If Triangle BAD is similar to Triangle DOG what do you know about the sides? Be specific.

1 answer:

6 0

Id say that the sides would also be similar due to SSS Theorem (Side-Side-Side) because if both triangles are similar then the sides should also be congruent

A cosine function has a period of 5, a maximum value of 20, and a minimum value of 0. The function is not a reflection of its pa

Alika [10]

Answer:

A: f(x)=10cos(2π/5 x)+10

Step-by-step explanation:

The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.

The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.

The remaining choice A matches the description.

you take a group of 20 people going to the movies. kids’ tickets cost $4 each, and adults tickets $6 each. your total cost is $9

brilliants [131]

The number of kids in your group is 12.

Step-by-step explanation:

Given,

Number of people = 20

Cost of each kid ticket = $4

Cost of each adult ticket = $6

Total spent = $96

Let,

x be the number of kids ticket

y be the number of adult ticket

According to given statement;

x+y=20 Eqn 1

4x+6y=96 Eqn 2

Multiplying Eqn 1 by 4

$4(x+y=20)\\4x+4y=80\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(4x+6y)-(4x+4y)=96-80\\4x+6y-4x-4y=16\\2y=16$

Dividing both sides by 2

$\frac{2y}{2}=\frac{16}{2}\\y=8$

Putting y=8 in Eqn 1

$x+8=20\\x=20-8\\x=12$

The number of kids in your group is 12.

Light travels 1.08 x 10 9 kilometers in one hour. How far does it travel in 2 hours?

ozzi

The distance traveled by the light in 2 hours is 2.16×10⁹ km.

<h3 /><h3>Distance:</h3>

This is the total length of space between two points covered by an object. Distance has no regard for direction as it is termed a scalar quantity. The S.I unit of distance is meter(m).

To calculate the distance traveled by the light in 2 hours, first, we need to calculate the speed of the light.

Formula:

S = d/t................. equation 1

Where:

S = speed
d = distance travelled

t = time

From the question,

Given:

d = 1.08×10⁹ km
t = 1 hour

Therefore,

s = 1.08×10⁹/1

s = 1.08×10⁹ km/h

The distance traveled in 2 hours is

d = 2×1.08×10⁹
d = 2.16×10⁹ km

Hence, the distance traveled by the light in 2 hours is 2.16×10⁹ km
