f(-4); f(x) = x2 + x - 4

Answers

Answer: 8

Step-by-step explanation: In this problem,

we're asked to find f(-4) or the value of the function when x = -4.

To find the value of the function when x = -4,we simply plug in a -4 for

the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.

So f(-4) = 8.

The measure of the second angle is 15 degrees more then the measure of the 1st angle. The measure of the 3rd angle is 45 degrees more than the measure of the 1st angle. Find the measures of the interior angles in the triangle.

Answers

Let the first angle be x

So, second angle = (x+15)°

and third angle= (x+ 45)°

Now,

x+ (x+15) + (x+45)= 180°. ( Triangle sum property)

x+x+x+15°+45° = 180°

3x+ 60° = 180°

3x= 180°-60°

3x= 120°

x= 120°/3

x= 40°

Now,

first angle=x= 40°

second angle = (x+15)°= 40°+15° = 55°

third angle= (x+45)° = 40°+45° = 85°

Hope it helps you. Please mark as brainliest if it does.

Calculate the rate of interest if principle is 6000 time is two years and interest 3000

Answers

Answer:

We conclude that the interest rate required to  accumulate simple interest of $3,000 from a principal of $ 6,000.00  over 2 years is 25% per year.

Step-by-step explanation:

Given

Principle P = 6000

Time period t = 2 years

Interest I = 3000

To determine

Interest rate r = ?

Using the formula

I = Prt

r = I / Pt

substituting P = 6000 , t = 2, and  I = 3000

r = 3000 / ( 6000 × 2 )

r =  3000 / 12000

r = 0.25

convering the decimal into percentage: 0.25×100 = 25%

r = 25%

Therefore, we conclude that the interest rate required to  accumulate simple interest of $3,000 from a principal of $ 6,000.00  over 2 years is 25% per year.

PLEASE HELP ILL GIVE BRAINLESS IM GOING TO FAIL

Answers

x=20
AD= 23
DC= 23
AC= 46


The median means both sides of the line AC are equal.

Therefore: x+ 3 = 2x-17
and we can solve this for x

Subtract x from both sides
x-x = 2x-x -17
3 = x -17

Add 17 to both sides
3 +17 = x -17+17
20 = x

The length of AD is x + 3, replace x with 20:
20 + 3 = 23



The length of DC is the same as AD (because they’re separated by the median) so DC= 46

AC is the length of AD + DC,
23+23= 46.
AC= 46

Answer:

(x, y) = (-2, -3)

WORK:

2x + 4y = -16  =

-2x + 2y = -2  =

(^ the two’s cancel out) =

6y = -18  =

(^ you need to divide 6 on both sides to get just y) =

6y/6 = -18/6  =

(^ the six’s cancel out) =

y = -3  =

(^ now you have to plug this in to get x) =

2x + 4(-3) = -16  =

2x - 12 = -16  =

(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =

2x = -4  =

2x/2 = -4/2  =

(^ now you divide 2 on both sides again to get just y, and they will cancel out) =

x = -2  =

THEREFORE YOU GET (-2, -3)

B. 2x (square) - y (cube)=2×6²-(-4)³=72--64=72+64=136

A: (5(6))/(3(-4)+(6)) = -5
B: 2(6)^2-(-4)^3 = 136

Answers

Step-by-step explanation:

consider the sign as equals then

move 2x right side 3 on left

solve it

answer is 2

Question is: 2x - 1 >= 4x + 3

First, join the like terms together.

-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.

-> The number 3 moves into the other side which also becomes negative.

Now the equation will look like this:

- 3 - 1 >= 4x - 2x

- 4 >= 2x

Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).

It looks like this now:

- 4/2 >= x

- 2 >= x

This is the answer.

The image shown is an object formed from a cylinder and spherical hemisphere. The radius of the base is 7 cm and the height of the cylinder is 10 cm

(π = 22/7). The volume of the object is ....
A. 2258,67 cm3
B. 2618,33 cm3
C. 2926,67 cm3
D. 2977,33 cm3

Answers

Answer:

Volume = 2,258.67 cm³

Step-by-step explanation:

Volume of the object = volume of hemisphere + volume of cylinder

= ⅔πr³ +πr²h

Where,

π = 22/7

r = 7 cm

h = 10 cm

Volume = (⅔*22/7*7³) + (22/7*7²*10)

Volume = 2,258.67 cm³
