Answer:

d. lengths 1 foot,12 inches , 25 inches

Step-by-step explanation:

since the measurements 3,4,5 and ,5,12,13 are used alot in perfect triangles you only have to choose between the last two choices.

then the last choice would be the answer if you use the triangle inequality theorem the side lengths will not equal the same sum.

hope this helps and pls mark brainliest

Answer:

D. Lengths 1 foot, 12 inches, and 25 inches

Step-by-step explanation:

When looking for side lengths of a triangle, there are three factors we need to look into, take a right triangle for example.

There are two small sides and one long side of a right triangle, to answer the question, we need to find two numbers that when added together (two short sides of triangle), equal to less than the long side of the triangle.

A. would be wrong because 3 feet and 4 feet added have a greater amount then 5 feet.

B. would be incorrect because 5 inches and 12 inches (1 foot) equal way more than 13 inches (1 foot and 1 inch).

C. would be wrong because 1 foot (12 inches) and 1 inch equal way more than 1 inch.

D. would be correct because 1 foot (12 inches) and 12 inches equal less than 25 inches.

1 foot + 12 inches = 24 inches

24 inches < 25 inches.

D is the answer.

son4ous [18]

The diameter of the heater=20 in
Diameter of the heater and the overhang=20+4=24 in
the area of the base will therefore be:
A=πr²
A=π(24/2)²
A=144π in²
A~452.39 in²

How to find the equation of this line?

Bad White [126]

Answer:

y = - $\frac{6}{7}$ x - $\frac{10}{7}$

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 = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 4, 2 ) and (x₂, y₂ ) = (3, - 4) ← 2 points on the line

m = $\frac{-4-2}{3+4}$ = - $\frac{6}{7}$ , thus

y = - $\frac{6}{7}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 4, 2 ), then

2 = $\frac{24}{7}$ + c ⇒ c = 2 - $\frac{24}{7}$ = - $\frac{10}{7}$

y = - $\frac{6}{7}$ x - $\frac{10}{7}$ ← equation of line

Indicate in standard form the equation of the line passing through the given points.

Lynna [10]

(-2,2)(5,1)

slope(m) = (1 - 2) / (5 - (-2) = -1 / 7

y = mx + b
slope(m) = -1/7
use either of ur points....(5,1)....x = 5 and y = 1
now sub and find b, the y int
1 = -1/7(5) + b
1 = -5/7 + b
1 + 5/7 = b
7/7 + 5/7 = b
12/7 = b

equation is : y = -1/7x + 12/7....but we need it in standard form...

y = -1/7x + 12/7
1/7x + y = 12/7
x + 7y = 12 <== standard form

Please someone help with that

Maurinko [17]

Answer:

a) -tan(π/4) = -1

b) -1/sin(π/3) = -(2/3)√3

Step-by-step explanation:

The given functions are reciprocals of the primary trig functions:

cot(x) = 1/tan(x)

csc(x) = 1/sin(x)

The tangent function has a period of π, and is equal to the cotangent of the complementary angle.

The given angle is an alias of -π/4, so we can write ...

cot(7π/4) = cot(-π/4) = -cot(π/4) = -tan(π/2 -π/4) = -tan(π/4)

-tan(π/4) = -1

csc(-π/3) = 1/sin(-π/3) = -1/sin(π/3) = -1/(√3/2) = -2/√3

-1/sin(π/3) = -2√3/3
