Answer:

  g(x) = 2^(x+3) -2

Step-by-step explanation:

To translate a function f(x) right h units and up k units, it becomes ...

  g(x) = f(x -h) +k

Here, your translation is (h, k) = (-3, -2), so the function becomes ...

  g(x) = f(x +3) -2

  g(x) = 2^(x+3) -2 . . . . matches the last choice

Step-by-step explanation:

Answer:

Part 17)

Ula's age is 7 years

Ola's age is 14 years

Ali's age is 3 years

Part 18) Zosia's age is 15 years

Part 19) All together are 36 years old

Step-by-step explanation:

The question in English is

17. Ula is twice as young as Ola and four years older than Ali. Together these three girls are 24 years old. How old is each of them?

18. Zosia's father is 3 times older than her and Zosia is 30 years younger than him.

How old is Zosia?

19. Julek and Asia are 6 years older than Michael, but each of them separately is younger than him: Julek by 7 years, Asia by 2 years. How old are they all together?

Part 17)

Let

x ----> Ula's age

y ---> Ola's age

z ---> Ali's age

we know that

Ula is twice as young as Ola

[tex]y=2x[/tex] ----> equation A

Ula is four years older than Ali

[tex]x=z+4[/tex]

[tex]z=x-4[/tex]----> equation B

Together these three girls are 24 years old.

so

[tex]x+y+z=24[/tex] -----> equation C

substitute equation A and equation B in equation C

[tex]x+2x+(x-4)=24[/tex]

solve for x

[tex]4x=24+4\\4x=28\\x=7[/tex]

Find the value of y

[tex]y=2(7)=14[/tex]

Find the value of z

[tex]z=7-4=3[/tex]

therefore

Ula's age is 7 years

Ola's age is 14 years

Ali's age is 3 years

Part 18)

Let

x ----> Zosia's father's age

y ----> Zosia's age

we know that

Zosia's father is 3 times older than Zosia.

so

[tex]x=3y[/tex]  ----> equation A

Zosia is 30 years younger than him.

so

[tex]y=x-30[/tex] ----> equation B

substitute equation A in equation B

[tex]y=3y-30[/tex]

solve for y

[tex]3y-y=30\\2y=30\\y=15[/tex]

therefore

Zosia's age is 15 years

Part 19)

Let

x ----> Julek's age

y ----> Asia's age

z ----> Michael's age

we know that

Julek and Asia are 6 years older than Michael

so

[tex]x+y=z+6[/tex] ----> equation A

Julek is 7 years  younger than Michael

[tex]x=z-7[/tex] ----> equation B

Asia is 2 years  younger than Michael

so

[tex]y=z-2[/tex] -----> equation C

substitute equation B and equation C in equation A

[tex](z-7)+(z-2)=z+6[/tex]

solve for z

[tex]2z-z=6+9\\z=15[/tex]

Find the value of x

[tex]x=15-7=8[/tex]

Find the value of y

[tex]y=15-2=13[/tex]

Adds the ages

[tex]x+y+z=8+13+15=36\ years[/tex]

therefore

All together are 36 years old

Answer:

The absolute error is 0.2

The percent error is 1.45

Step-by-step explanation:

Please kindly check the attached for explanation

The absolute error of the police officer's estimate is 0.2, and the percent error is approximately 1.5%

In Mathematics, absolute error is determined by the absolute value of the difference between the estimated value and the actual value. Therefore, the absolute error in this case is |14 - 13.8| = 0.2.

Percent error, on the other hand, is calculated by first finding the absolute error, then dividing the absolute error by the actual measurement, and finally multiplying the result by 100% to turn it into a percentage. So in this case, the percent error is given by (0.2 / 13.8) * 100 = 1.45%. Since we should round it off to the nearest tenths, the percent error will be roughly 1.5%.

Answer:

Y=40

Explanation:

Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8  y must equal 40.

6:30 = 8:40

or

30/6= 5

Y/8= 5

Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.

Answer:40

Step-by-step explanation:

6 times 5 is 30

so 8 times 5 = 40

Step-by-step explanation:

Mr Abbot's son mowed more of the lawn. In total, they mowed 19/28 or approximately 68% of the lawn. Hence, approximately 32% or 9/28 of the lawn still has to be mowed.

To find out who mowed more lawn and how much of the lawn is still left to be mowed, we need to compare the fractions and then add them together.

Mr. Abbot mowed 1/4 of his lawn and his son mowed 3/7 of it. To compare these fractions, you can turn them into decimals or percent by dividing the numerator (the top number) by the denominator (the bottom number). Doing that, we find Mr. Abbot mowed 0.25 (or 25%) of the lawn and his son mowed approximately 0.43 (or 43%) of the lawn. Therefore, the son has mowed more lawn.

To figure out how much lawn is still left to be mowed, we add up the fractions of the lawn that Mr. Abbot and his son mowed: [tex]1/4 + 3/7 = 7/28 + 12/28 = 19/28[/tex]. Thus, 19/28 of the lawn have been mowed, and to figure out what fraction is left, we subtract this number from 1 since 1 represents the whole or 100% of the lawn: [tex]1 - 19/28 = 9/28[/tex]. So, 9/28 of the lawn still needs to be mowed.

Substituting the solution (2,10) into both equations of the system shows that it does not satisfy either equation, hence it is not a valid solution.(Choice B.No)

To verify the solution of the system of equations, we can substitute the ordered pair (2,10) into both equations. Let's do this:

Since the ordered pair (2,10) does not satisfy either of the two given equations, we can say that (2,10) is not a solution of the system of the equations.

https://brainly.com/question/35467992

#SPJ3

The point (2,10) is not a solution to the system of equations -3x - 4y = 4 and -5x + y = 2, as it does not satisfy either equation when substituted.

To determine if the point (2,10) is a solution of the given system of equations:

-3x - 4y = 4

-5x + y = 2
we need to substitute x=2 and y=10 into each equation to see if the left-hand side equals the right-hand side.

For the first equation:

-3(2) - 4(10) = -6 - 40 = -46
which does not equal 4, therefore the point (2,10) is not a solution to this equation.

For the second equation:

-5(2) + (10) = -10 + 10 = 0
which does not equal 2, so (2,10) is also not a solution to the second equation.

Since (2,10) does not satisfy either equation, we can conclude that:

(Choice B)
No, (2,10) is not a solution to the system of equations.

Step-by-step explanation:

it starts out with 18 students, 24 pets in total. -16 for the dogs and cats, to lead up to 8, and 10 students left after subtracting 8 for how many students don't have a pet at home. So 2 students shouldn't have four legged pets left after subtracting the rest.  (this is my answer, it's probably wrong, i think you should wait for more,)

Answer:

y = -9.3

if they are complementary it is 45 degrees

if they are supplementary it is 90 degrees

Step-by-step explanation:

-12.7 = y -3.4

-12.7 + 3.4 = y -3.4 + 3.4

-9.3 = y

complementary angles equal to 90 degrees

supplementary angles equal to 180 degrees

vertical angles have same degrees

so 90/2= 45

180/2 =90

d. Twenty-three ninth graders and thirty-five twelfth graders prefer math.

e. Eighteen tenth graders prefer English and fourteen eleventh graders prefer math.

Answer:

Therefore, the correct options are;

b. and d.

Step-by-step explanation:

Here we have a table with blank boxes and totals from which we can fill the boxes;

For the 12th graders, we have a total of 67 pupils with 32 preferring English, therefore the number of the 12th graders that prefer math is 67 - 32 = 35 pupils

Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils

Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils

Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils

Answer:

Part 1) The graphs open downward

Part 2) The vertex is the point (-2,5)

Part 3) The axis of symmetry is x=-2

Step-by-step explanation:

step 1

we have

[tex]y=-\frac{1}{3}(x+2)^2+5[/tex]

This is a vertical parabola open downward (because the leading coefficient is negative)

The vertex is a maximum

step 2

The quadratic equation is written in vertex form

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

where

(h,k) is the vertex

so

In this problem

The vertex is the point (-2,5)

step 3

The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

The x-coordinate of the vertex is -2

therefore

The axis of symmetry is x=-2

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

[tex]d_t=2d[/tex]

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

[tex]Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days[/tex]

Now, we multiply the distance per day by the total number of days:

[tex]Distance, D=2d\times 16\\\\=32d[/tex]

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

Final answer:

The area of a regular hexagon with an apothem of 15 cm is approximately 1166.55 cm².

Explanation:

The area of a regular hexagon can be found by using the formula:

Area = (3 x apothem x side length) / 2

In this case, the apothem is given as 15 cm. We need to find the side length to calculate the area. The side length can be found using the formula:

side length = 2 x apothem / tan(180° / 6)

Using a calculator, we can find that the side length is approximately 25.98 cm. Plugging in the values into the area formula, we get:

Area = (3 x 15 cm x 25.98 cm) / 2 = 1166.55 cm²
