what is the value of W?
So, Q is the mid-point of UR.
Similarly, UT = TSSo, T is the mid-point of US.
So, QT is parallel to RS and half of it.Given, QT = w and RS = w + 37Therefore, QT = 1/2 RSor, w = 1/2(w + 37)
or, w = w/2 + 37/2
or, w - w/2 = 37/2
or, w/2 = 37/2
or, w = 37/2 × 2
or, w = 37.
Answer:The value of w is 37.

What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?
Answer:
y = x + 1
Step-by-step explanation:
The gradient of a line can be defined by the equation:
m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript
For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):
x2 = -7, y2 = -6
Plug these values into the formula above:
m = (y-(-6)) ÷ (x-(-7))
m = (y+6) ÷ (x+7)
At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.
x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:
y = x-7 ---> The gradient (coefficient of x) is 1.
Therefore, the gradient of the other parallel line must also be 1.
This can be substituted into the previous equation to give:
1 = (y+6)÷(x+7)
x+7 = y+6
x+1 = y
Therefore, the answer is y=x+1

james borrows Php 700000 and promises to pay the principal and interest at 15% compounded monthly. How much must he repay after 7 yrs?
Answer:
A = $ 1,987,379.10 + 700,000= $2,687,379.10
Step-by-step explanation:
15% = 0.15 rate per tear
A = P (1+r/n)^nt
A = 700,000 (1+0.015/12)^12*7
A = 700,000 (1+0.0125)^84
A = 700,000 ((0.9875)^84
A = 700,000 (2.839113)
James will have to pay PHP 1987379.1 after 7 years.
What is the interest rate?The percentage that a lender adds to the amount of money lent to them is called an interest rate.
Given that, James borrowed, 700000 at an interest rate of 15% compounded monthly.
The formula for the final amount in compound interest is:
A = P (1 + r/n)ⁿˣ
Where P is the principal amount, n is the number of times of compounding in a year, r is the interest rate, and x is the time in years.
Substitute the values in the formula:
A = 700000(1 + 15%/12)¹²⁽⁷⁾
A = 700000( 1 + 0.15/12)⁸⁴
A = 700000(1.0125)⁸⁴
A = 1987379.1
Hence, James will have to pay PHP 1987379.1 after 7 years.

The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)} is a function. What do you notice about the two groups of points? What do you think it means to be a function? plsss help yall i need the answer for a disscussion and this teacher NEVER give anybody an 100% on disscussions so at least get me an 80
Answer:
I notice that the first group of points contain multiple Y Values for the same X. Notice how 0 could be 1 or 5. The second group has a unique Y for every X. A function is a deterministic system where, given a X, it will map exactly one Y value.

find a series expansion for pi using the Maclaurin expansion for arctan(x) and the fact that tan(pi/4)
Recall that for |x| < 1, we have
[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]
It follows that, for |-x²| = |x|² < 1, or just |x| < 1,
[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{k=0}^\infty (-x^2)^k = \sum_{k=0}^\infty (-1)^k x^{2k}[/tex]
Taking the antiderivative of both sides gives us
[tex]\displaystyle \arctan(x) = C + \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
where C is a constant, which we determine to be 0, since taking x = 0 on both sides makes the series vanish, while arctan(0) = 0 since 0 = tan(0). So
[tex]\displaystyle \arctan(x) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
Since tan(π/4) = 1, it follows that π/4 = arctan(1), so in the series we replace x = 1, then solve for π :
[tex]\displaystyle \arctan(1) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} 1^{2k+1}[/tex]
[tex]\displaystyle \frac\pi4 = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1}[/tex]
[tex]\displaystyle \pi = \sum_{k=0}^\infty \frac{4(-1)^k}{2k+1}[/tex]
[tex]\pi = 4 - \dfrac43 + \dfrac45 - \dfrac47 +\cdots[/tex]
