Answer:

0.4 second

Step-by-step explanation:

The formula D = st is the formula that can be used to substitute in the values (which is already in the problem).

If the speed is 175 meters a second and the distance is 70 meters, than that means 70 = 175t.

(I substituted 70 for distance, or D, and 175 for speed, or s).

Divide 175 on both sides in order to isolate the variable (t), which is 0.4 second.

The time taken for the hurricane to reach the shore would be 0.4 second.

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

$x^2=4^2+4^2$

$x^2=16+16$

$x^2=32$

We take positive square root to obtain

$x=\sqrt{32}$

$x=4\sqrt{2}$

x=5.66ft

Rounding to the nearest feet we have x=6ft

Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5

The chess club has 16 members and gains a new member every month. the film club has 4 members and gains 4 new members every mont

steposvetlana [31]

For chess club:
y1 = 16 + 1*x where y1 = total number of members after x months .
For film club:
y2 = 4 + 4*x where y2 = total number of members after x months.

y1 = y2 when:
16 + x = 4 + 4x
3x = 12
x = 4 months
Answer: C. 4 months.

Answer:

B. No, the remainder is -50.

General Formulas and Concepts:

Algebra I

Roots are when the polynomial are equal to 0

Algebra II

Synthetic Division

Step-by-step explanation:

Step 1: Define

Function f(x) = x³ - 10x² + 27x - 12

Divisor/Root (x + 1)

Step 2: Synthetic Division

See Attachment.

To determine whether a given root is an actual root, the remainder must equal 0. Since we have a remainder of -50, the given root is not a factor of the polynomial.

Graph the function rule. Tell whether the graph is continuous or discrete. The height h, in inches, of the juice in a 20-oz b

tangare [24]

The x-axis is the amount of juice because it is the independent equation, while the y-axis is the height. The range of the x-axis starts from 0 to the maximum 20 oz. The graph is shown in the attached picture. As shown, the graph is continuous.
