triangular park ABC has sides 3 m, 5 m, and 6 m. a gardener ravi wants to put a fence all around it and also plant grass inside.

Mariana [72]

Step 1) Check if the given triangle lengths form a right triangle

3^2 + 5^2 = 6^2

9 + 25 = 36

36 = 36

Step 2) Solve for the area of the triangle

Formula: A = 1/2 x base x height

A = 1/2 x 3 x 5

A = 1/2 x 15

A = 7.5 m^2

Step 3) Solve for the perimeter of the triangle

Formula: P = sum of all sides

P = 3 + 5 + 6

P = 14 m

Ravi needs to plant 7.5m^2 of grass and put up a fence that is 14m in total length.

Hope this helps!! :)

Write the equation in exponential form. Assume that all constants are positive and not equal to 1.

algol13

Answer:

1. $16 = 4^2$

2. $2 = {16}^{\frac{1}{4}}$

3. $log_2 y=z$

Step-by-step explanation:

$1.\ log_2 16=4$

Write in exponential form

Using the law of logarithm which says if

$log_b A=x$

then

$A = b^x$

By comparison;

A = 16; b = 2 and x = 4

The expression $log_2 16=4$ becomes

$16 = 4^2$

$2.\ log_{16} 2=\frac{1}{4}$

Write in exponential form

Applying the same law as used in (1) above;

A = 2; b = 16 and $x = \frac{1}{4}$

The expression $log_{16} 2=\frac{1}{4}$ becomes

$2 = {16}^{\frac{1}{4}}$

$3.\ 2^z=y$

Write in logarithm form

Using the law of logarithm which says if

$b^x =A$

then

$log_b A=x$

By comparison;

b = 2; x = z and A = y

The expression $2^z=y$ becomes

$log_2 y=z$
