(35mph/60) = 0.583 miles per minute

25 min x 0.583 miles per min = 14.583 miles is the distance between home and office.

So 14.583miles/30min x 60 minutes = 29.167 mph

Answer:1. The measure of angle P is 53. 2. The value of x is 25.

3. The length of each side of the triangle is 30 cm.

Step-by-step explanation:

1. (3x +2) + (3x + 2 ) + (5x -11) =180 Angle Q and P have the same measures because it is an isosceles triangle that is why you have three expressions.

So x =17 and 3(17)+ 2 =53

2. (2x +10) + (2x+10) + (2x + 10)= 180 this is because the second triangle is an equilateral triangle which means all it have the same measures.

solve for x. and x is 25.

3.The third triangle is also an equilateral triangle so you will make the expressions equal each other and solve for y .

1/10y + 11= 3/5y -4

y= 30

Apply Newton’s method to estimate the solution of x3 − x − 1 = 0 by taking x1 = 1 and finding the least n such that xn and xn +

ss7ja [257]

Solution :

Given

$f(x)=x^3-x-1, x_1=1$

$f'(x)=3x^2-1$

Let the initial approximation is $x_1 =1$

So by Newton's method, we get

$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)},n=1,2,...$

$x_2=x_1-\frac{f(x_1)}{f'(x_1)}=1-\frac{1^3-1-1}{3(1)^2-1}=1.5$

$x_3=1.5-\frac{(1.5)^3-1.5-1}{3(1.5)^2-1}=1.34782608$

$x_4=1.34782608-\frac{(1.34782608)^3-1.34782608-1}{3(1.34782608)^2-1}=1.32520039$

$x_5=1.32520039-\frac{(1.32520039)^3-1.32520039-1}{3(1.32520039)^2-1}=1.32471817$

$x_6=1.32471817-\frac{(1.32471817)^3-1.32471817-1}{3(1.32471817)^2-1}=1.32471795$

$x_5 \approx x_6$ are identical up to eight decimal places.

The approximate real root is x ≈ 1.32471795

∴ x = 1.32471795

In one month a store had 1,222 in sales but expenses were 2,345 how much money did the store lose in that month

dangina [55]

We simply need to subtract 1,222 from 2,345. Once we do that we get 1,223. Hope that helps! :)
