Answer:

The value of the expression for b=-2 is -9.

Step-by-step explanation:

Consider the provided expression.

$|-4b-8|+|-1-b^3|+2b^3$

We need to solve the expression for b=-2

Substitute the value of b in the provided expression.

$|-4(-2)-8|+|-1-(-2)^3|+2(-2)^3$

$|8-8|+|-1-(-8)|+2(-8)$

$|0|+|-1+8|-16$

$|0|+|7|-16$

$7-16$

$-9$

Hence, the value of the expression for b=-2 is -9.

Use the triangle below to write the given ratios. • sin(P) = tan(T) = cos(T) =

Sati [7]

Answer:

Explaining:

The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle.

In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.

Find the area of the figure shown. Round to the nearest tenth if necessary.

kompoz [17]

Answer:

25.5in²

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = (1/2) x (sum of the lengths of the parallel sides) x height

1/2 x (6 + 11) x 3 = 25.5 in²

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:

With given side lengths a triangle could not be created.

Step-by-step explanation:

Given:

First side length = 7.7 cm

Second side length = 4.0 cm

Third side length = 1.7 cm

We need find whether this could be the side length of the triangle.

Solution:

Now we know that;

By Triangle In equality property which states that;

"Sum of the two side length of the triangle must be greater than third side."

It should fulfill all three conditions;

So we will find the same.

Condition 1:

First Side + Second Side > Third side

$7.7+4.0>1.7\\\\11.7>1.7$

Hence This condition is true.

Condition 2:

Second side + Third Side > First side

$4.0+1.7>7.7\\\\5.7>7.7$

Hence This condition is False.

Condition 3:

First side + Third Side > Second side

$7.7+1.7>4.0\\\\9.4>4.0$

Hence This condition is true.

Since One of the condition is false hence With given side lengths a triangle could not be created.
