A slice is made perpendicular to the base of a right rectangular pyramid through the vertex as shown below. What is the shape of the cross section? What is the area of the cross section? Explain with complete sentences and proper grammar.
Answer:
Shape: Triangle
Area: 27.5 cm
Step-by-step explanation:
Area formula for a triangle: b(base) x h(height) / 2
so, 5(11)/2 = 55/2= 27.5

Answer:
y = 2/3x +4
Step-by-step explanation:
The y intercept is where the line crosses the y axis
y intercept =4
We can find the slope using two points on the line
(0,4) and (3,6)
m = (y2-y1)/(x2-x1)
= (6-4)/(3-0)
= 2/3
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 2/3x +4
Answer:
y = 2/3x +4
Step-by-step explanation:
let the 2 unknown be a and b
X = 0, Y = 4 -> 4 = 0*a+b -> b = 4
Y =0, X = -6 -> 0 = -6*a + 4 -> a = -4/-6 = 2/3
-> y = 2/3x +4

Which equation shows the same relationship as 42 = 7 / 1/6
Answer:
42 × 1/6 = 7
Step-by-step explanation:
42 multiplied by 1/6 equals 7 since 42 divided by 6 equals 7. This equation is another way to show.
3. A boat is travelling from Point C toward Point D, which is on the shoreline.
The shoreline is represented by the line through Point A and Point B.
Determine whether the path from C to D is perpendicular to the shoreline. A to B.
Justify your answer
A(0,7) B(8,-5) C(-3,-8) D(6,-2)
Answer:
Yes, lines CD & AB are perpendicular
Step-by-step explanation:
AB slope: y = -12/8x + 7
CD slope: y = 6/9x - 6
Once the slopes are simplified:
AB: -3/2
CD: 2/3

Which inequality is true for x = 2?
A) 6x + 20 < 29
B) 7x − 10 < 11
C) 14x + 10 < 37
D) 15x − 18 < 12
Answer: d.
Step-by-step explanation:
Add 18 to both sides.
15x<12+18
Simplify 12+18 to 30.
15x <30
Divide both sides by 15.
x < 15/30
Simplify 30/15 to 2.
x < 2
The inequality 15x − 18 < 12 is true for x = 2
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, are some inequalities, we need to find which of them is true for x = 2
a) 6x + 20 < 29
Solving for x,
6x + 20 < 29
6x > 9
x > 3
b) 7x − 10 < 11
7x < 21
x < 3
c) 14x + 10 < 37
14x > 27
x > 27/14
d) 15x − 18 < 12
15x < 30
x < 2
Hence, the inequality 15x − 18 < 12 is true for x = 2

Which statement about the graph is true?
A.)The number of crackers is the dependent variable, and the number of calories is the independent variable.
B.)The point (42, 6) is on the line.
C.)The number of crackers are graphed on the y-axis, and calories are graphed on the x-axis.
D.)The two variables are the number of crackers and the number of calories.
(Picture not option!just a graph!)
Answer:
D.)The two variables are the number of crackers and the number of calories.
Step-by-step explanation:
The number of crackers is the independent variable, and the number of calories is the dependent variable.
The point (6, 42) is on the line
The number of crackers are graphed on the x-axis, and calories are graphed on the y-axis.

The product of the given numbers is 1.61 × 10⁸.
What is meant by Scientific Notation?Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.
For example, 30,000 can be written as 3 × 10⁴.
Given that,
We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).
The numbers in scientific notation uses exponents.
So we have to use the product rule of exponents here.
(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)
= 16.1 × (10¹ x 10⁶)
We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ
So the product is,
(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)
= 16.1 × 10⁷
= 1.61 × 10⁸
Hence the product in scientific notation is 1.61 × 10⁸.

Part A: Which function(s) could have at most 1 x-intercept? Select all that apply.
Linear
Select a Value
Linear
Quadratic, f(x) = x2 – 5x - 2
Exponential, Linear, y = 2x + 4, f(x) = 3.47
y = 2x + 4, Exponential
f(x) = x2 – 5x – 2, Linear
f(x) = 3.4"
Answer:
y = 2x + 4Step-by-step explanation:
The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.
The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).
Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.
Therefore, the right asnwer is the linear function
The function that could have at most 1 x-intercept is y = 2x + 4.
What is a linear function?It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.
The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points that represent concave down.
Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.
Therefore, it should be a linear function.

Which technique is most appropriate to solve this equation?
x2 + 6= 31
Question 2 options:
quadratic formula
zero product property
square root property
Answer:
Square root property
Step-by-step explanation:
The given equation is :
[tex]x^2+6=31[/tex]
We need to write the most appropriated technique to solve the above equation.
Subtracting both sides of the above equation by 6 such that,
[tex]x^2+6-6=31-6\\\\x^2=25[/tex]
Now taking square root on both sides we get :
[tex]x=\sqrt{25}[/tex]
The square root property is used here, such that the value of x is :
