Step-by-step explanation:

you just have to put the given values in place of the variable names and then simply calculate.

(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8

so, B is the right answer.

please remember the correct sequence of operations :

first are brackets.

then exponents.

then multiplications and divisions.

and then (at last) additions and subtractions.

and also please remember : multiplying a negative number with a negative number creates a positive result.

that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.

now you also know the result of -2³, right ?

as this means -2 is multiplied 3 times by itself. what does that do to the sign ?

-2 × -2 = 4 (positive).

but now we have to multiply a third time

4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh  

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh  

15 = ½(10)h  

15 = 5h

Divide both sides by 5 to solve for h:

[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

Step-by-step explanation:

The range for the given scenario is y≥0.

Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.

Part B: Tina said that a possible range for the given function is y > 0.

From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.

Therefore, the range for the given scenario is y≥0.

Step-by-step explanation:

Answer:

94.2cm in 1 hour.

Step-by-step explanation:

In 1 hour, minute hand completes one round means makes a circle.

Radius of the circle(r)=15cm

Circumference of circular clock=2πr

=2×3.14×15=94.2cm

Therefore, the tip of the minute hand moves 94.2cm in 1 hour.

Answer:

The X is equal to 1.75

Step-by-step explanation:

3.5X2.25=7.875

14/7.875=1.75

Answer: x=1.75

Step-by-step explanation:

rearrange the term: 3.5 (2.25 + x) = 14

the new term: 3.5 (x + 2.25) = 14

Combine multiplied terms into a single fraction, then distribute.  

x = 1.75

Answer: 1) 80 - 66 = 14

Answer:

Y = 1/2x + 2

Step-by-step explanation:

First you find (b) or the Y-intercept which is 2 (Y = mx + 2)

Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2

Now you have your answer Y = 1/2x + 2

Answer:To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

Answer:

All Real Numbers

Step-by-step explanation:

First, use the distributive property to expand everything:

8v-6=10v-6-2v

Then, combine like terms:

8v-6=8v-6

Then, subtract 8v from both sides to isolate the variable:

0-6=-6

-6=-6

Any real number you substitute with v will make the equation always true, as -6 always is equal to -6. Therefore, the answer is All Real Numbers.

Answer:

126.5

Step-by-step explanation:

first, break the figure into a triangle and a square (do I have to tell u where)

the square: 11*8=88

the triangle: 11*7=77          77/2= 38.5

88+38.5= 126.5

The solution is, the area of the given figure is : 126.5cm^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

we need to find  the area of the given figure.

so, we have ,

first, break the figure into a triangle and a square

now, we get,

the square:

area= 11*8

       =88

and, we have,

the triangle:

area =1/2* 11*7

       =1/2*77          

       = 77/2

       = 38.5

so, we get,

the area of the given figure is:

88+38.5= 126.5

Hence, The solution is, the area of the given figure is : 126.5cm^2.
