Answer:
H) -6/13
Step-by-step explanation:
To find the slope of the line between a pair of two points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (12,7) and (-14,19) into the formula and simplify like so:
[tex]m = \frac{(19)-(7)}{(-14)-(12)} \\m =\frac{19-7}{-14-12} \\m = \frac{12}{-26} \\m = -\frac{6}{13}[/tex]
So, Option H is correct.

I NEED HELP WITH THIS MATH
Answer:
v = 120
Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360
v = 360/3
v = 120
Answer:
89 = v
Step-by-step explanation:
not completely sure how i got it

Step-by-step explanation:
Find the absolute value of each deviation from the mean
Answer:
Mean Absolute Deviation = 5.3333
Step-by-step explanation:
Xmean = 85
MAD = (85 - 85) + (92 - 85) + (88 - 85) + (80 - 85) + (91 - 85) + (74 - 85) /6
=(0) + (7) + (3) + (5) + (6) + (11) /6
= 32 /6
Mean Absolute Deviation = 5.3333
Evaluate lim
[tex] \frac{3 {x}^{2} + 5x - 1 }{4 {x}^{3} + 2x + 6 } [/tex]
Answer:
[tex]\lim_{x \to 0} =-\frac{1}{6}[/tex]
Step-by-step explanation:
The first step in evaluating a limit should be to plug in the number to see if you get a result
When you plug in 0 to all of the x's in the expression, you are left with the constants -1 on the top and 6 on the bottom of the fraction.
So there's no need to go any further, the limit as x approaches 0 is [tex]-\frac{1}{6}[/tex]
Answer:
-1/6
Step-by-step explanation:
To find the limit as x approaches 0 we can just plug in 0
for the numerator: 3*0+5*0-1 = -1
For the denominator: 4*0+2*0+6= 6
answer is just -1/6 or -.16666666666666666666667

ABC est un triangle rectangle en B.
On donne : AB = 7:BC = a et AC = a +5.
Calcule a
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Function g is a transformation of the parent sine function, f(x) = sin(x). g(x) = 1/3sin(2x - 5) +1 the phase shift of function g is ___.
The phase shift is C/B=5/2
We have given that the equation of the sine wave
[tex]f(x)=sinx\\G(x)=\frac{1}{3} sin(2x-5)+1[/tex]
What is the formula for the sine wave?The formula f(x)=A sin(Bx-C)+D
by comparing the g(x) above formula
Phase shift is C/B
C=5 and B=2
Therefore the phase shift is C/B=5/2

Answer:
2
Step-by-step explanation:
$24 equals 7 pencils, each x dollars worth, and the $10 left over: 24=7x+10.
Solve for x, 24-10=7x
14=7x
$2=x
The cost of each pencil is $2
Answer:
$2
Step-by-step explanation:
→ Work out how much she spent
24 - 10 = 14
→ Divide it by the amount of pencils
14 ÷ 7 = 2
Which expression can be used to find the surface area of the following rectangular prism?
Answer:
option A
Step-by-step explanation:
Here we can see that , the dimensions of the prism ( cuboid ) is 3 × 5 × 6 . If a cuboid has dimensions of l × b × h , then its TSA is ,
⇒ TSA = 2(lb + bh + hl)
⇒ TSA = 2[ (3)(5)+(5)(6)+(6)(3) ]
⇒ TSA = 2 [ 15 + 30 + 18 ]
⇒ TSA = 15 + 15 + 30 + 30 + 18 + 18
Hence the option A is correct .
Hence option (A) is correct.Find the area of the shape shown below.
Answer:
To find the area break up the shapes:
The rectangle is A = bh which is 7*3 which is 21.
Triangle: A = 1/2(bh)
A=1/2(3*7)
A=1/2(21)
A=10.5
Now add up the areas:
21+10.5
=
31.5
The answer is 31.5 units.

9000 dollars Is places in an account with an annual interest rate of 7.75%. How much will be in the account after 18 years, to the nearest cent?
Answer: $21555
Step-by-step explanation:
First, we need to know the interest generated on the money saved. This will be:
= Principal × Rate × Time
= $9000 × 7.75% × 18
= $12555
The amount in the account after 18 years will then be:
= Principal + Interest
= $9000 + $12555
= $21555

2. There are 35 men and 50 women running a race. What is the ratio of the number of female runners to the total number of runners? Answer:____________________________________
Answer:
10 : 17
Step-by-step explanation:
Male runners = 35
Female runners = 50
Total runners = male runners + female runners
= 35 + 50
= 85 runners
What is the ratio of the number of female runners to the total number of runners?
Ratio of the number of female runners to the total number of runners = number of female runners : total runners
= 50 : 85
= 50 / 85
= 10/17
= 10 : 17
Ratio of the number of female runners to the total number of runners = 10 : 17
