7 0

Step-by-step explanation:

49 = -16t^2 + 56t

-16t^2 + 56t -49 = 0

(-4t +7) (4t -7) = 0

-4t+7 =0

t = 7/4

Explain why you might want to write very large and very small numbers like the ones in the example problem in scientific notatio
slava [35]

Answer:

Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x10^{11}. This is easier to write and understand. This is why the scientific notation is used over standard.

Ronald Dairo is helping the local indus-
nadya68 [22]

Answer:

Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.

Step-by-step explanation:

Papaya rosette pieces on first day = 5890

Papaya rosette Pieces on second day = 7020

Papaya rosette Pieces of third day = 8150

Let

a_1 = 5890\\a_2 = 7020\\a_3 = 8150

We can check if these numbers are part of a sequence.

In order to check, common difference will be found first.

d = a_2-a_1 = 7020-5890 = 1130\\d =a_3-a_2 = 8150-7020 = 1130

It can be observed that the common difference is same. When the common difference is same, the sequence is said to be an arithmetic sequence.

The formula for arithmetic sequence is given by:

a_n = a_1+(n-1)d

Putting the values

a_n = 5890+(n-1)(1130)\\a_n = 5890+1130n-1130\\a_n =4760+1130n

The formula for nth term can be used to find any term. As we have to find the number of papaya rosette pieces after two weeks which means that we need to find the number of pieces on 14th day.

So,

a_{14}= 4760+1130(14)\\a_{14} = 4760+15820\\a_{14} = 20580

Hence,

Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.

PLEASE HELP ME. ONLY GOT 10 MINS.
Vikki [24]

Answer:

Step-by-step explanation:

The ratio of the angle is how the angle relates to each other. Let's say that we try to relate Angle A, B, C and get 1 : 3 : 5. That means Angle B is three times Angle A and Angle C is 5 times Angle A

Thus we get the equation:

A

B = 3A

C = 5A

A + B + C = 180, since all the angles of the triangle is equal to 180 degrees

A + 3A + 5A = 180

9A = 180

A = 20 --> B = 3A = 60 --> C = 5A = 100

So Angle A is 20 degrees, Angle B is 60 degrees, and Angle C is 100 degrees.

Hope that helps!
