Answer:

48

Step-by-step explanation:

Given,

x = - 1

y = 2

To find : The value of 3x - 4 ⋅ xy² ?

Substitute the given values of x and y in the expression 3x - 4 ⋅ xy².

3x - 4 ⋅ xy²

= 3 ( - 1 ) - 4 ⋅ ( - 1 ) ( 2 )²

= - 3 - 4 ⋅ - 1 ( 4 )

= - 12 ⋅ - 4

= 48

Note : -

When a negative number gets multiplied with a negative, the resulted number is a positive number.

The value of f is 348 pounds.

Given

At a big cat reserve, a male Bengal tiger weighs more than a female Bengal tiger.

The male tiger weighs 445 pounds.

The difference in the weight of the tigers is 97 pounds.

<h3>Difference;</h3>

The meaning of DIFFERENCE is the quality or state of being dissimilar or different.

The zookeeper created the bar diagram and the equation below is given as:

\rm 445=f+97

On solving the equation the value of f is;

\rm 445=f+97\\\\f = 445-97\\\\f= 348

Hence, the value of f is 348 pounds.

Need help please! A=?
zubka84 [21]

Answer:

  m∠A ≈ 103°

Step-by-step explanation:

Enough information is shown for us to be able to use the Law of Sines to find the angle. That tells us ...

  sin(A)/a = sin(C)/c

  A = arcsin(a/c·sin(C)) = arcsin(26/6·sin(13°)) = arcsin(0.974788)

  A = 77.1° or 102.9°

The claim is that the figure is drawn to scale, so we can assume that A is an obtuse angle:

  m∠A ≈ 103°

__

<em>Additional comment</em>

The sum of angles A and B must be 180° -13° = 167°. Since angle A is the largest, it must be more than half this value, or more than 83.5°. That means, we must choose the obtuse angle for A, rather than the acute angle.
