1.5)(4) = (SU)(3)

  SU = (4)(1.5)/3

  SU = 2

__

b. Secants PT and PX intersect at P. Thus ...

  (PQ)(PT) = (PR)(PX)

  PX = (PQ)(PT)/PR) = (2.5)(2.5 +4 +1.5)/3 = 20/3

  PX = 6 2/3

Answer:

Following system of equations have exactly one solution:

[tex]2 x + 4 y = 6\\ 3 x - 4 y = 9[/tex]

Step-by-step explanation:

Given 4 system of equations:

1st  

[tex]4 x + 2 y = 8\\ -4 x -2 y = 3[/tex]

2nd

[tex]-5 x + y = 6\\ 5 x - y = - 6[/tex]

3rd

[tex]- 3 x + 4 y = 2\\ 3 x - 4 y = 0[/tex]

4th

[tex]2 x + 4 y = 6\\ 3 x - 4 y = 9[/tex]

To find: Which system of equations has only one solution?

Solution:

First of all, let us learn the concept.

Let the equation of lines be:

[tex]a_1x+b_1y+ c_1=0[/tex] and  [tex]a_2x+b_2y+ c_2=0[/tex]

1. No solution:

There exists no solution if:

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq\dfrac{c_1}{c_2}[/tex]

2. Infinite solutions:

There exist infinitely many solutions if:

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]

3. One solution:

There exists one solution if:

[tex]\dfrac{a_1}{a_2}\neq\dfrac{b_1}{b_2}[/tex]

Now, let us consider the given equations one by one.

1st system of equations:

The ratio is:

[tex]\dfrac{4}{-4} , \dfrac{2}{-2} , \dfrac{8}{3}\\-1 =-1\neq \dfrac{8}{3}[/tex]

So, no solution.

2nd system of equations:

The ratio:

[tex]\dfrac{-5}{5} , \dfrac{-1}{1} , \dfrac{6}{-6}\\-1 =-1=-1[/tex]

So, infinitely many solutions.

3rd system of equations:

[tex]\dfrac{3}{-3} , \dfrac{-4}{4} , \dfrac{0}{2}\\-1 =-1\ne0[/tex]

So, no solution.

4th system of equations:

[tex]\dfrac{2}{3} , \dfrac{4}{-4} , \dfrac{6}{9}\\\dfrac{2}{3} \ne-1[/tex]

Hence, only one solution.

So, the answer is:

Following system of equations have only one solution:

[tex]2 x + 4 y = 6\\ 3 x - 4 y = 9[/tex]

Answer:

4

Step-by-step explanation:

Answer:

169

Step-by-step explanation:

f(x) = x^2, g(x) = x + 6, h(x) = 7

f(g[h(x)])

Replace h(x) with 7

f(g(7))

g(7) = 7+6 = 13

Replace g(7) with 13

f(13) = 13^2 = 169

Answer:

169

Step-by-step explanation:

We are asked to find:

f(g[h(x)])

We know that  f(x) = x^2, g(x) = x + 6, and h(x) = 7

Therefore, we can begin by substituting 7 for h(x)

 f(g[h(x)]), h(x)=7

f(g[7])

Now, we must find g(7). We know that g(x) is x+6

g(x)=x+6

We want to find g(7). Plug 7 in for each x.

g(7)=7+6

Add 7 and 6

g(7)=13

Substitute 13 in for g(7)

f(g[7])

f(13)

Finally, find f(13). We know that f(x)=x^2

f(x)=x^2

We want to find f(13). Plug 13 in for each x.

f(13)=13^2

13^2= 13*13= 169

f(13)=169

169

Therefore, f(g[h(x)]) is 169

Answer:

y = 3x -2

Step-by-step explanation:

y intercept means the point x = 0

need not be confused in that

we can get the two coordinates as

( 2, -4) and ( 0, -2)

gradient is difference of y/ difference of x

-2+-4/0-2

-6/-2 indeed its 3

so as y intercept is -2

c = -2

y = 3x - 2

The correct answer is B

Answer:

12b^2+4ab−3ba−6

Step-by-step explanation:

12b2+4ab−3ba−6

The two middle terms are like terms, the order in which you multiply does not matter ab =ba

12 b^2 +4ab -3ab -6

12 b^2 +ab -6

The correct answer is....

If the degree and variables of two terms are same, then they are called like terms.

Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.

By combining like terms we get

In options B, C and D, there are no like terms, So only the expression  we can simplify by combining like terms.

Answer:

The ball will reach the ground when h=0.

Set the equation equal to 0.

[tex]0=-8(2 t-4)(t+1)[/tex]

[tex]t=-1,2[/tex]

Step-by-step explanation:

The height of a golf ball after it has been hit from the top of a hill can be modeled by the equation

[tex]h=-8(2 t-4)(t+1)[/tex],

where h is the height in feet and t is time in seconds.  

When ball will reach the ground the distance between ball and ground is 0. So, the ball will reach the ground when h=0.

To find the time it takes for the ball to reach the ground,  set the equation equal to 0 and use the Zero Product Property to solve for $t$.

[tex]h=-8(2 t-4)(t+1)[/tex]

[tex]\Rightarrow 0=-8(2 t-4)(t+1)[/tex]

Solve the equation using the Zero Product Property.

[tex]2t-4=0\Rightarrow t=\dfrac{4}{2}=2[/tex]

[tex]t+1=0\Rightarrow t=-1[/tex]

So, [tex]t=-1,2[/tex]

Answer:  Area of Fountain = 147/147.58

Explanation:

The transformations of translation, reflection and rotation are considered rigid motions. They keep the figure the same size just it has been shifted around in some way. In contrast, a dilation will alter the size to make it larger or smaller depending on what the scale factor is.

Only choice C has "dilation" as part of the answer, so it must be the answer. The other choices are purely rigid motions that will keep the triangle the same size and shape. In other words, the preimage and image are congruent for choices A,B, and D.
