4 0
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions

8) The sides of a flower garden are shown in the diagram below. What is the perimeter of the flower garden? 4m 2 m​
jeka94

Answer:

18.28 m

Step-by-step explanation:

Given the flower garden in the question :

The shape is composite and can be divided into 2 semicirles and rectangle

The perimeter of a semicircle is the Circumference of the semicircle = πr

Hence, 2 semicirles = 2πr

Radius of semicircle = 2/2 = 1

Perimeter = 2 * 3.14 * 1² = 2 * 3.14 * 1 = 6.28 m

The perimeter of rectangle; length and width are 6m and 2 m respectively :

Perimeter of rectangle = 2(l + w) = 2(4+2) = 2(6) = 12m

Tve perimeter of garden = 6.28 + 12 = 18.28 m

oksian1 [2.3K]

Answer:

D

Step-by-step explanation:

he picked 11 tomatoes per plant, 55 ÷ 5 = 11 so all answers that dont include an 11 are incorrect, A and C are wrong

because the tomato plants are listed before the tomatoes picked in the ratio that means that the number of plants has to be first, and the number of tomatoes has to be second. that means the answer is D, 1 plant: 11 tomatoes

The triangles are similar.

Their dimensions are proportional.

Finding scale factor :

  • DC/AE
  • 10/20
  • 1/2

Finding h :

  • h + h/2 = 36
  • 3h/2 = 36
  • 3h = 72
  • <u>h = 24 cm</u>
