Answer:
16 cm
Step-by-step explanation:
Circumference of a circle
We are told that the string is wound symmetrically around a circular rod.
Now, the circumference of the rod is 4 cm and length is 12 cm.
Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.
Thus, one wound = 4 cm
Since the string makes 4 turns about the rod, then;
Length of string = 4 × 4 = 16 cm

Find the equation of the tangent to the curve y = 4x³- 5x² + x - 3 at the point where it crosses the y axis.
Answers
Answer:
y = x-3
Step-by-step explanation:
When the graph of this equation crosses the y - axis , the value of x is = 0.
sub in zero to find this y value = -3
so the point is (0, -3)
Now find the drivative of this equation....the derivative tells you the slope of the original graph at any given point
derivative = 12x^2-10x+1 this , when x = 0 shows slope = 1

Answers
The computation of the figure illustrates that 0.47 expressed as a fraction in simplest form is 43/90.
How to compute the fraction?From the information given, let a = 0.47. Now 10a = 4.777 .... equation i
100a = 47.77 ..... equation ii
Subtract equation i from ii
100a - 10a = 47 - 4
90a = 43
Divide both side by 90
90a/90 = 43/90
a = 43/90

richard has two circular sprinklers to water his rectangular backyard as shown.
Answers
Answer:
109.88 ft² (nearest hundredth)
Step-by-step explanation:
Formulae
Area of a rectangle = width × lengthArea of a circle = πr²To find the area of the lawn that is not watered, subtract the area of the 2 circles from the area of the rectangle.
From inspection of the diagram
width of rectangle = 2rlength of rectangle = 4rarea = 512 ft²Substituting the values into the area of a rectangle formula, and solving for r:
⇒ 512 = 2r × 4r
⇒ 512 = 8r²
⇒ r² = 64
⇒ r = ±8
As distance is positive, r = 8 ft
Area of one circle = π8² = 64π ft²
Therefore,
Area not watered = area of rectangle - 2 × area of circle
= 512 - 2(64π)
= 109.88 ft² (nearest hundredth)

Step-by-step explanation:
The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.
So inequality which models this situation will be -40°C < T < 125°C
