Given the system of equations, match the following items.
Gre4nikov [31]

Step-by-step explanation:

  • x+y=-3

x = -3 -y

  • 2x -y = 0

2(-3 -y) =0

-6 -2y = 0

-2y = 6

y = -3

  • x = -3 -y

= -3 -(-3)

= -3+3 = 0

Please help me I really need help
Fofino [41]

Answer:

A, C

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work

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.

determine the radius of the cone ,if the voulime of the cone is 125 cm to the power of 3 and the height of the cone is 12cm. Rou
Salsk061 [2.6K]

For this case we have that by definition, the volume of a cone is given by:

V = \frac {1} {3} * \pi * r ^ 2 * h

Where:

r: It is the radius of the cone

h: It is the height of the cone

According to the statement data we have:

h = 12 \ cm\\V = 125 \ cm ^ 3

Substituting in the formula:

125 = \frac {1} {3} * \pi * r ^ 2 * 12

We cleared the radius:

3 * 125 = \pi * r ^ 2 * 12\\\frac {3 * 125} {12 \pi} = r ^ 2\\9.9522 = r ^ 2\\r = \pm \sqrt {9.9522}

We choose the positive value:

r = 3.1547

We round and we have that the radius of the cone is:

r = 3.16 \ cm

ANswer:

r = 3.16 \ cm
