Answer:

g(x) = (x-8)^2 - 5

Step-by-step explanation:

subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.

(x-8)^2 - 1  translates the function 8 units to the right

subtracting from the constant translates the function down and adding translates it up.

x^2 - 5 translates the function 4 units down

Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down

What is the y-intercept of a line that has a slope of 4 and passes through point (8, 3)?
3
Ο Ο Ο Ο
11

Answers

Answer:

The slope-intercept form: y = mx + b

m - a slope

b - y-intercept

We have a slope m = 1/4. Substitute: y = 1/4 x + b

We know, the line passes through point (8, 3) → x = 8, y = 3.

Put the values of x and y to the equation of the line:

1/4 · 8 + b = 3

2 + b = 3 |-2

b = 1

Answer: y-intercept is (0, 1)

A 20 ft tall ladder standing next to a statue casts a 12 ft shadow. If the statue casts a shadow that is 9 ft long then how tall is it?

Answers

Given that,

Length of the ladder = 20 ft

It casts a 12 ft shadow

To find,

If the statue casts a shadow that is 9 ft long then how tall is it?

Solution,

Let the ladder be x ft tall.

20 ft tall ladder = 12 ft shadow

9 ft tall ladder =

[tex]\dfrac{20}{12}\times 9\\\\=15\ ft[/tex]

Hence, the required length is 15 ft.

In ΔDEF, if DE ≅ DF and EF is the hypotenuse, then ΔDEF is
a acute and scalene. c. right and isosceles.
b right and scalene. d. obtuse and isosceles.

Answers

Answer:

C. Right and isosceles

Explanation:

Since two sides of the triangle are equal in length ([tex]DE[/tex] and [tex]DF[/tex]), this means that the triangle is an isosceles triangle. Since [tex]EF[/tex] is the hypotenuse of this triangle, it also means that the triangle is a right-angle triangle (the hypotenuse refers to the longest side of a right triangle). Therefore, we can conclude that ΔDEF is right and isosceles.

Hope this helps :)

Answer:

It is C.

Find the wing area of the model if the wing area of the actual plane is 300 ft2
.

Answers

Step-by-step explanation:

Length on model : Length on actual = 1 : 25

=> Area on model : Area on actual

= 1² : 25² = 1 : 625.

Therefore area on model = 300ft² * (1/625) = 0.48ft².

Answers

Answer: -3x

Step-by-step explanation: If you separate out each term on its own, 9 and x², and do the square root of each one, you are left with 3x. This is also coincidentally what the right side of this graph looks graphically. However, the line of 3x does continue past x=0, so the other side of this graph, -3x, fits this better.

I don't know what essay format looks like ;n;Having to be at school by 7:30 or 7:00 in the morning eventually turns teens and kids into zombies, and not in a healthy way. Most days, kids, especially teens, come home with loads of homework, causing them to go to bed late, leaving them with only a few hours of sleep. Early times such as these can also cause stress, which can lead to loss of sleep too. This means that kids and teens still have to get up early in the morning and sit through hours of learning with only a few hours of sleep. This can be extremely harmful to teens' health and grades. With this being said, later times such as 8:00, 8:30, or maybe even 9:00 would be a better option considering the health and standards of teens and kids. The reason for this is because schools always start in the mornings, and some teens can barely wake up for this movement, so they fall asleep when set to do work and tasks. Every school thinks that they can keep their kids awake by starting maybe an hour later than Elementary schools, well truthfully they're wrong. Many teens always stay up late, and nothing is going to stop them from it because they want to go to sleep when they feel like it is not a set time. The reason the kids that are falling asleep and not doing no work are called zombies. In our view, they are always "moaning" and are always looking tired and acting tired. Kids at school with barely any rest act and sometimes look the same exact way.
