Scalene triangles have 3 sides of different lengths
Isosceles triangles have 2 sides of the same length
Equilateral triangles have 3 sides of the same length

This triangles has a tick mark on 2 sides, meaning that 2 sides are the same length, making this an isosceles triangle

Aaden is 1.75 meters tall. At 11 a.m., he measures the length of a tree's shadow to be 37.65 meters. He stands 32.9 meters away

Ratling [72]

The relationship between Aaden and the tree's height is an illustration of equivalent ratio

The height of the tree is 2.00 meters

At 11 a.m, we have:

$\mathbf{Aaden = 1.75m}$

$\mathbf{Tree\ Shadow = 37.65m}$

$\mathbf{Aaden\ Shadow = 32.9m}$

So, we make use of the following equivalent ratio

$\mathbf{Aaden : Tree = Aaden\ Shadow : Tree\ Shadow}$

This gives

$\mathbf{1.75: Tree = 32.9: 37.65}$

Express as fractions

$\mathbf{\frac{Tree}{1.75} = \frac{37.65}{32.9}}$

Multiply both sides by 1.75

$\mathbf{Tree = \frac{37.65}{32.9} \times 1.75}$

$\mathbf{Tree = 2.00}$

Hence, the height of the tree is 2.00 meters

Monica measures the number of bacteria that are living on her petri dish. Each day, she measures the amount of change in the num

den301095 [7]

Answer:

6554

Step-by-step explanation:

The sequence 2, -8, 32, -128 has a first term (a1) of 2 and a common ratio (r) of -8/2 = -4. The sum of n terms is given by ...

Sn = a1·(r^n -1)/(r -1)

For your sequence, the sum of 7 terms is ...

S7 = 2·((-4)^7 -1)/(-4-1) = 2(-16384/-5) = 6554

The sum of changes after the 7th day is 6554.

#4: Solve the quadratic equation below by completing the square. Select

Snowcat [4.5K]

Answer:

x = - 13, x = - 3

Step-by-step explanation:

Given

x² + 16x = - 39

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(8)x + 64 = - 39 + 64

(x + 8)² = 25 ( take the square root of both sides )

x + 8 = ± $\sqrt{25}$ = ± 5 ( subtract 8 from both sides )

x = - 8 ± 5, thus

x = - 8 - 5 = - 13 or x = - 8 + 5 = - 3
