Find the area of the isosceles triangle.
13 cm is the side length
10 cm is the base length
what is the hight?
and area?

Answers

Answer 1

Answer:

Step-by-step explanation:

As we know that,

Area of isosceles triangle= 1/2 *b*h

we have a=10  and  other side = hypotenuse=b=13 cm

Now e have formula to find h,

h=[tex]\sqrt{b^{2} -a^{2}/4}[/tex]

now putt the values ,

we get,

h=[tex]\sqrt{169-100/4}[/tex]

h=[tex]\sqrt{576/4}[/tex]

h=12 cm  height of isosceles triangle ,

Area = 1/2 * b*h

Area=1/2*13*12

Area=S=60[tex]cm^{2}[/tex]

Reasoning A cylindrical water tank holds 26 litres when full. The water tank is 36 cm tall.
Work out the radius of the tank to 2 d.p.
(4 marks)

Answers

Answer:

r = 15.16 cm

Step-by-step explanation:

Mathematically, we need a consistent unit

26 liters = 26,000 cm^3 as 1000 cm^3 = 1 L

The volume of a cylinder is;

V = pi * r^2 * h

26,000 = 3.142 * r^2 * 36

r^2 = 26,000/(3.142 * 36)

r^2 = 229.86

r = √229.86

r = 15.16 cm

what do you call a crushed angle ?

Answers

Answer:

A Rectangle

Step-by-step explanation:

a wrecked angle

A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.

This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.

Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.

Can somebody help telling what does it mean? what does it want us to do? ​

Answers

Answer:

see explanation

Step-by-step explanation:

Give the graph of y = f(x) then y = f(x + a) represents a horizontal translation of y = f(x)

• If x > 0 then a shift to the left of a units

• If x < 0 then a shift to the right of a units

Thus

y = f(x - 2) is the graph of y = f(x) translated 2 units right

If f(x)= -2x+3 , find f(-1)?

Answers

Before we solve the equation let's take a look at it.

f(x) = -2x + 3

See how x appears in both f(x) and as the variable in the second half of the equation?

f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.

So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."

Catching on? We need to replace x with -1 to solve for f(-1).

So here we go:

f(x) = -2x + 3

f(-1) = -2(-1) + 3

f(-1) = 2 + 3

f(-1) = 5

Voilà! We have solved for f(-1). Hope this helped.
