so what you do is 1.48 x 2.91
Answer:
= 4.39km
Step-by-step explanation:
Camp distance = 1.48Km
Distance travelled afterwards = 2.91km
Mountain Height = total distance travelled
So total distance = 1.48 + 2.91
= 4.39km -----------> final answer

YA is an altitude of AXYZ. What is the length of YA?
O 5√3 units
O 10√3 units
O 15 units
O 20 units
By using Pythagoras theorem we can calculate length of YA and which will come out as, 5√3 units, So Option A is correct.
What is Pythagoras theorem?It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).
Pythagoras theorem,
H² = A² + B²
Given information,
The length of the side YZ is twice of the side AZ,
Given length of side YZ is, 10 unit
Therefore, length of side AZ is, 5 unit
YA is altitude of ΔXYZ,
and ΔAYZ is a right angle triangle so we use Pythagoras theorem
YZ = H = 10
ZA = A = 5
YA = B = ?
100² = 5² + B²
B = 5√3
Hence, the length of side YA is 5√3 unit

Distance between two points:The length of line segment connecting any two points is known as their distance from one another. The length of a line segment connecting the two given coordinates can be used to calculate the distance between the points in coordinate geometry.
What is coordinate geometry used for?The study of geometry utilizing coordinate points is referred to as coordinate geometry (or analytic geometry). The distance between two points can be calculated using coordinate geometry, as can the areas of triangles in the Cartesian plane, the midpoints of lines, and more.
According to the given information:The expression that represents this same shortest distance between P and N in units is found to use the distance between two points to be:
[tex]d=\sqrt{(1-a)^2+(b+2)^2}[/tex]
The distance between two points, (x1,y1) and (x2,y2), is represented by:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
the distance between the points N(a, -2) and P(1,b) is:
[tex]\begin{aligned}&d=\sqrt{(1-a)^2+(b-(-2))^2} \\&d=\sqrt{(1-a)^2+(b+2)^2}\end{aligned}[/tex]

The required solution after three successive iterations is near x = 7/8. Option c is correct.
What is the equation?The equation is the values of two expressions that are equal. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here, we have,
Equation is -2x + 6 = -(2/3)^x + 5. Approximate the solution to the equation above using three iterations of successive approximation.
given that,
-2x + 6 = -(2/3)^x + 5
Arranging the equation
(2/3)^x - 2x + 1 = 0
Since the solution of the equation is when f(x) = 0 at near to x = 0.8
f(x) = (2/3)^x - 2x + 1
First iteration at x =0.8
f(0.8) = 0.123
It will go up more to get exact zero, so
Second iteration at x = 0.9
f(0.9) = -0.106
It seems that zero is near 0.9 so will go down
The third iteration at x = 0.87
f(0.87) = -0.037
Here , solution is much near to x = 0.87 or x =7/8.
Thus, the required solution after three successive iterations is near x = 7/8.

the number of units expected to be sold is uniformly distributed between 300 and 500. if r is a random number between 0 and 1, then the proper expression for sales is
300 + (200)r is the proper expression for sales if the number of units expected to be sold is uniformly distributed between 300 and 500. If r is a random number between 0 and 1.
What is a random number?
a random number is a number chosen by chance -- i.e., randomly, from a set of numbers. All the numbers in a specified distribution have equal probability of being chosen randomly.
Given that r is a random number between 0 and 1. it is uniformly distributed between 300 and 500 will be done by using the formula of 300+200r.
If r = 0, 300+200r will result in the output as 300
If r = 0.5, 300+200r will result in the output as 400
If r= 1, 300+200r will result in the output as 500
Hence ,the proper expression for sales is 300+200r

Write the simplest polynomial function with the given roots 1/2,5, and -2
Answer:
x³-7x²/2-39x/2 + 10Step-by-step explanation:
Given 1/2,5, and -2 as roots of the polynomial, the function in terms of x is expressed as;
P(x) = (x - 1/2)(x - 5)(x+2)
Expand;
(x - 1/2)(x - 5) = x²-5x -x/2 + 5/2
(x - 1/2)(x - 5) = x²-11x/2 + 5/2
P(x) = (x²-11x/2 + 5/2)(x+2) = x³+2x²-11x²/2-22x+5x/2 + 10
P(x) = x³-7x²/2-39x/2 + 10
Hence the required polynomial is x³-7x²/2-39x/2 + 10
Samuel and Savannah purchase stocks in a company. Samuel started with 50 shares and of the stock and buys 10 shares per month. Savannah did not start with any shares, but she buys 25 shares per month. Write an equation that represents the number of months it will take before Savannah and Share the same amount of shares
Answer:
50 + 10m = 25m
Step-by-step explanation:
Given that:
Samuel:
Stating shares = 50 shares plus 10 shares per month
Savanah :
Starting shares = 0 plus 25 shares per month
Let number of months = m
Samuel shares = savanna shares
50 + 10m = 25m
50 = 25m - 10m
50 = 15m
50 / 15 = m
