(1.2x10^5)+(2.4x10^4) what is the sum

Answer:

The correct option is;

D. (x - 5)·(x + 2)·(x + 1)

Step-by-step explanation:

The Rational Root theorem is expressed mathematically as follows;

[tex]Possible \ rational \ roots = \dfrac{Factors \ of \ the \ constant \ term}{Factors \ of \ the \ leading \ coefficient}[/tex]

The given polynomial is presented as follows;

x³ - 2·x² - 13·x - 10

A factor of the polynomial = (x + 1)

The factors of the constant term, -10 = -10, -5, -2, -1, 10, 5, 2, and 1

The factors of the leading coefficient, (the coefficient of the variable having the highest degree or power, x³) = 1

Given that (x + 1) is a known factor, the other two factors are either (x + 5) and (x - 2) or (x - 5) and (x + 2)

The option, that combines (x + 1) and the other two factor combination is (x - 5)·(x + 2)·(x + 1)

∴ The solution which meets the condition is (x - 5)·(x + 2)·(x + 1)

We check;

(x - 5)·(x + 2)·(x + 1)  = x³ - 2·x² - 13·x - 10

Answer:

42 reds.

Step-by-step explanation:

There are 72 marbles in the bag.

P(Red) = 1 - Blue = 1 - 5/12 = 7/12

P(red) = 7/12 * 72 = 42

If 1 - 5/12 confuses you, then find the blue first

5/12 * 72 = 5 * 72/12 = 5 * 6 = 30

The rest must be red.

72 - 30 = 42

Answer:

-1.67 is what I got

Step-by-step explanation:

solved it

The value of f(7) is -1.73 for the function  f(x)=3/(x+2)-√x-3.

Two or more expressions with an Equal sign is called as Equation.

A relation is a function if it has only One y-value for each x-value.

The given function is f(x)=3/(x+2)-√x-3

We need to find the value of f(7)

Replace x with 7 in the given function.

f(7)=3/7+2 - √7-3

f(7)=3/11-√4

=3/11-2

=3-22/11

=-19/11

=-1.73

Hence, the value of f(7) is -1.73 for the function  f(x)=3/(x+2)-√x-3.

Answer:

Cat video: exponential function

Dog video: linear function

Step-by-step explanation: I did it until I got it right.

The cat video is a exponential function and dog video is a linear function .

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

An exponential function is a mathematical function of the following form:

f ( x ) = . where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

According to the question

The tables for

Cat video

Time(month)      Views

0                           50

5                           313

10                         1950

15                         12210

20                        76300

So, as we can observe that values of views are increasing rapidly which can only be possible if function is exponential .

Dog video

Time(days)      Views

0                           10

6                          452

12                         889

18                         1330

24                        1770

So, as we can observe that values of views are increasing in constant pace which can  be possible if function is linear .

We can plot graph of both the tables to check for the function nature .

Hence, the cat video is a exponential function and dog video is a linear function .

Answer:

area of trapezoid =1/2 h(s1+s2)=1/2×8(6+10)=4×16

=64 ft²

option C.64ft2 is your answer

Answer:

[tex]\Large \boxed{\sf 64 \ ft^2}[/tex]

Step-by-step explanation:

Area of trapezium/trapezoid formula:

[tex]\displaystyle \frac{(a+b)\times h}{2}[/tex]

Substitute the values and evaluate

[tex]\displaystyle \frac{(6+10)\times 8}{2}=\sf 64[/tex]

The height of the hill is 520 ft

The height of the hill, h the length of the road, L and the ground form a right angled triangle with length of the road as the hypotenuse side and the height of the hill as the opposite side to the angle the road makes with the horizontal, Ф.

Now, from trigonometric ratios,

sinФ = h/L

Making h subject of the formula, we have

h = LsinФ

Since L = 2500 ft and Ф = 12°, thus

h = LsinФ

h = 2500 ft × sin12°

h = 2500 ft × 0.2079

h = 519.78 ft

h ≅ 520 ft to the nearest foot

So, the height of the hill is 520 ft
