Find the product (x+2t) exponent of 2
Answer:
x² + 4xtx + 4t²
Step-by-step explanation:
Given
(x + 2t)² = (x + 2t)(x + 2t)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 2t) + 2t(x + 2t) ← distribute both parenthesis
= x² + 2tx + 2tx + 4t² ← collect like terms
= x² + 4tx + 4t²
Shoes cost $60.00. Discount is 20%. Sales price is equal to?
$10
$20
$30
$40
Answer:
it is D ..................
Answer:
$40 is the sales price after a 20% discount.
(*Edited as the shoes are $50.00, not $60.00)
Step-by-step explanation:
When calculating discounts, we can convert the percentage to a decimal and multiply by the original sales price:
[tex]50(.20)[/tex]
Multiply.
[tex]50(.20)=10[/tex]
Subtract your product from the sales price.
[tex]50-10[/tex]
Subtract.
[tex]50-10=40[/tex]
This circle is centered at the point (2,6), and the length of its radius is 4. What is the equation of the circle?
Answer:
The equation of the circle with centre (h,k) and radius (r) can be written as :-
[tex] \\ \qquad \sf \: {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ [/tex]
So, we are given with :-
h = 2 k = 6 r = 4Now, by putting their value we can write the equation as :-
[tex] \\ \qquad\sf \: {(x - 2)}^{2} - {(y - 6)}^{2} = {4}^{2} (16) \\ [/tex]
Expanding this, we get :-
[tex] \\ \sf {x}^{2} - 4x + 4 + { y}^{2} - 12y + 36 = 16 \\ [/tex]
Rearranging and by subtracting by 16 from both sides we got standard polynomial as -
[tex] \\ \sf \: {x}^{2} + {y}^{2} - 4x - 12y + 20 = 0 \\ [/tex]
Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th floor to the street; but every time he returns, he rides the same self-service elevator only to the 15th floor, where he leaves the elevator and walks up the remaining five flights of stairs. What is happening? Why does he do that?
Answer:
He does that because he is short and his hand can't reach the 20th floor button
Step-by-step explanation:
Mitch does that simply because he is short.
When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.

Step-by-step explanation:
A red kangaroo and a gray kangaroo together weigh 139 kg. The red kangaroo weighs 35 kg less than the gray kangaroo. How much does the gray kangaroo weigh?
Answer:
Gray kangaroo weighs 87 kg.
Step-by-step explanation:
Total weight of the two kangaroo = 139 kg.
Let the weight of the gray kangaroo be represented by p.
Since the red kangaroo weighs 35 kg less than the gray kangaroo = (p - 35) kg.
Thus;
weight of gray kangaroo + weight of red kangaroo = 139 kg
p + (p -35) = 139
p + p -35 = 139
2p = 139 + 35
2p = 174
p = 87
The weight of the gray kangaroo is 87 kg.
Weigth of the red kangaroo = (87 - 35)
= 52 kg
The gray kangaroo weighs 87 kg.
let the weight of the gray kangaroo as G.
We have,
the red kangaroo weighs 35 kg less than the gray kangaroo.
So, the weight of the red kangaroo can be represented as G - 35.
We also know that the combined weight of the red kangaroo and the gray kangaroo is 139 kg. So we can write the equation:
G + (G - 35) = 139
Combining like terms:
2G - 35 = 139
Now, let's solve for G by isolating the variable:
2G = 139 + 35
2G = 174
Dividing both sides by 2:
G = 174 / 2
G = 87
Therefore, the gray kangaroo weighs 87 kg.

How far did the fisherman row if the entire trip took 2 hours?

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A fisherman can row upstream at 1 mph and downstream at 4 mph.
He started rowing upstream until he got tired and then rowed downstream to his starting point.
Let the time of row upstream is x hours
Let the time of row downstream be y hours
From the question:
x + y = 2
x = 2 - y
x = 4y
Solving the above two linear equations by substitution method:
2 - y = 4y
5y = 2
y = 2/5
y = 0.4 hours
Distance = speed×time
Distance = 4×0.4 = 1.6 miles
= 1.6×2 = 3.2 miles
Thus, the distance the fisherman rowed is 3.2 miles if the fisherman can row upstream at 1 mph and downstream at 4 mph.

I NEED TO KNOW NOW IT'S DUE!!
Last summer, Fred earned 16 dollars per day, and Maria earned 18 dollars per day together, they earned 1780 dollars. If Fred worked 5 more days than Maria, how many days did Maria work?
x = # of days Maria worked
x + 5 = # of days Fred worded
$16(x + 5) + $18x = $1780
Let's distribute the $16
$16x + $80 + $18x = $1780
Combine like terms
$34x + $80 = $1780
Subtract $80 from both sides.
$34x = $1700
Divide both sides by $34
x = 50 days
Maria worked 50 days
Blanca earns a yearly salary of $55,000. Isabel earns a yearly salary of $63,000. Blanca will receive a salary increase of $3,700 per year, and Isabel will receive a salary increase of $2,900 per year.
Which equation can be used to find n, the number of years it will take Blanca to earn the same salary as Isabel?
55,000n + 3,700 = 63,000 + 2,900n
55,000n + 3,700n = 63,000n + 2,900n
55,000n + 3,700n = 63,000n + 2,900
55,000 + 3,700n = 63,000 + 2,900n
PLSS ANSWER ILL MAKE MOST BRAINLIEST!!!!
Answer:
last choice: 55,000 + 3,700n = 63,000 + 2,900n
Step-by-step explanation:
Blanca's salary now: 55,000
Adding $3,700 per year will add 3,700n in year n.
Her salary in year n will be 55,000 + 3,700n
Isabel's salary now: 63,000
Adding $2,900 per year will add 2,900n in year n.
Her salary in year n will be 63,000 + 2,900n
We set the two total salaries equal:
55,000 + 3,700n = 63,000 + 2,900n

Kennedy invested $5,000 in an account paying an interest rate of 6.4% compounded
daily. Assuming no deposits or withdrawals are made, how much money, to the
nearest cent, would be in the account after 15 years?
The Answer is
A~13057.38
The money, to the nearest cent, would be in the account after 15 years is $13060.
What is Daily Compound Interest ?Due to the high frequency of compounding, daily compounded interest is larger than monthly/quarterly compounded interest since interest is accumulated on a daily basis and is determined by charging interest on principal plus interest gained on a daily basis
It is given in the question that Kennedy invested $5000
Interest rate = 6.4% compounded daily
Assuming no deposits and withdrawals
T = 15 years
The formula for amount obtained after 15 years when interest is compounded daily
[tex]\rm A = (P(1 + \dfrac{r}{n})^{nt})[/tex]
[tex]\rm A = (5000(1 + \dfrac{6.4}{365*100})^{365*15})[/tex]
A = 5000 * 2.612
A = $13060
Therefore , money, to the nearest cent, would be in the account after 15 years is $ 13060.

the discriminant of the equation 7√3x²+10x-√3 is...... plzz i need it fast
Step-by-step explanation:
Hey there!
Here,
The equation is:
[tex]7 \sqrt{3 \: } {x}^{2} + 10x - \sqrt{3 } = 0[/tex]
Comparing the equation with ax^2+bx+c=0. We get;
[tex]a = 7 \sqrt{3} [/tex]
[tex]b = 10[/tex]
[tex]c = \sqrt{3} [/tex]
Now,
Discriminant= ?
We have,
[tex]discriminant = {b}^{2} - 4ac[/tex]
Put all values.
[tex]discriminant = {10}^{2} - 4 \times 7 \sqrt{3} \times \sqrt{3} [/tex]
[tex]discriminant = 100 - 4 \times7 \times 3[/tex]
[tex]discriminant = 100 - 84[/tex]
