By similar triangles we can say...

h/14=5/3.5  multiply both sides by 14

h=70/3.5

h=20 ft

Answer:

The height of the birdhouse is 20ft

Step-by-step explanation:

Length of bird house shadow = 14 feet

Length of your friend shadow = 3.5 feet

Height of your friend = 5 feet

Height of the birdhouse = ?

To find the height of the birdhouse we will compare the quality of the two parameters.

Height of your friend / Length of your friend shadow = Height of the birdhouse / Height of the birdhouse

Therefore we have:

5ft/3.5ft = x/14ft

Cross multiple

3.5x = 70

x = 70/3.5

x = 20ft.

Therefore, the height of the birdhouse is 20ft

Let f(X)=3√x
SOVA2 [1]

g(x) = 3√(x-5) -1

The process of altering a graph to produce a different version of the preceding graph is known as graph transformation. The graphs can be moved about the x-y plane or translated. They may also be stretched, or they may undergo a mix of these changes.

Horizontal stretching: It means the graph is elongated or shrink in x direction.

Vertical stretching : It means the graph is elongated or shrink in y direction

Vertical translation : It means moving the base of the graph in y direction

Horizontal translation : It means moving the base of the graph in x direction

According to rules of transformation f(x)+c shift c units up and f(x)-c shift c units down.

Therefore, in order to  move the graph down 1 units, we need to subtract given function by 1 , we get

g(x) = 3√x -1

According to rules of transformation f(x+c) shift c units left and f(x-c ) shift c units right.

Therefore, in order to  move the graph left by 5 units, we need to add given function by 5 , we get

g(x) = 3√(x-5) -1

Help me with these 3 questions please. aH-
Vanyuwa [196]

Answer:

1) 2/7; 43; 3/7

2) C

3) 30; 30; 10; is not; 10; is not

Step-by-step explanation:

1) y + 4/7 = 6/7

y = 6/7 - 4/7

y = 2/7

17 + b = 60

b = 60 - 17

b = 43

6/7 = m + 3/7

m = 6/7 - 3/7

m = 3/7

2) 11.5 - x = 5.25

x = 11.5 - 5.25

x = 6.25

3) he can substitute 30 for t.

He can then multiply ⅓ by 30 to get a product of 10 (⅓ × 30 = 10).

Since 15 is not equal to 10, Harry's solution is not correct

Ruth works at a farmer's market and gets paid $50. she also gets paid $0.65 for each jar of jelly "j" she sells. which equation
34kurt

Answer:

Step-by-step explanation:

Ruth's salary is s(j), where s represents salary and j the number of jars she sells.

At the very beginning, she receives $50.  Only answer 'd' could be correct.

But also, the equation has the variable part 0.65j, or

$0.65j, which is directly proportional to the unit price of the jars of jelly.

*

Summing up the fixed and variable parts, we get

s = $50 + ($0.65j), or s = $50 + ($0.65/jar)j    This is Answer D.
