which expression ae equivalent to this expresion 4x + 4

Answer:

The sequence is: Refection across y-axis, Horizontal Shrink, Horizontal Translation and Reflection across x-axis.

Step-by-step explanation:

Since, we are given f(x) = square root x.

The sequence of transformations which transform f(x) into g(x) is given by:

1. Reflection across y-axis i.e. f( x ) to f( -x )

2. Horizontal Shrinking i.e. f( -x ) to f( -x/2 )

3. Horizontal Translation i.e. f( -x/2 ) to f( -x/2 + 3 )

4. Reflection across x-axis i.e. f( -x/2 + 3 ) to -f( -x/2 + 3).

Step-by-step explanation:

[tex]3e^{2x} +5=27[/tex]

To take natural log ln , we need to get e^2x alone

Subtract 5 on both sides

[tex]3e^{2x}=22[/tex]

Now we divide both sides by 3

[tex]e^{2x}=\frac{22}{3}[/tex]

Now we take 'ln' on both sides

[tex]ln(e^{2x})=ln(\frac{22}{3})[/tex]

As per log property we can move exponent 2x before ln

[tex](2x)ln(e)=ln(\frac{22}{3})[/tex]

The value of ln(e) = 1

[tex]2x=ln(\frac{22}{3})[/tex]

Divide both sides by 2

[tex]x=\frac{ln(\frac{22}{3})}{2}[/tex]

x= 0.996215082

Final answer:

When the radius is doubled and the height is divided by 3 in the volume formula for a cone, the new volume is 4/3 of the original volume.

Explanation:

The student has provided the formula 1/3 π r^2 • h, which represents the volume of a cone.

To find the ratio of the new volume to the original volume after the radius (r) is doubled and the height (h) is divided by 3, we must substitute these changes into the formula and simplify.

Original volume formula is V = 1/3 π r^2 • h.

If the radius is doubled (2r) and the height is divided by 3 (h/3), the new volume formula becomes

V' = 1/3 π (2r)^2 • (h/3).

After simplification, the new volume becomes V' = 1/3 π 4r^2 • h/3, which further simplifies to V' = 4/9 π r^2 • h.

Therefore, the ratio of the new volume V' to the original volume V is 4/3.

Answer: Barlow has more by 178

Step-by-step explanation:

Solve for Barlow first: 4/9 of 873 is 388 boys.

Solve for Willow: since 2/3 of the students are girls, that means that 1/3 of them are boys: 1/3 of 630 = 210

Barlow has more, now find out by how many: 388 - 210 = 178.

Barlow School has a greater number of boys than Willow School, with 178 more boys.

To determine which school has a greater number of boys, we can calculate the number of boys in each school by using the given ratios. At Barlow School, 4/9 of the 873 students are boys. At Willow School, 2/3 of the students are girls, which means that 1/3 of the students are boys since there are only boys and girls at the school.

First, we calculate the number of boys at Barlow School:

Then, we calculate the number of boys at Willow School. Since 2/3 of the 630 students are girls, we need to find 1/3 to find the number of boys:

To find out which school has the greater number of boys, we compare the numbers:

Thus, Barlow School has a greater number of boys. To find out by how many, we subtract the number of boys at Willow School from the number of boys at Barlow School:

Answer:

the number is 70

Step-by-step explanation:

let unknown number is 'x'

given that 2x/7=20

multiply by 7 both sides

2x=20*7

divide by 2 on both sides

x=(20*7)/2

x=10*7

x=70

If the quotient of twice a number divided by 7 is 20, then the number is 70.

Let the number be represented as x

Twice the number = 2x

Twice a number divided by 7 = 2x/7

The quotient = 20

To get the value of x:

2x/7   =  20

Cross multiply:

2x  =  7(20)

2x  =  140

x   =  140/2

x  =   70

Therefore, if the quotient of twice a number divided by 7 is 20, then the number is 70.

Step-by-step explanation:

To find the tip, we multiply the tip percentage by the amount of the bill.  The tip percentage must be in decimal form.

.18* $50.00 = $9.00

The tip is $9.00

Answer:

The percentages are 267% and 400% respectively.

Step-by-step explanation:

To find the answers of these, you need to divide the second number by the first. This will give you the percentage.

2/3 ÷ 1/4 = 8/3 = 2.67 = 267%

You can do the same for the second one.

2/3 ÷ 1/6 = 12/3 = 4 = 400%

To determine what percentage 2/3 is of 1/4, calculate (2/3) / (1/4) * 100, resulting in 266.67%. To find the percentage 2/3 is of 1/6, calculate (2/3) / (1/6) * 100, resulting in 400%.

When finding the percent of a fraction, you are essentially calculating what part of 100 the fraction represents. To find what percent 2/3 is of 1/4, you need to set up a proportion such that 2/3 is to 1/4 as x is to 100.

To solve this, you divide 2/3 by 1/4 and then multiply by 100:

Percent = (2/3) / (1/4) * 100

Percent = (2/3) * (4/1) * 100

Percent = 8/3 * 100

Percent = 800/3

Percent = 266.67%

Similarly, to find what percent 2/3 is of 1/6, you can use the same approach by dividing 2/3 by 1/6 and then multiplying by 100.

Percent = (2/3) / (1/6) * 100

Percent = (2/3) * (6/1) * 100

Percent = 12/3 * 100

Percent = 400%

Therefore, 2/3 is 266.67% of 1/4, and 400% of 1/6.

given the first 3 terms of the geometric sequence - 4, 20, - 100

with r = [tex]\frac{-100}{20}[/tex] = [tex]\frac{20}{-4}[/tex] = - 5

the n th term formula ( explicit formula ) is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] [tex]r^{n-1}[/tex]

here r = - 5 and [tex]a_{1}[/tex] = - 4, hence

[tex]a_{n}[/tex] = - 4 [tex](-5)^{n-1}[/tex] with n ≥ 1

This question is solved using geometric sequence concepts, and doing this, we get that the correct option is:

[tex]a_n = -4(-5)^{n-1}, n \geq 1[/tex], second option

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is the same, called common ration, and the general equation is given by:

[tex]a_n = a_1q^{n-1}, n \geq 1[/tex]

In which [tex]a_1[/tex] is the first term and q is the common ratio.

[tex]a_n = a_1q^{n-1}, n \geq 1[/tex]

[tex]a_n = -4q^{n-1}, n \geq 1[/tex]

The common ratio is:

[tex]q = \frac{-100}{20} = \frac{20}{-4} = -5[/tex]

Reflection across y-axis followed by dilation with scale factor 4 and center (0,0).

Step-by-step explanation:

From the given figure it is noticed that the vertices of preimage are E(-2,1), F(-2,0) and G(-3,0). The vertices of image are E'(8,4), F'(8,0) and G'(12,0).

The triangle E'F'G' is enlargement of mirror image of EFG. Therefore reflect the triangle EFG across y-axis. If a point reflects across y-axis, then

[tex](x,y)\rightarrow (-x,y)[/tex]

The new vertices of the triangle are E(2,1), F(2,0) and G(3,0).

Length of FG is 1 unit and length of F'G' is 4 units. The scale factor is

[tex]\frac{F'G'}{FG}=\frac{4}{1}=4[/tex]

Length of OF is 2 unit and length of OF' is 8 units.

[tex]\frac{OF'}{OF}=\frac{8}{2}=4[/tex]

Rule of dilation with scale factor k and origin as center of dilation is defined as

[tex](x,y)\rightarrow (kx,ky)[/tex]

The vertices of image are E'(8,4), F'(8,0) and G'(12,0).

Since the distance ratio of image and preimage from the origin is same as the scale factor, therefore the center of dilation is origin.

Thus, the triangle EFG can form the triangle E’F’G’ using reflection across y-axis followed by dilation with scale factor 4 and center (0,0).

Notes: In this case dilation with scale factor 4 and center (0,0) followed by reflection across y-axis will give the same results.

Step-by-step explanation:

The question is about the probability of sum of numbers obtained after rolling two dice. There are 36 possible outcomes of a roll of two dice. The probability of the event that the sum of numbers obtained is 4 or greater than 9 is 1/4.

The subject of this question is probability, focusing specifically on the sample space and likely outcomes of two number cubes, or fair six-sided dice, being rolled. Part (a) of the question asks for the sample space which includes all possible outcomes of a roll of two dice i.e., (1,1), (1,2), ..., (6,5), (6,6). There are 36 possible outcomes in total.

For part (b), we are finding the probability of the event that the sum of the numbers obtained after rolling the two dice is 4 or the sum of numbers obtained is greater than 9. There are 3 ways to get a sum of 4, i.e., (1,3), (2,2), (3,1), and 6 ways to get a sum greater than 9, i.e., (4,6), (5,5), (5,6), (6,4), (6,5), (6,6). That's 9 favorable outcomes out of the total of 36. Therefore, the probability of the event is 9/36, which simplifies to 1/4.

The probability of getting a sum of 4 or a sum greater than 9 is determined by dividing the number of favorable outcomes by the total number of outcomes which is 13/36

The sample space of rolling two number cubes can be listed by considering all the possible outcomes when rolling two dice. Since each die has 6 sides numbered from 1 to 6, there are a total of 36 possible outcomes.

The probability of getting a sum of 4 or a sum greater than 9 can be calculated by determining the number of favorable outcomes and dividing it by the total number of outcomes.

In this case, there are 3 favorable outcomes for a sum of 4 (1+3, 2+2, 3+1) and 10 favorable outcomes for a sum greater than 9 (4+6, 5+5, 5+6, 6+4, 6+5, 6+6).

Therefore, the probability is (3+10)/36, which simplifies to 13/36.

Convert mixed number to improper fraction:

[tex]1\dfrac{3}{4}=\dfrac{1\cdot4+3}{4}=\dfrac{4+3}{4}=\dfrac{7}{4}\\\\4\dfrac{1}{6}=\dfrac{4\cdot6+1}{6}=\dfrac{24+1}{6}=\dfrac{25}{6}\\\\1\dfrac{3}{4}\times4\dfrac{1}{6}=\dfrac{7}{4}\times\dfrac{25}{6}=\dfrac{7\times25}{4\times6}=\dfrac{175}{24}=\dfrac{168+7}{24}=7\dfrac{7}{24}[/tex]

Final answer:

To solve 1 3/4 x 4 1/6, we convert the mixed numbers to improper fractions and multiply them, resulting in an incorrect statement that the answer is 1/4; the calculated multiplication is 175/24, which can be further simplified.

Explanation:

To solve the multiplication problem 1 3/4 x 4 1/6, we'll first need to convert the mixed numbers into improper fractions.

For 1 3/4, which is 1 + 3/4, we convert it to an improper fraction by multiplying the whole number by the denominator and adding the numerator, which gives us (1*4) + 3 = 7/4.

For 4 1/6, which is 4 + 1/6, we convert it to an improper fraction by doing the same process: (4*6) + 1 = 25/6.

Now, we multiply the two improper fractions: (7/4) x (25/6).

To multiply fractions, we multiply the numerators together and the denominators together:

7 x 25 = 175
4 x 6 = 24

So, (7/4) x (25/6) = 175/24.

Finally, we simplify the improper fraction by dividing 175 by 24, which results in a mixed number or a decimal.
