\huge\bold\red{Answer}

☑The diagram which is shown above is a rectangle.

✍ Perimeter= 60mm

✍ breadth = 5mm

➡ Perimeter of rectangle = 2(l+b)

✍ 60 = 2(l +5)

✍ 60/2 = l+5

✍ 30 - 5 = l

✍ 25 = l

☑ L = 25mm

❣..hope it helps you..❣

Answer:

x = 25 mm

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w) where l is the length and w is the width

We know the perimeter is 60 mm and the width is 5 mm and the length is x

60 = 2(x +5)

Divide each side by 2

60/2 = 2/2(x+5)

30 = x+5

Subtract 5 from each side

30-5 = x+5-5

25 =x

x = 25 mm

Find the value of X in X-X³=17​
Karolina [17]

Answer:

Step-by-step explanation:

Step1: find the interval of roots. Consider -3 and -2

f(-3) = -7

f(-2) = 18 >0

Hence, the root must be on [-3,-2]

Step2:  consider the middle point -2.5

f(-2.5) = 3.875 >0

Then, the root must be on [-3, -2.5]

Step 3: Repeat step 2 by finding the value of f at the middle point -2.75

f(-2.75) = -1.0468

Step 3: Repeat step 2 by finding the value of f at the middle point of the interval [-2.75,-2.5] which is -2.625

f(-2.625) = 1.537 >0

Step4: Repeat step 2 on [-2.75, -2.625]

Repeat step 2 until you got the root which is -2.701

What is the value of sin-1(1)? negative startfraction pi over 2 endfraction 0 startfraction pi over 2 endfraction π
mariarad [96]

The value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.

<h3>What is the value of sin (π/2)?</h3>

The value of sin (π/2) is equal to the number 1. The value of the sin-1(1) has to be find out.

Suppose the value of this function is <em>x</em>. Thus,

x=\sin^{-1}(1)

Solve it further,

\sin(x)=(1)              ......1

The value of sin (π/2) and -sin (-π/2) is equal to 1 such that,

\sin\dfrac{\pi}{2}=-\sin\left(-\dfrac{\pi}{2}\right)=1

Put this value in the equation 1,

\sin(x)=\sin\left(\dfrac{\pi}{2}\right)=-\sin\left(-\dfrac{\pi}{2}\right)

Thus, the range will be,

\left(\dfrac{\pi}{2},-\dfrac{\pi}{2}\right)

Thus, the value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.

Luis earns a base salary of $150.00 every week with an additional 14% commission on everything he sells. If Luis sold $6,050.00
max2010maxim [7]
Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050. 
x=150+(0.14x6050)
    150+(847)
    997
Luis was paid $997.
