Find the area of a rhombus whose side is 5 cm and whose altitude is 8cm. If one of its diagonals is 10 cm long, find the length of the other diagonal.
Answer:
8 cm
Step-by-step explanation:
Given that:
Side = 5cm
Altitude = height = 8cm
Diagonal 1 = 10cm
Diagonal 2 = d
Area of rhombus = base * height = 0.5 * (diagonal 1 * diagonal 2)
5 * 8 = 0.5 * (10 * d)
40 = 5d
Divide both sides by 5
40/5 = 5d / 5
8 = d
Length of other diagonal = 8cm

Find the slope of the line through the points (4, 1) and (6, 3)
I need help ASAP
Answer:
The slope is 1
Step-by-step explanation:
Slope can be found using the expression [tex]\frac{y2-y1}{x2-x1}[/tex]
In this case,
y2 = 3
y1 = 1
x2 = 6
x1 = 4
[tex]\frac{3-1}{6-4}[/tex] = 2/2 = 1
What is the minimum value of the function graphed on the xy-plane above, for
−4 ≤ x ≤ 6?
a) -∞
b) -4
c) -2
d) 1
Answer: -2
Step-by-step explanation:
The lowest point is at (-4,-2) and they are asking for the y value which is -2. C
From the graph, it is taken the the minimum value of the function in the interval is given by -2.
In a graph, the horizontal axis contains the input values, that is, the values of x.The vertical axis contains the output values, that is, the values of y, of the function.
In this problem:
Function is defined between -4 and 6.The minimum value of the vertical axis is -2, thus, the minimum value of the function in the interval is -2.A similar problem is given at https://brainly.com/question/24294701

$8.75
Step-by-step explanation:
Find the equation of a line that passes through points A and B.
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line

The sum of three numbers is 17. The sum of twice the first number, 4 times the second number and 5 times the third number is 56. The difference between 7 times the first number and the second number is 41. Find the three numbers.
Answer:
x=7 y=8 z=2
Step-by-step explanation:
The value of all three numbers will be 7, 8, and 2 for the given condition.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the first number is x, the second is y and the third is z.
The sum of three numbers is 17 ⇒
x + y + x = 17
The sum of twice the first number, 4 times the second number and 5 times the third number is 56 ⇒
2x + 4y + 5z = 56
The difference between 7 times the first number and the second number is 41 ⇒
7x - y = 41 ⇒ y = 7x - 41
By substituting this y into the above equation.
A newly formed equation will be
-40x - 5z = -290
30x + 5z = 220
By solving them x = 7 and z = 2 by that y = 8
Hence all three values will be 7,2 and 8.

Round 243.583 to the nearest tenth *
Answer: 243.6
Step-by-step explanation:
For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.
Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.
