5 0

Menjawab:

15cm

Penjelasan langkah demi langkah:

Keliling segitiga adalah jumlah semua sisi segitiga

P = s1 + s2 + s3

Diberikan sisi jika segitiga;

S1 = 5cm

S2 = 7cm

S3 = 3cm

Keliling = 5cm + 7cm + 3cm

Keliling = 15cm

Oleh karena itu, keliling segitiga tersebut adalah 15 cm

For the function y=-2x^2+4x+1, what are the coordinates of the vertex? Is it a maximum or minimum point? Hint: use the vertex/ax
masya89 [10]

Step-by-step explanation:

y = -2x² + 4x + 1

Complete the square.

y = -2 (x² − 2x) + 1

y = -2 (x² − 2x + 1) + 1 − (-2)(1)

y = -2 (x − 1)² + 3

The vertex is (1, 3).  The leading coefficient is negative, so the vertex is a maximum.

Help me with this please
goldfiish [28.3K]

Answer:

12

Step-by-step explanation:

You need to use PEMDAS

No Parenthesis

4^2 is 16, since 4 * 4 = 16

Now the equation is 24 - 16 + 2*2

2 * 2 = 4

24 - 16 + 4

24 - 16 = 8

8 + 4 = 12

Hope this helps

Simplify 0.75 : 2 5/16​
icang [17]

To start this is a ratio, and the goal is to get at least 1 to be a whole number so first lets get the number below 1 to 1.

0.75 : 2 5/16 ---> (x1.3333 on both sides) ---> 1 : 3 1/12.

Next, if needed for your answer, lets get the other number to be a whole number as well. We can do this my multiplying both sides by 12 since the fraction on 3 1/12 is 1/12.

1 : 3 1/12 --> (x12 on both sides) ---> 12 : 37

Your final answer will either be 1 : 3 1/12 or 12 : 37, depending on the formatting expected for your homework assignment.

In the supermarket, there is a scale that measures the weight of fruit and vegetables. The needle is 24 cm long and it rotated 9
Mumz [18]
We find the length of the arc followed by the needle. For this, we first need to convert the subtended angle to radians:
96/∅ = 180/π
∅ = 1.68 rad
S = r∅
S = 24 x 1.68
Distance covered by needle = 40.32 cm
