Work Out Length ABD

Answers

Answer 1

Answer:

23.41

Step-by-step explanation:

AB is gotten using the pythagoras theorem

AB² =  AC² + BC²

AB² = 22² + 8²

AB² = 484 + 64

AB² = 548

AB = √548

AB = 23.41

Hence the length of AB is 23.41

A farmers field has the dimensions shown. He needs to find the area of the field so that he knows how much he needs to buy .Whats the area the field?

Answers

Answer:

Area of the rectangular Field = 3 8/9 km²

Step-by-step explanation:

Length of the field = 2 1/3 km

Width of the field = 1 2/3 km

Area of a rectangular Field = length × width

= 2 1/3 × 1 2/3

= 7/3 × 5/3

= (7*5)/(3*3)

= 35/9

Area of the rectangular Field = 3 8/9 km²

Perimeter of the rectangular Field = 2(length + width)

= 2(2 1/3 + 1 2/3)

= 2(7/3 + 5/3)

= 2(7+5/3)

= 2(12/3)

=2(4)

= 8 km

Perimeter of the rectangular Field = 8 km

Talia bought a home for her pet turtle the rectangular tank is 3 feet long. 1 foot wide and 2 feet high. What is the volume?

Answers

Answer:

Volume of rectangular tank = 6 cubic feet

Step-by-step explanation:

Length of the rectangular tank = 3 feet

Width of the tank = 1 feet

And height of the rectangular tank = 2 feet

Since, tank is in the shape of a cuboid,

Volume of a cuboid = Length × Width × height

                                 = 3 × 1 × 2

                                 = 6 cubic feet

Therefore, volume of the rectangular tank will be 6 cubic feet.

What is an exponential equation?

By locating the slope (m) and y-intercept (b) in the graph of a line, we can define a linear function in the form y=mx+b. By locating the common ratio (b) and y-intercept (a) in an exponential curve's graph, we can create an exponential function with the form y=aˣ.

Given an exponential equation 2²ˣ⁺¹ -5(2ˣ) + 2 = 0 for solving,

2²ˣ⁺¹ -5(2ˣ) + 2 = 0

(2ˣ)(2¹) -5(2ˣ) +2 = 0

2(2²ˣ) -5(2ˣ) + 2 = 0

2(2ˣ)² - 5(2ˣ) + 2 = 0

Let u = 2ˣ

Then : 2u² - 5u + 2 = 0

(2u - 1)(u - 2) = 0

2u - 1 = 0 ===> u = 1/2

u - 2 = 0 ===> u = 2

(i) 2ˣ = 1/2

2ˣ = 2⁻¹

x = -1

(ii) 2ˣ = 2

2ˣ = 2¹

x = 1.

Therefore, the value of the x for exponential equation 2²ˣ⁺¹ -5(2ˣ) + 2 = 0 will be 1 , -1.

The domain of this function is {–2, 3}. What is the minimum value in the range of this function? F(x) = -2x + 5

Answers

Answer:

-1

Step-by-step explanation:

Range are the output functions f(x) for input functions x

Since the minimum input functions is -2, we are to find the output that gives the lowest value

Given

F(x) = -2x + 5

Whn x = -2

F(-2) = 2(-2)+5

F(-2) = -4+5

F(-2) = 1

When x = 3

F(3) = -2(3)+5

F(3) = -6+5

F(3) = -1

This shows that the minimum value function is -1
