What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?
Answer:
y = 11x + 76Step-by-step explanation:
The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:
y - y₀ = a(x - x₀)
a = 11, x₀ = -7, y₀ = -1
So:
y - (-1) = 11(x - (-7))
y = 11x + 77 - 1
y = 11x + 76

The sign is negative because the angle is in the 3rd quadrant. This corresponds to ... a. -(4√17)/17
value of sin ( theta ) = -4 (square root of ) 17 / 17
What are Trigonometry Functions ?
Real functions which relate to an angle of a right angled triangle to ratios of two side length.
Given
tan (theta) = 4`
sin(theta) = tan (theta ) / (1 + tan ^ theta)^(1/2)
sin(theta) = 4/(1+(4)^2)^(1/2)
= 4/ (17)^ (1/2)
multiplying and dividing by 17 ^ (1/2), we get
= -4 (17) ^ (1/2) / 17 ( negative since angle is in third quadrant and tan is negative in that quadrant )
option a) -4 (square root of ) 17 / 17

A fair, unbiased coin was flipped 10 times, giving the results shown in the table, where Ttails and heads.
What is the difference between the theoretical and experimental probabilities of getting heads?
please help ill mark you the brainlyest!!!!
Answer: The answer is most likely 0.3
Step-by-step explanation:
The difference between the theoretical and experimental probabilities of getting heads is 0.3.
This question is solved using the concepts of theoretical and experimental probabilities.
Theoretical probability: Calculated without considering previous trials. Experimental probability: Calculated considering previous trials.----------------------------
Theoretical probability:
A fair coin means that it is equally as likely to be heads or tails, so 0.5 theoretical probability of getting heads.
----------------------------
Experimental probability:
Out of 10 trials, 2 resulted in heads, so 2/10 = 0.2 experimental probability of getting heads.
----------------------------
Difference:
0.5 - 0.2 = 0.3
The difference between the theoretical and experimental probabilities of getting heads is 0.3.

The ratio of girls to boys in a sports club is 3: 5
There are 27 girls in the club. How many boys are there?
Answer:
45 boys
Step-by-step explanation:
The 3 part of the ratio refers to the number of girls.
Divide number of girls by 3 to find the value of one part of the ratio
27 ÷ 3 = 9 ← value of 1 part of the ratio, then
5 parts = 5 × 9 = 45 ← number of boys
Answer:
Their are 45 boys.
Step-by-step explanation:
Let's represent Girls by G,and Boys by B
so G = 27 and B = ? and G/B = 3:5 or 3/5
3 = 27
5. B
3B = 135

A triangle has sides with lengths of 10, 15, and 6 feet. Find the perimeter of a similar triangle whose shortest side is 7
Answer:
P = 36 1/6 feet
Step-by-step explanation:
you can create the following proportion:
6 / 7 = 10 / x
cross-multiply:
6x = 70
x = 11 2/3
use the same ratio to write a second proportion to find the last side:
6 / 7 = 15 / x
cross-multiply:
6x = 105
x = 17 1/2
Perimeter = 7 + 11 2/3 + 17 1/2 = 28 7/6 + 7 = 29 1/6 + 7 = 36 1/6 feet

Answer:
Option c = [tex]\sqrt[9]{3}[/tex]
Step-by-step explanation:
One side = 18
Bottom side = 18 (equalateral triangle)
we can use phytagorues theorum:
a = the altitude (unknown)
b= one side (half of the bottom side) = 18/2 = 9
c = hypothenus = 18 (given)
a^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 = 18^2 - 9^2
a^2 = 243
a = [tex]\sqrt{243}[/tex] = [tex]\sqrt{ 3 x 3 x 3 x 3 x 3 }[/tex] = [tex]\sqrt[9]{3}[/tex]

Which of the following shapes is a convex nonagon?
OA)
OB)
OC)
OD)
It is asking for a convex nonagon, not a convex polygon. So in this case we are looking for a shape with 9 straight lines and 9 angles. Which means we can cross A out.
Now we need to look at which nonagon is a convex nonagon which means that we are looking for the shape having only interior angles measuring less than 180°. So this means that B and D can be crossed out.
Thus, the answer is C.

the length of a rectangle is 6 inches less than 4 times the width of the rectangle , write an expression to find the perimeter of the rectangle.
Answer:
x + (4x-6) • 2
Step-by-step explanation:
First, let's start by calling the width of the rectangle x
Because the length is 4 times the width minus 6, the equation for length will be 4x-6
The width and length together will be x + (4x-6)
You then have to times it by 2 to find the whole perimiter.
