kirill [66]

Answer:

35 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 5, thus

A = $\frac{1}{2}$ × 14 × 5 = 7 × 5 = 35 units²

Elly has 2 rectangular gardens. One measures 1809 cm by 2891 cm and the other measures 738 cm by 249 cm. Elly wants to put a fen

Liono4ka [1.6K]

Answer:

She needs 11374 cm to buy

Step-by-step explanation:

* Lets explain how to solve the problem

- The dimensions of the first rectangle is 1809 cm and 2891 cm

- The dimensions of the first rectangle is 738 cm and 249 cm

- Elly wants to put a fence around both

- To find the length of the fence calculate the perimeters of the two

rectangles

- The perimeter of the rectangle = 2(b + h), where b , h are the

dimensions of the rectangle

# First rectangle

∵ The dimensions are 1809 cm and 2891 cm

∵ P = 2(b + h)

∴ P = 2(1809 + 2891) = 2(4700) = 9400 cm

# Second rectangle

∵ The dimensions are 738 cm and 249 cm

∵ P = 2(b + h)

∴ P = 2(738 + 249) = 2(987) = 1974 cm

∵ The length of the fence = the sum of the perimeters of the two

rectangles

∴ The length of the fence = 9400 + 1974 = 11374 cm

* She needs 11374 cm to buy

Find the length of the curve on the given interval x=y^(1/2) from y=0 to y=4

Ulleksa [173]

Here we have to use the following formula

$l=\int\limits^a_b {\sqrt{1+(x')^2} \, dy$

x' is the derivative with respect to y

Given value of x is

$x = y^{1/2}$

Differentiating with respet to y

$x ' = \frac{1}{2y^{1/2}}$

Substituting the value of x' in the formula, we will get

$L=\int\limits^4_0 { \sqrt{1+\frac{1}{4y}}} \, dy$

$L = 4.65$

An account had an initial deposit made and then interest was applied once a year at a fixed rate. The amount of money, in dollar

Cerrena [4.2K]

The equation says
A=p(1+r)^t
A=103(1+0.02)^t
So the interest rate is
0.02*100=2%
