Help me find p.....​
help me find p.....​ - 1

Answers

Answer 1
Answer:

Answer: p = 120 degrees

Step-by-step explanation:

Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.

1. Subtract the known numerical angle

540 - 60 = 480

All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.

2. Evaluate the equation to find the value of p.

4p = 480

p = 120

Find the length of the base of a square pyramid if the volume is 1,024 cubic inches and has a height of 12 inches.

Answers

Hello,

Let 's x the length of the pyramid:
V=x²*h/3
V=1024 and h=12
So x²*12/3=1024
==>x²=1024*3/12
==>x²=256
==>x²=16²
==> x=16 for (x=-16 must be exclude <0)

How do you solve 10(3^x) = 810 ?

Answers

3^x = 810/10
3^x = 81
Since 81 has a perfect fourth power of 3, which is 3*3*3*3 = 3^4 = 81
3^x = 3^4
You can easily remove the similar bases (which is 3) and bring down the exponent.
x = 4
- - To Start, Divide both sides by 10

(10(3^x))/(10) = (810)/(10)

- - Solve For The Exponent:

3^(x) =81

- - Now use log to solve:

log(3x)=log(81)

x*(log(3))=log(81)

x= (log(81))/(log(3))

x=4

Which is smaller 0.9, 75% or 4 fifths?

Answers

In that case, try to bring all numbers into one format.

75% = 0.75

4/5 = 0.8

So, 75% is the smallest whereas 0.9 is largest
Which is smaller 0.9, 75% or 4 fifths?

Answer:

In summary:

- Axis of symmetry: Not determinable from the given information.

- X-intercepts: (-1, 0) and (1.5, 0).

- Y-intercept: Not determinable from the given information.

- Vertex: (-1, 4).

- Interval of decrease: (-∞, -1) and (1.5, ∞).

Step-by-step explanation:

To identify the axis of symmetry, x-intercepts, y-intercept, and vertex of a graph, we need to analyze the given information and graph:

1. Axis of symmetry: The axis of symmetry is a vertical line that divides the graph into two symmetric halves. It is represented by the equation x = h, where h is the x-coordinate of the vertex. Based on the given information, we don't have the equation of the graph or the value of h, so we cannot determine the axis of symmetry.

2. X-intercepts: X-intercepts are the points where the graph intersects the x-axis. These points have a y-coordinate of 0. From the given information, we have the x-intercepts as follows:

- First x-intercept: (-1, 0)

- Second x-intercept: (1.5, 0)

3. Y-intercept: The y-intercept is the point where the graph intersects the y-axis. It has an x-coordinate of 0. From the given information, we don't have the y-intercept, so we cannot determine its value.

4. Vertex: The vertex is the highest or lowest point on the graph. It has an x-coordinate and a y-coordinate. From the given information, we have the vertex as follows:

- Vertex: (-1, 4)

Now, let's determine the interval in which the function is decreasing. To do this, we need to analyze the graph and observe where the graph is sloping downwards or decreasing. From the given information, we can see that the graph is decreasing in the interval (-∞, -1) and in the interval (1.5, ∞). These intervals represent the regions on the x-axis where the function is decreasing.
