Answer: What shape is this? A triangle?
Step-by-step explanation:
Assuming that this is a triangle with no 90 degree angles:
-5x + 32 = 180
-32 = -32
---------------------
-5x = 148
----- = -----
-5 = -5
x = -29.6
Assuming that this is a triangle with 90 degree angles:
-5x + 32 = 90
-32 = -32
----------------------
-5x = 58
----- = -----
-5 = -5
x = 11.6
For both of these you would get a decimal so you need to provide an image or more information to your question

(2x+3y=23)(3x+4y=15)using ellimination method.
Answer:
x = -47, y = 39
Step-by-step explanation:
2x+3y=23 →equation 1
3x+4y=15 →equation 2
by elimination method,
(2x+3y=23) × 4
(3x+4y=15) × 3
8x + 12y = 92
(-) (-) (-)
9x + 12y = 45
---------------------
-1x + 0 = 47
-x = 47
x = -47
substitute x=-47 in equation 1
2(-47) + 3y = 23
-94 + 3y = 23
3y = 23 + 94
3y = 117
y = 117/3
y = 39
therefore, x = -47 and y = 39
hope you understood ❤❤❤

Find a third degree polynomial with rational coefficients that has the given numbers as given roots
4 and 3 - [tex]\sqrt{2}[/tex]
Answer:
[tex]x^3-10x^2+31x-28[/tex]
Step-by-step explanation:
Since we are looking for a polynomial with RATIONAL coefficients, then we know that if [tex]3-\sqrt{2}[/tex] is a root, then its conjugate [tex]3+\sqrt{2}[/tex] must also be a root
Therefore, we build the polynomial using binomial factors with the given roots as shown below:
[tex](x-4)*(x-3+\sqrt{2} )*(x-3-\sqrt{2} )= (x-4)((x-3)^2-2)=\\=(x-4)*(x^2-6x+9-2) =(x-4)*(x^2-6x+7)=\\=x^3-10x^2+31x-28[/tex]

The lawful speeds S on an interstate highway satisfy |S-60| <= 17.5. Find the maximum and minimum speed limits by solving the absolute value equation |S-60| = 17.5
Answer:
Step-by-step explanation:
Given the expression of the speed satisfying the equation |S-60|≤17.5
The inequality expression will return both a negative and positive value.
For the positive value of the function;
S-60 ≤17.5
S ≤17.5+60
S ≤ 77.5
For the negative value of the function;
-(S-60) ≤17.5
-S+60 ≤17.5
-S ≤17.5 -60
-S ≤ -42.5
multiply through by -1
S≥42.5
Hence the minimum speed limit is S≥42.5 while the maximum is S ≤ 77.5

A bat can fly 84 feet in four seconds. A dove can
fly 35 feet in two seconds. Which can fly faster and by
how much?
Answer:
A bat
Step-by-step explanation:
Answer:
The bat flies faster by 7 feet
Step-by-step explanation:
first, you need to find some common ground. 84 and 4 can both be divided by two 84/2=42 so now we know that:
-The bat flies 42 feet in two seconds
-The dove flies 35 feet in two seconds
So we know that the bad flies faster because the number is greater, but by how much?
To find this just subtract 35 from 42 to get 7.
So to summarize
The bat flies faster by 7 feet

Find the standardized test statistic t for a sample with n = 15, = 10 , s = 0.8, and if Round your answer to three decimal places.
Complete question :
Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.
Answer:
−2.420614
Step-by-step explanation:
Given that:
Given that:
n = 10
s = 0.8
X = 15
μ = 15.9
Using the relation :
(x - μ) / (s/√n)
(10 - 10.5) / (0.8/√15)
-0.9 / 0.2065591
= −2.420614
Hence, the standardized test statistic = −2.420614
You are a researcher studying the lifespan of a certain species of bacteria. From a previous study, it was found that the standard deviation was 5.6 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.45 hours at a 98% level of confidence. What sample size should you gather to achieve a 0.45 hour margin of error?
Answer:
The sample size is [tex]n = 841 [/tex]
Step-by-step explanation:
From the question we are that
The standard deviation is [tex]\sigma = 5.6 \ hours[/tex]
The margin of error is [tex]E = 0.45[/tex]
From the question we are told the confidence level is 98% , hence the level of significance is
[tex]\alpha = (100 - 98) \%[/tex]
=> [tex]\alpha = 0.02[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.33[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [2.33 } * 5.6}{0.45} ] ^2[/tex]
=> [tex]n = 841 [/tex]

Find the equation of a line (in y = mx + b form) through the point (-2,5) with an angle of
inclination of 45°.
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope - intercept form is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope m;
m = tan theta
m = tan 45
m = 1
Get the intercept c;
Substitute m = 1 and (-2, 5) into the equation y = mx+c and get c;
5 = 1(-2)+c
5 = -2+c
c = 5+2
c = 7
Get the required equation;
y = 1(x)+ 7
y = x + 7
Hence the equation of the line is y = x+7
