Please help I am horrible at math! Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 minutes Ye is 2 miles from home. Which equation models his distance from home y, in terms of minutes, x?
A)y=−0.2x+ 5
B)y=11/7x-27/7
C)y = 11 7 x − 27 7
D) y= 5x− 0.2 y=0.2x

Answer: #2. sin x (sin x + 1) = 0

sin x = 0 or sin x + 1 = 0

sin x = 0 or sin x = -1

Step-by-step explanation:

the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given a equation (1/2)- sin x = 1

Simplifying the given expression

=>  (1/2)- sin x = 1

subtract 1/2 on both sides

=> -sin x = 1/2

=> sin x = -1/2

=> x = 210° and 330°

For all x = 0 to 360°

Answer:

BRAINLIEST PLZZZZ

Step-by-step explanation:

Also given that (x+1) is factor of given polynomial p(x).

Need to determine value of constant c.

We will be solving above problem using factor theorem.

Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.

As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .

According to factor theorem p(-1) = 0

On substituting x = -1 , in given expression of p(x) we get

Hence value of c in the given polynomial is 1

Answer:

c = - 3

Step-by-step explanation:

[tex] \because [/tex] (x+1) is a factor of the polymonial [tex] p(x)=5x^4+7x^3-2x^2-3x+c[/tex]

Let (x + 1) =0[tex] \implies [/tex] x = - 1

[tex] \therefore [/tex] at x = - 1, p(x) =0.

[tex]p(x)=5x^4+7x^3-2x^2-3x+c \\ \\ 0 = 5( { - 1})^{4} + 7( { - 1})^{3} - 2( { - 1})^{2} - 3( - 1) + c \\ \\ 0 = 5 \times 1 + 7( - 1) - 2 \times 1 + 3 + c \\ \\ 0 = 5 - 7 - 2 + 3 + c \\ \\ 0 = 7 - 7 + 3 + c \\ \\ 0 = 3 + c \\ \\ c = - 3[/tex]

Answer:

66.4°

Step-by-step explanation:

Let ∠XYZ be x°.

Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.

[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]

To find the value of x°, take the inverse of cosine.

[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]

Thus, ∠XYZ= 66.4°

Answer:

The answer would be (B) y = 1.5x + 8

Step-by-step explanation:

The equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Aaron who is reading a book. After 4 minutes of reading, Aaron was on page 14 of his book and after 8 minutes he was on page 20.

Now -

(x) represents the number of minutes and (y) is the number of pages.

At x = 4, y = 14

At x = 8, y = 20

The slope of the line will be -

m = (20 - 14)/(8 - 4)

m = 6/4

m = 3/2

The general equation can be written as -

y = 3x/2 + c

20 = 3/2 x 8 + c

20 = 12 + c

c = 8

Now, we can write the equation as -

y = 1.5x + 8

Therefore, the equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
