Step-by-step explanation:

anything for sangwoo

Answer 2

The numeric value of this expression is -6!

To find out what the value of this expression is, let's replace f(x) with f(-3) and perform the given math operations.

[tex] \large \sf f(x) = 12 - 2x {}^{2} [/tex]

[tex] \large \sf f(-3) = 12 - 2\cdot (-3){}^{2} [/tex]

[tex] \large \sf f(-3) = 12 - 2\cdot 9 [/tex]

[tex] \large \sf f(-3) = 12 - 18 [/tex]

[tex] \boxed{ \boxed{{ \large \sf f(-3)=-6}}}[/tex]

Therefore, the result of this expression is f(-3)=-6. ✅

The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?

Answers

Answer:

24 kilometers

Step-by-step explanation:

Given

Represent the distance with x

[tex]x = 2km\ 400m[/tex]

Required

The distance covered for 5 days (i.e. Monday to Friday)

First, we calculate the distance covered in a day

He covers the same distance when going to school and when coming back from school.

So, the daily distance is:

[tex]Daily = 2 * x[/tex]

[tex]Daily = 2 * (2km\ 400m)[/tex]

[tex]Daily = 4km\ 800m[/tex]

In 5 days, he covers:

[tex]5\ days = 5 * Daily[/tex]

[tex]5\ days = 5 * (4km\ 800m)[/tex]

[tex]5\ days = 5 * (4km+ 800m)[/tex]

Open bracket

[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]

[tex]5\ days = 20km+ 4000m[/tex]

Convert m to km

[tex]5\ days = 20km+ 4km[/tex]

[tex]5\ days = 24km[/tex]

Answer and Step-by-step explanation:

We are told that there is 24 cupcakes, which total up to be 36 dollars.

c will represent One cupcake.

We would do 36 divided by 24 to find the cost of One cupcake.

[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]

Each cupcake (c) is equal to $1.5.

Equations that would get us to this would be:

36/24 = c

36 = 24c

The measures of the angle of a triangle are shown on the figure below. Solve for X.

Answers

Internal angles sum: 180(sides-2) = 180

5x = 180 - (48 + 90 + 17)

x = 25/5

x = 5

answer: 5

proof:

(90 + 48) + (5(5)+17) = 180

Answer:

x=5

Step-by-step explanation:

We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.

Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.

Now set the unknown angle equal to 42. (5x+17) = 42

Subtract 17from both sides to get 5x=25

Divide 5 from both sides to get x=5
