Answer:

14^2+48^2=2500 sqrt2500= 50 c=50

Step-by-step explanation:

The length of c using the Pythagorean theorem is 50 units.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given triangle is ABC which is right angle triangle

AB=c

BC=14 and AC=48

We have to find the value of c

By Pythagoras theorem, in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

AB²=AC²+BC²

c²=48²+14²

c²=2304+196

c²=2500

Take square root on both sides

c=√2500

c=50

Hence, the length of c using the Pythagorean theorem is 50 units.

Answer: $11836.8

Step-by-step explanation:

Given. That :

Amount invested = $5000

Interest rate = 9% = 0.09

Period = 10 years, compounded annually

Using the compound interest formula :

A = p(1 + r/n)^nt

A = final amount

P = principal or invested amount

r = rate of interest

n = number of times interest Is applied per period

t = period

A = 5000(1 + 0.09/1)^(1*10)

A = 5000(1.09)^10

A = 5000 * 2.36736367459211723401

A = 11836.81837296058617005

= $11836.8

Answer:

[tex]y=-\frac{2}{3}x -5[/tex]

Step-by-step explanation:

Slope-intercept form:

[tex]y=mx+b\\\\y=(slope)x+(y-intercept)[/tex]

When two lines are parallel, their slopes are the same. Take the slope from the given equation and insert into the new:

[tex]y=-\frac{2}{3} x+b[/tex]

Now find the y-intercept. For this, insert the given coordinate points and the slope into the equation to solve for b:

[tex](-6_{x},-1_{y})\\\\-1=-\frac{2}{3} (-6)+b[/tex]

Simplify multiplication using the rule [tex]\frac{a}{b} *c=\frac{ac}{b}[/tex] :

[tex]-1=-\frac{2(-6)}{3} +b\\\\-1=-\frac{-12}{3} +b\\\\-1=\frac{12}{3} +b\\\\-1=4+b[/tex]

Use inverse operations to isolate the variable. Subtract 4 from both sides:

Answer:

[tex]\displaystyle S_{27}=675[/tex]

Step-by-step explanation:

The sum of N consecutive natural numbers is given by:

[tex]\displaystyle S_N=\frac{N}{2}(F+L)[/tex]

We need to find the sum of the natural numbers between 12 to 38.

To calculate the required sum we have F=12, L=38, but we don't have the value of N.

From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.

Substituting in the formula:

[tex]\displaystyle S_{27}=\frac{27}{2}(12+38)[/tex]

[tex]\displaystyle S_{27}=\frac{27}{2}(50)[/tex]

Answer:

The graph is a straight line.

The line does not pass through the origin.

The y-intercept of the line is 2.

Step-by-step explanation:

I know that it's a straight line because the equation is written in this format; y=mx+b (this is a linear equation meaning that it must be a straight line).  In that equation, m is our slope and b is our y-intercept with this information. I know that the y-intercept is 2 since this equation is this y= –12x+2 (the 2 replaced the b which is our y-intercept). The line does not pass through the origin because its y-intercept is 2 which means it's impossible for the line to pass through the origin. (I hope this makes sense)

The length opposite the angle is the vertical distance from the x-axis on the graph.

Step-by-step explanation:

sin (π/3) = opposite/hypotenuse = opposite/1; The length opposite the angle is the vertical distance from the x-axis on the graph.

Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.

The angle π/3 forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).

Also, the terminal side intersect the circle at (x, y). Thus;

sin (π/3) = opposite/hypotenuse = opposite/1

Thus;

sin (π/3) = opposite

Also, the length opposite the angle is the vertical distance from the x-axis on the graph.

The cost equation has two terms. The constant term (400) is the daily fixed cost of building and equipment. The variable term (175p) represents the cost of producing p phones.

The y-intercept is 400. It is the daily fixed cost of the building and equipment.

Answer:

The y-intercept of the function is 400 which represents the fixed cost for rent and equipment.

i aint never seen two pretty best friends, its always one em gotta be ugly

The slope of the line passing through (-5,3) and (-3,8) is 5/2.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

To find the slope of a line passing through two given points, we use the formula:

m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

where m is the slope and[tex](x_1, y_1) ~and ~(x_2, y_2)[/tex] are the coordinates of the two points.

Plugging in the values given, we get:

[tex]m = \frac{8-3}{-3-(-5)} = \frac{5}{2}$$[/tex]

Therefore,

The slope of the line passing through (-5,3) and (-3,8) is 5/2.

Answer:

║ x - 231 ║ ≤ 459

Step-by-step explanation:

Since we have 228 ft below sea level, this is x' = -228 ft. Also,  we have 690 ft above sea level, this is x" = 690 ft.

Since x is our elevation in feet, x ranges from -228 ≤ x ≤ 690.

To write an absolute value equation for x, we first take the average of the two values for the ranges to obtain the ideal value of x.

So, ideal value = [690 + (-228)]/2 = 462/2 = 231.

We also find the tolerance by taking the difference of both values and dividing by 2. So tolerance = [690 - (-228)]/2 =  [690 + 228)]/2 = 918/2 = 459.

Subtracting 231 from each value of the inequality we have

-228 - 231 ≤ x - 231 ≤ 690 - 231

-459 ≤ x - 231 ≤ 459

Since we have in magnitude the values on the left and right side of the inequality,

So ║ x - 231 ║ ≤ 459

Step-by-step explanation:

1) You find the slope by doing y2-y1/x2-x1 (so 7-(-1)/4-3) then you get the slope of 8

2) then you plug in some points using the slope (I'll use the point (3,-1)) : -1=8(3)+b

3) to find "b", you solve: -1=24+b --> b=-1-24 --> b=-25
