What Is -0.75-(-2/50)+0.4(-3/4)? Explain and answer the question please

1 answer:

3 0

The answer is -1.01
I first changed the signs of the ones i could. So <span>-0.75+(2/50)+0.4(-3/4)
Then i multiplied the 0.4*-3/4 which equals -0.3
So you are left with </span><span>-0.75+(2/50)-0.3
2/50 is equal to 0.04 so now it is </span> -0.75+0.04-0.3 and the rest is simple math. Which equals -1.01

Determine whether the function f(x)=4x^3 is even or odd

slega [8]

Answer:

Step-by-step explanation:

Answer:

odd function

Explanation:

To determine if a function f(x) is even/odd consider the following.

• If f(x) = f( -x) , then f(x) is even

Even functions are symmetrical about the y-axis.

• If - f(x) = f(-x) , then f(x) is odd

Odd functions have symmetry about the origin.

Test for even function

f(−x)=4(−x)3=−4x3≠f(x)

Since f(x) ≠ f( -x) , then f(x) is not even

Test for odd function

−f(x)=−(4x3)=−4x3=f(−x)

Since - f(x) = f( -x) , then f(x) is odd

Is each line parallel, perpendicular, or neither parallel or perpendicular to a line whose slops is -3/4?

Ymorist [56]

Answer:

Line M is neither.

Line N is perpendicular.

Line P is neither.

Line Q is parallel.

Step-by-step explanation:

Parallel lines are lines whose slope are the same. Line q is the exact same slope. It is parallel.

Perpendicular lines are lines whose slopes are the negative reciprocal of each other $\frac{a}{b}$ , $-\frac{b}{a}$ . Line n is 4/3 and is perpendicular.

Line m and p are neither.

Pls help this packet is driving me crazy!!

AleksAgata [21]

Proportion A
The first thing you should know in this case is what the rate of change means.
The rate of change in a linear equation is given by the slope of the line.
For a linear equation, the rate of change is constant.
So we have to:
y = 9x
The slope is:
m = 9
Proportion B
The slope of the line will be:
m = (y2-y1) / (x2-x1)
Substituting values:
m = (57.5-34.5) / (5-3)
m = 11.5
Answer:
The rate of change in proportion A is 2.5 less than in proportion B.

All of the quadrilaterals in the shape below are squares. Find the area of the shaded region

Mnenie [13.5K]

To find area of square one :-

Given :

side = 9 (unit)

To find :

Area of square

We know :

Area of square = side²

Therefore:-

→Area of square = 9²

→Area of square = 9 × 9

→Area of square = 81 (unit)²

To find area of square two :-

Given :

side = 11 (unit)

To find :

Area of square

We know :

Area of square = side²

Therefore:-

→Area of square = 11²

→Area of square = 11 × 11

→Area of square = 121 (unit)²

Now it's clearly visible that the whole figure is also. a square .

Therefore AE = CP

Which means area of square three = 81 (unit)²

Now area of shaded figure :-

Area of square one + Area of square two + Area of square three
81 + 81 + 121
283 (unit)²
