Which statement belongs in Step 4?

Answer:

g(x)=x²/4

Step-by-step explanation:

g(x)=ax²+bx+c

g(0)=0  => c=0

g(-2)=1 => 4a-2b=1;

g(2)=1  => 4a+2b=1   (+)

                8a=2   => a=1/4

4*1/4+2b=1=> b=0

=> g(x)=x²/4

Answer:

There are Equilateral, Isosceles and Scalene triangles

Step-by-step explanation:

When all three sides of a triangle are all the same length, it is a equilateral triangle. When only 2 of the sided are the same length, it is a isosceles triangle. When none of the sides are the same, it is scalene.

Answer:

15 presents

Step-by-step explanation:

42 cm / 14 presents = 3 cm / 1

3cm / 1 presents = 45 / 15

Answer:

15 presents

Step-by-step explanation:

Since we are using unit rate, we have to find out how many centimeters he uses for 1 present. Therefore 42÷14=3 So he uses 3 centimeters of paper for 1 present. Since he used 45 centimeters of paper we divide that by 3 to see how many presents is in 45 centimeters. When dividing the answer is 15. Therefore he wraps 15 presents

Answer:

x = 23.5°

Step-by-step explanation:

The 4 angles 90, 43, x , x lie on a straight angle, thus

90 + 43 + x + x = 180, that is

133 + 2x = 180 ( subtract 133 from both sides )

2x = 47 ( divide both sides by 2 )

x = 23.5°

Answer:

If Tobey gives the stickers out at random, what is the probability that the first child gets a scratch-n-sniff sticker and the second child gets a zoo animal sticker?

P(zoo 2nd | scratch 1st) = (9/25)(16/24) = (9/25)(2/3) = 6/25

I think the answer is b. cos(pi theta)= -0.6

The requried solution of the equations in the interval form are a. (-0.575, 0.575) and b. (0.71, 3.43).

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

a.

We can solve for theta by dividing both sides by 3, then taking the inverse cosine of both sides. Remember that there will be two solutions in the given interval because cosine has a period of 2π.

3cos(4Ф) = -2

cos(4Ф) = -2/3

4Ф = ±cos⁻¹(-2/3)

cos⁻¹(-2/3) ≈ 2.300

4Ф = ±2.300

Ф = ±0.575

Similarly,

b.

For cos(πФ)= -0.6
Ф=  0.71, 3.43

Thus, the requried solution of the equations in the interval form are a. (-0.575, 0.575) and b. (0.71, 3.43).

Answer:

n= 1/12

Step-by-step explanation:

1/6 ÷ 2

1/6×1/2=1/12

Two friends are sharing 1/6 of a pie. That's why it is 1/6 divided by 2. In fractions when you switch from division to multiplication, you switch the denominator and numerator, so 2/1 becomes 1/2. Then, you multiply 1/6 and 1/2. You end up with 1/12, so n= 1/12.

Each friend gets 1/12 of the pie.

Answer:

  6

Step-by-step explanation:

The work involved in making the poster is the product of students and hours:

  work = students × hours = (9 students)(10 hours) = 90 student·hours

__

If hours are reduced to 6, the necessary number of students is ...

  90 student·hours = (6 hours)(students)

  (90 student·hours)/(6 hours) = 15 students . . . . . . divide by 6 hours

If 15 are needed, then the number that must be added is ...

  15 -9 = 6 . . . . students need to be added

Answer:

Step-by-step explanation:

Given x and y are in proportion then the equation relating them is

y = kx ← k is the constant of proportion

To find k use an ordered pair from the table

Using (2, 10 ), then

10 = 2k ( divide both sides by 2 )

5 = k , thus

y = 5x ← relationship between x and y

Answer:

You can't do this without knowing the number of hours, but you can write an equation. The equation would be 12p. P means the number of hours they worked and 12 stands for how much they earn each hour. Therefore you would multiple both of them together.

Answer:7 ft

Step-by-step explanation:

inclination of slide [tex]\theta =60^{\circ}[/tex]

In [tex]\triangle PQR[/tex] we can write

[tex]\sin \theta =\frac{PQ}{PR}[/tex]

[tex]\sin 60=\frac{6}{PR}[/tex]

[tex]PR=\frac{6}{\sin 60^{\circ}}[/tex]

[tex]PR=\frac{6\times 2}{\sqrt{3}}[/tex]

[tex]PR=6.928\approx 7\ ft[/tex]

Step-by-step explanation:

because it gets bigger so they are not going to have the same measures or lenghts.

The statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B

When a shape is dilated, the orientation of the shapes is preserved but the side lengths of the shapes are not congruent

This means that the side lengths of triangle A'B'C are not congruent to triangle A'B'C

Hence, the statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B

Answer:

w=35

Step-by-step explanation:

See the angle to the right of 125? Put those angles together, and you get 180 degrees. For starters, we want to find the measure of the angle to the right of 125.

180-125=55

We can basically do this all over again to find w. The angle 55 + w + the square angle is 180 degrees. You can tell by the flat line. So we will find w like this:

180-90-55=w

Thus, w equals 35

The probability Kalya rolls an even number on the red cube and a multiple of [tex]3[/tex] on the blue cube is [tex]16%[/tex] percent, when both the cubes have faces labeled [tex]1[/tex] through [tex]6[/tex].

The ratio of the favourable number of outcomes to the total number of outcomes is known as Probablity.

First, find the possible outcomes.

Kalya has a red number cube and a blue number cube. Each number cube has faces labeled [tex]1[/tex] through [tex]6[/tex].

So, possible outcomes [tex]=(6[/tex]×[tex]6)=36[/tex]

Let, [tex]S[/tex] be the sample space.

Then, [tex]n(S)=36[/tex]

Let, [tex]E=[/tex]the event of getting an even number on the red cube and a multiple of [tex]3[/tex] on the blue cube.

[tex]E=(2,3),(2,6),(4,3),(4,6),(6,3),(6,6)[/tex]

Then, [tex]n(E)=6[/tex]

Let, [tex]P[/tex] is the probability of the event [tex]E[/tex].

So, [tex]P(E)=\frac{n(E)}{n(S)}=\frac{6}{36}=\frac{1}{6}[/tex]≈[tex]16[/tex] percent

Thus, the probability Kalya rolls an even number on the red cube and a multiple of [tex]3[/tex] on the blue cube is [tex]16[/tex] percent.

On photos i showed 2 ways of possible solutions

Answer: p=5

Step-by-step explanation:

6(3p-1)=84

You can now do it two ways. This is the first way:

Divide by 6 so the equation now writes:

3p-1= 14

Then add the one onto the other side.

3p=15

Then divide 15 by 3

P=5

The other way is to expand the brackets first.

18p-6=84

Then add the 6 onto the other side.

18p=90

Then divide 90 by 18.

P=5

This is a bit more complex so I recommend the first way. Hope you can now explain to your son. Have an amazing day!

Step-by-step explanation:

The expression (x²)⁴ without exponents can be written as x × x × x × x × x × x × x × x.

The given expression is (x²)⁴.

It is known that the power rule of exponents states that:

(xᵃ)ᵇ = xᵃᵇ

Here, a = 2 and b = 4.

So using the power rule,

(x²)⁴ = x²⁽⁴⁾

       = x⁸

Now, it is known that exponents are actually the multiplication of the number with the same number again and again.

Here x is multiplied by itself 8 times.

So the expression can be written as:

x × x × x × x × x × x × x × x.
