Option A. The set of side measurement that can be used to form a triangle is given as A. 13, 19, 7
What is a triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices. In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.
How to get the measurement that can produce a triangle.

a + c > b = 13 + 7 > 19
b + c > a = 7 + 9 > 13

Zion Sun Chairs manufactures 3,575 beach chairs each month. Determine the minimum sales price Zion Sun Chairs must sell each chair for to earn a monthly profit of $55,000, if the total monthly fixed costs are $17,363.50 and the variable cost per chair is $52.17. $72.41 $70.80 $25.38 $20.24
Answer:
A) $72.41------------------------------
Find the total cost to produce 3575 chairs. It includes the fixed costs as well as the variable cost per chair.
17363.50 + 3575*52.17 = 203871.25Add the profit we want to have
203871.25 + 55000 = 258871.25This is the minimum amount to be made from sale.
Find minimum sales price per chair:

What is the slope of the line created by this equation?
Round your answer out to the two nearest decimal places
6x + 9y = 1
Answer:
-0.67
Step-by-step explanation:
What is the slope of the line created by this equation? Round your answer out to the two nearest decimal places. 6x + 9y = 1
_____________________________________________
Slope intercept form solves for y:
y = mx + b when m = slope and b = y-intercept
First, solve for y:
6x + 9y = 1
subtract 6x from both sides:
6x + 9y - 6x = 1 - 6x
9y = 1 - 6x
divide both sides by 9:
9y/9 = (1 - 6x)/9
y = 1/9 - 6/9x
reduce right side:
y = 1/9 - 2/3x
rearrange right side:
y = - 2/3x + 1/9
Back to the equation: y = mx + b when m = slope and b = y-intercept
your slope is -2/3
in decimal form, rounded to two digits: -0.67

cos(76) —>
sin(66)—>
sin(53)—>
cos(49)—>
Answer:
see explanation
Step-by-step explanation:
using the cofunction identities
cos x = sin(90 - x)
sin x = cos(90 - x)
then
cos76° = sin(90 - 76)° = sin14°
sin66° = cos(90 - 66)° = cos24°
sin53° = cos(90 - 53)° = cos37°
cos49° = sin(90 - 49)° = sin41°
The Matched values are
cos(76) —> sin (14)
sin(66)—> cos (24)
sin(53)—> cos (37)
cos(49)—> sin (41)
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
For complementary angle,
a+ b= 90
So, sin (14)
= cos (90 - 76)
= cos 76
and, cos (37)
=sin (90 - 53)
= sin (53)
and, sin (49)
= cos (90- 41)
= cos 41
and, cos (66)
= sin (90 - 24)
= sin 24
Then, the Matched values are
cos(76) —> sin (14)
sin(66)—> cos (24)
sin(53)—> cos (37)

for sample size n, the margin of error is 3. how many more samples do we need to make the margin of error 0.3?
We will need 100 more samples to make the margin error of 0.3 .
What are sample errors?When the statistical characteristics of a population are estimated from a subset, or sample, of that population, sampling errors are made in statistics. Statistics of the sample (commonly referred to as estimators), such as means and quartiles, usually diverge from those of the total population because the sample does not include all individuals of the population (known as parameters). The sampling error is defined as the discrepancy between the sample statistic and the population parameter. For example, if one measures the height of a thousand individuals from a population of one million, the average height of the thousand is typically not the same as the average height of all one million persons in the country.acc to our question-

When Lily left her house in the morning, her cell phone battery was partially charged. The charge remaining in Lily's battery, as a percentage, can be modeled by the equation B=-4t+52,B=−4t+52, where t is the number of hours since Lily left her house. What is the x-intercept of the equation and what is its interpretation in the context of the problem?
The x-intercept of the equation is 13 and its interpretation in the context of the problem is the number of time in hours for which Lily left her house.
What is x-intercept?In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).
Next, we would determine the number of time for which Lily has left her house since in the morning by substituting the value of B with zero (0) as follows:
B = -4t + 52
0 = -4t + 52
4t = 52

Prior to cellular radio, mobile radio and telephone services required
a. high-power transmitter/receiver.
A radio transmitter, also known as a transmitter, is an electronic device that generates radio waves using an antenna in electronics and telecommunications. The transmitter generates alternating current with a radio frequency that is applied to the antenna. The antenna emits radio waves when it is excited by this alternating current.
Typically, the term transmitter refers to equipment that generates radio waves for communication or radiolocation, such as radar and navigational transmitters. Even though they frequently use similar circuits, radio wave generators for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not typically referred to as transmitters.
Transmitters are required components of all radio-communication devices, including radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, and Bluetooth-enabled devices.

suppose a sample of a certain substance decayed to 67.8% of its original amount after 300 days. (round your answers to two decimal places.) (a) what is the half-life (in days) of this substance? days
The half-life of this sample is 535.1 days.
Half-life is defined as the time it will took a substance to reduce to half of its initial amount. The half-life of a substance is determined with respect to the rate of the reaction. It can be calculated using the formula below.
N(t) = N₀(1/2)^(t/T)
where N(t) = amount of substance remaining after time t
N₀ = initial amount of substance
t = time
T = half-life
If a sample of a certain substance decayed to 67.8% of its original amount after 300 days, then N(300) = 0.678N₀.
Plug in the given values to the equation.
N(t) = N₀(1/2)^(t/T)
0.678N₀ = N₀(1/2)^(300/T)
