If h(x)=6-x what is the value of (h•h)(110)

Mathematics
1 answer:
Irina18 [472]2 years ago
8 0

The given function : h(x) = 6 - x

We know that for any functions f(x) and g(x)

f*g (x)=f(x)\times g(x)

Therefore , h*h (x)=h(x)\times h(x)

h*h (x)=(6-x)(6-x)=(6-x)^2

h*h (x)=(6)^2-2(6)(x)+x^2 [ Using identity   (a-b)^2=a^2+2ab+b^2 ]

h*h (x)=36-12(x)+x^2

\-------->\ h*h (x)=36-12(x)+x^2 Now, at x= 10 , we get

h*h (10)=36-12(10)+(10)^2

h*h (10)=36-120+100=36+100-120=136-120=16

Hence, the value of (h*h)(10) = 16

hoped it helped

7.) Find the 3rd angle of the first triangle, then<br> find the value of x.<br> 600<br> 400<br> (x)
Salsk061 [2.6K]

Answer:

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180 so the third angle in the first triangle is 180 - 60 - 40 = 80

The value of x is 40 because given triangles are have two pair of angles that are equal.

Combine like terms to create an equivalent expression. 7.4z−5(−1.6z+2.4)
ryzh [129]

Answer:   15.4z-12

Step-by-step explanation:

For this exercise it is important to remember:

  • The Distributive property:

       a(b\±c)=ab\±ac

  • The multiplication of signs:

        (+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-

Then, given the following expression:

7.4z−5(-1.6z+2.4)

You need to  apply the Distributive property. Then:

=7.4z+8z-12

Now you can combine like terms (or add the like terms). Then you get:

=15.4z-12

Therefore, the equivalent expression created by combining like terms, is:

 15.4z-12

In 6 years, Mariya will be as old as Vikram is now. In 2 years, Vikram will be three times older than Mariya. Find their ages no
Damm [24]

Answer:

Mariya is 1 year old

Vikram is 7 years old

Step-by-step explanation:

Here, we want to know the present ages of Mariya and Vikram.

Let the present age of Mariya be M and the present age of Vikram be V

From the question, we are told that in 6 years time, Mariya will be as old as Vikram is now

Thus, mathematically;

M + 6 = V ••••••(i)

Furthermore , in 2 years time Vikram will be 3 time older than Mariya

Mathematically;

( V + 2) = 3( M + 2)

V + 2 = 3M + 6

V = 3M + 6-2

V = 3M + 4 •••••••(ii)

So let’s equate the V

3m + 4 = m + 6

3m -m = 6-4

2m = 2

m = 1

But V = m + 6

V = 1 + 6

V = 7
