Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
To find the slope you can use the slope equation:
[tex]slope = \frac{y2 - y1}{x2 - x1}[/tex]
Let's define the terms in the equation:
y2 = 5
y1 = 7
x2 = 4
x1 = 8
Now, let's put these into the equation and solve:
[tex]slope = \frac{5 - 7}{4 - 8} = -\frac{2}{4} = -\frac{1}{2}[/tex]
Therefore, the slope is -1/2.
I hope this helps!!

x-0 1-cos 2x cos 4x
After evaluating the limit we get the answer as 3/5.
Given the expression is : limₓ₋₋₎₀ cos 2x ₋ cos 4x/1-cos2xcos4x
= limₓ₋₋₎₀ cos2x - (2cos²2x ₋ 1)/1-cos2x(2cos²2x - 1)
= limₓ₋₋₎₀ -2cos² + cos2x +1/₋2cos³2x + cos2x + 1
let u =cos2x that is, u → 0
= limu₋₋₎₁ -2u²+u+1/₋2u³+u+1
= limu₋₋₎₁ 2u + 1/2u²+2u+1
= 2+1/2×1² + 2 × 1 +1
= 3/2+2+1
= 3/5
hence we get the value as 3/5.

Which of the following exponential functions has a horizontal asymptote at y = –2 ? f (x) = 2(–x + 2) f (x) = 2(–x – 2) f (x) = –2x + 2 f (x) = –2x – 2
An exponential function with a horizontal asymptote at y = -2 will be of the form:
f(x) = 2^(-x) - 2
Which of the following exponential functions has a horizontal asymptote at y = -2?An exponential equation will have a horizontal asymptote when the exponent, x, has a negative sign. This will cause that as x tends to infinity, the exponential part of the function will tend asymptotically to zero.
Now, if we want to have an horizontal asymptote at y = -2, then we also need to have a constant term equal to -2 which takes weight as x tends to infinity, and the other part of the function becomes almost zero.
So the function will be something like:
f(x) = 2^(-x) - 2

A rollercoasterbrises 210 feet into the air, drops 240 feet, rises 80 feet before dropping another 30 feet again. Finally the rollercoaster drops another 50 feet. What is the height of the rollercoaster after the last drop
Answer:
-30 feet
Step-by-step explanation:
What we know:
The rollercoaster first rose 210 feet, so after rise 1, the height is +210 feet.
After that, it dropped 240 feet. This is greater than the 210 feet it initially rose, so the number is now negative. The height is now -30 feet.
210 - 240 = -|240-210| = -|30| = -30 feet
After that, it rose another 80 feet. That outdoes the eariler -30 feet, so we're back to a positive height. After that rise, the height is now +50 feet.
-30 + 80 = |80 - 30| = |50| = 50 feet
Then the last two drops combine for a 80-foot drop. This is greater than the +50-foot height it was at, so we're back at -30 feet.
50 - 80 -|80 - 50| = -|30| = -30 feet after the last drop
What is the value of x in the equation below?
29.46=13.82+4x
Answer:
x=3.91
Step-by-step explanation:
29.46=13.82+4x
13.82+4x=29.46
subtract 13.82 from both sides
4x=15.64
divide by 4
x=3.91
Cecile packages snack mix at a health food store. She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply? 18 pounds 23 pounds
Given:
Cecile uses [tex]\dfrac{1}{3}[/tex] of her supply of sunflower seeds to make a salted snack mix and [tex]\dfrac{2}{9}[/tex] of her supply to make an unsalted snack mix.
Cecile uses 10 pounds of sunflower seeds.
To find:
The total pounds of seeds in her supply.
Solution:
Let x be the total pounds of seeds in her supply.
Cecile uses [tex]\dfrac{1}{3}[/tex] of her supply of sunflower seeds to make a salted snack mix, i.e., [tex]\dfrac{1}{3}x[/tex].
Cecile uses [tex]\dfrac{2}{9}[/tex] of her supply to make an unsalted snack mix, i.e., [tex]\dfrac{2}{9}x[/tex].
Total sunflower seeds used = 10 pounds.
[tex]\dfrac{1}{3}x+\dfrac{2}{9}x=10[/tex]
[tex]\dfrac{3x+2x}{9}=10[/tex]
[tex]5x=10\times 9[/tex]
[tex]5x=90[/tex]
Divide both sides by 5.
[tex]x=18[/tex]
So, there are 18 pounds of seeds in her supply.
Therefore, the correct option is A.
find the value of x (9x-3)
The result of the multiplication is the value of x (9x-3) is: 9x² - 3x.
Here, we have,
given that,
the expression is: x (9x-3)
now we need to find the value of x (9x-3)
we have,
x (9x-3)
=> x × (9x-3)
so, we have to multiply this two terms.
now, we get,
=> x × (9x) - x × 3
=> 9x² - 3x
Hence, The result of the multiplication is the value of x (9x-3) is: 9x² - 3x.

There are 3 red marbles, 2 blue marbles, and 7 black marbles if you choose one marble, what is the probability that it will be a red marble?
Answer:
3:12
Step-by-step explanation:
3 + 2 + 7 = 12
3 = red marbles
12 = total marbles
Answer:
Probability of both red =3(182)=3(18!2!16!)=3153
Step-by-step explanation:
Let Ai be the event in which the i-th ball you grab is red. For the first ball you choose, you have 3 red marbles out of a total of 18. Therefore,
P(A1)=318.
For the second marble you grab, given that you already took a red one, that is, given A1, you have 2 red balls out of a total of 17, then
P(A2∣A1)=217.
Finally,
P(A1∩A2)=P(A1)P(A2∣A1)=318217=151.

Your family goes to a Southern-style restaurant for dinner. There are 6 people in your family.
Some order the chicken dinner for $14 and some order the steak dinner for $17. If the total bill
was $99, how many people ordered each dinner?
Answer:
We conclude that:
The number of people who ordered the chicken dinner = 1The number of people who ordered the steak dinner = 5Step-by-step explanation:
Given that
Some order the chicken dinner for $14some order the steak dinner for $17.Total bill = $99Let 'n' be the number of people who ordered the chicken dinner.Let '6-n' be the number of people who ordered the steak dinner.Thus, the equation becomes
[tex]14n + 17(6-n) = 99[/tex]
[tex]14n + 102 - 17n = 99[/tex]
[tex]-3n = 99 - 102[/tex]
[tex]-3n = -3[/tex]
Divide both sides by -3
[tex]n = 1[/tex]
and
[tex]6-n = 6-1 = 5[/tex]
Therefore, we conclude that:
The number of people who ordered the chicken dinner = 1The number of people who ordered the steak dinner = 5Damian has a balance of $10,200 on his credit card. He threw the card away so he can never use it again. He has 3 1/2 years to pay off the balance. The interest rate on his card is 21%. At the end of the 3 1/2 years, how much interest has he paid?
Answer:
the interest that have to paid is $9,676.91
Step-by-step explanation:
The computation of the interest to be paid is as follows:
= Future value - initial value
= $10,200 × (1 + 0.21)^3.5 - $10,200
= $19,876.91 - $10,200
= $9,676.91
Hence, the interest that have to paid is $9,676.91

Solve the following system:
y = 5x
3x + 2y = 52
Your answer:
After putting the value of y into the eq. (ii) ,
[tex] \sf 3x + 2 \times 5x = 52[/tex]
[tex] \sf ⇒ \: 3x + 10x = 52[/tex]
[tex]⇒ \sf13x = 52[/tex]
[tex] \sf ⇒x = 4[/tex]
After putting the value of x into the eq. (1)
[tex] \sf \: y = 5 \times 4[/tex]
[tex]⇒ \sf y = 20[/tex]
Hence, the value of x is 4
& the value of y is 20.

Formula used :
where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
Thus, the interest customer earn in 20 years will be, $ 660
