The fraction is 7/10 which means you can divid it to get the decimal or either you can write the fraction in decimal form by putting the 7 in the tenths place behind the decimal like this 0.7 which you will get the same if you divided them and I moved it to the right once being that it goes tenths hundredths thousandths and the fraction is 7 over 10 which means 7 tenths so I moved it once.

A quadratic function f(x)f(x) is hidden from view. You must find the xx-intercept(s) of f(x)f(x) and write the answer(s) in the

Alika [10]

f(x) should be in canonical form. So it must have the form

$f(x)=a(x-x_v)^2+y_v$

Where a is the main coefficient and is the vertex

Step-by-step explanation:

A quadratic function has a unique extreme value in its vertex. That value might be a maximum or a minimum depending on the sign of the main coefficient of the quadratic function. In order to quickly obtain the vertex, the quadratic must be written in canonical form. That means that f(x) must have the form

$f(x)=a(x-x_v)^2+y_v$

Where a is the main coefficient (which should be negative so that a minimum exists in the first place) and is the vertex. If f(x) is written in that form, then it will be easier to find the minimum of f(x), which is the vertex

Hence for the quadratic function below

$\begin{gathered} f(x)=(x-2)^2-9 \\ f(x)=x^2-4x-5 \\ ax^2+bx+c \\ a=1,\text{ b=-4, c=-5} \\ x_v=-\frac{b}{2a} \\ x_v=\frac{-(-4)}{2(1)} \\ x_v=\frac{4}{2} \\ x_v=2 \\ y_v=2^2-4(2)-5 \\ y_v=-9 \\ (x,y)\longrightarrow(2,-9) \end{gathered}$

Hence there is only one x- intercept and answer is (2, -9)

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain

GarryVolchara [31]

Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10

423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!

A lil help , What is g(h(10))?

PIT_PIT [208]

Answer:

2√2

Step-by-step explanation:

Given

g(x) = ✓(x - 4)

h(x) = 2x - 8

Now

g(h(10))

= g ( 2 * 10 - 8)

= g(20-8)

= g(12)

=✓(12 - 4)

= ✓8

=2√2

Hope it will help ✓
