#1
a²x² - b²y² = (ax + by)(ax - by)
Since (4x - 3y) is one of the factors, we have:
a = 4, b = ± 3The value of a² + b² is:
4² + (±3)² = 16 + 9 = 25#2
x² + 19x + c, has a factor of (x + 7).
It means the equation:
x² + 19x + c = 0 has one root of x₁ = -7.Sum of the roots:
x₂ + (- 7) = -19/1 x₂ = -19 + 7x₂ = -12Product of the roots:
x₂*(-7) = c-12*(-7) = cc = 84can you guys help me

what is the surface area of the tent?
Answer:
Area of 1 Right angle triangle= 1/2* 3*4= 6
Area of both triangle= 6*2= 12
Area of rectangle= 8*5= 40
Area of Both rectangles= 40*2= 80
Total surface area= (12*2)+ 80= 24+80= 104

show all work. what is the measure in degrees of angle A?
Answer:
∠ A = 62°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
116° is an exterior angle of the triangle, then
3x - 13 + 2x + 4 = 116
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Then
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°

Given the first term and the common ratio of a geometric sequence find the seventh term of the sequence. a1=2 and r=6
Answer:
93312
Step-by-step explanation:
We can use the geometric sequence formula
a= a1(r)^n-1
Substitute:
a=2(6)n^1
a=2 *6^n* 1/6
a=6^n*1/3
Substitute "7" for n:
a(7)=6^(7)*1/3
a(7)=93,312
The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a function that models the panda population since 2014.
(exponential growth & decay)
Given:
Giant panda population in 2014 = 1864
The giant panda population in China is increasing at a rate of 1.5% each year.
To find:
The function that models the panda population since 2014.
Solution:
Since population of giant panda is increasing, therefore the function is the exponential growth model.
The general exponential growth model is:
[tex]P(t)=P_0(1+r)^t[/tex]
Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.
Putting [tex]P_0=1864,r=0.015[/tex], we get
[tex]P(t)=1864(1+0.015)^t[/tex]
[tex]P(t)=1864(1.015)^t[/tex]
Where, t is the number of years since 2014.
Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].

A density graph for all the possible heights between 0 inches and 40 inches is
rectangular. What is the height of the rectangle in this density graph?
A. 0.04
B. 0.025
C. 0.02
D. 0.0125
0.02 is the height of the rectangle in this density graph. Therefore, option C is correct.
What is density graph?A density plot illustrates how data are distributed over a continuous range or period of time. This graph is a variation of a histogram that smoothes out noise by using kernel smoothing to plot values, resulting in smoother distributions. A Density Plot's peaks aid in showing where values are concentrated throughout the interval.
Because they are unaffected by the number of bins used, density plots have an advantage over histograms in that they are better at determining the shape of the distribution (each bar used in a typical histogram). As opposed to a 20-bin Histogram, a histogram with only 4 bins would not produce a sufficiently distinguishable shape of distribution. This is not a problem, though, with density plots.
Let height be the X
X~U(0,50)
Height of the uniform distribution = 1/(50-0)
= 0.02
Thus, 0.02 is the height of the rectangle in this density graph.

The probability of it raining today is 30%. What is the probability that it will NOT rain? (answer must be in percent form)
Answer:
70%
Step-by-step explanation:
An easy way to figure this out is like this: Percentage is out of 100 so that would mean 30% is equal to 30/100. Basically, all you need to do is subtract 100-30 and convert to a percent (just add the percent sign). Boom! 70% is your answer!!!!!!! :)
