the formula for calculating speed is DISTANCE divided by TIME equals SPEED (d/t=s). This is called an object's?

Answer:

36.8 ft^2

Step-by-step explanation:

The surface is consisted of 2 triangles and 3 rectangles. The two triangles are the same the Area together = 2.2*1.5 = 3.3 ft^2, then the 3 rectangles are 2.2 X 5, 1.5 X 5 and 3 X 5, so to add them together to get the surface area so SA = 3.3 + 2.2*5 + 1.5*5 + 3 *5 = 36.8 ft^2.

Answer:

C (H. x=3)

Step-by-step explanation:

It wants a line where both sides are equal. Since the parabola is opening upward, it has to be an x= equation. That rules out F and J. Next you count out the points to the vertex on the x axis, which seems to be 3. This means that the line is x=3, or H(c)

Answer:

C

Step-by-step explanation:

The number of people who have heard a rumor is modeled by the logistic function:

[tex]\displaystyle f(x)=\frac{260}{1+23e^{-0.06x}}[/tex]

And we want how many days has passed since the rate at which the rumor spread began to decrease.

First, the numerator tells us that the total number of people who will have heard the rumor by the end is 260.

Recall that the point of maximum growth is always half of the maximum capacity.

In this case, that point will be 260/2 = 130.

For a logistic function, the rate of all values to the left of the halfway point is increasing, (i.e. concave up), while the rate of all values to the right is decreasing (i.e. concave down). Therefore, we can solve for x when f(x) = 130:

[tex]\displaystyle 130=\frac{260}{1+23e^{-0.06x}}[/tex]

Cross-multiply:

[tex]130(1+23e^{-0.06x}})=260[/tex]

Distribute:

[tex]130+2990e^{-0.06x}=260[/tex]

Solving for x:

[tex]2990e^{-0.06x}=130[/tex]

Therefore:

[tex]\displaystyle e^{-0.06x}=\frac{130}{2990}=\frac{1}{23}[/tex]

Taking the natural log of both sides:

[tex]\displaystyle -0.06x=\ln\Big(\frac{1}{23}\Big)[/tex]

Therefore:

[tex]\displaystyle x=\frac{\ln(1/23)}{-0.06}\approx52.3[/tex]

After about 52.3 days, the rate at which the rumor started spreading will begin to decrease.

Answer: f = 100

Step 1.

We'll need to expand 3(f - 91) by multiplying a term and an expression. The following product distributive property will be used: A(B + C) = AB + AC.

In the example, the expression will consist of 2 terms.

First term: 3 and f.

Second term: 3 and -91

Rewrite 3(f - 91) like this.

3f - 3 × 91

Step 2.

Multiply 3 by 91.

3 × 91 = 273

Hence, the answer is 100.

====================================================

Explanation:

To find the volume of the current prism, we multiply length width and height to get 6*12*15 = 1080

Take 1/3 of this to get (1/3)*1080 = 360

To find three different prisms where they have a volume of 360, we just need to think of ways to multiply to 360 using 3 numbers.

Here are some possibilities:

There are other possibilities as well, but you only need to pick three from that list. Or you can come up with other combos as well as long as the three numbers multiply to 360.

If we go with the first three rows for prisms 1, 2, and 3 in that exact order, then

Answer:

13.5 cm

Step-by-step explanation:

The altitude of the base of the isosceles triangle bisects the vertex angle, <T, and also bisects the base, NS.

Therefore, NS is divide into two, 15 cm each.

This means we now have two right triangles from the isosceles triangle with the following:

Reference angle = 42°

Opposite = altitude = h

Adjacent = 15 cm

To find h, apply trigonometric function, TOA:

Tan 42 = Opp/Adj

Tan 42 = h/15

15 * Tan 42 = h

h = 13.5060607 ≈ 13.5 cm (nearest tenth)

Answer:

y = -2x

Step-by-step explanation:

Equation in slope-intercept form is y = mx + b.

m = slope = ∆y/∆x

Using any two points on the line, say (0, 0) and (-20, 40),

Slope (m) = (40 - 0) / (-20 - 0) = 40/-20

Slope (m) = -2

b = y-intercept = the value of y when x = 0.

b = 0

To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b

Thus:

y = -2x + 0

y = -2x
