Mathematics
1 answer:
ludmilkaskok [199]3 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

sin x can only have values as shown

- 1 ≤ sin x ≤ 1

That is for sin x + 2 to equal zero then sin x  must equal - 2

However, sin x ≠ - 2

Hello, 

First of all the point-slope equation will have this form :   y=ax+b

b = y-intercept = 3\\\\a=\dfrac{\Delta y}{\Delta x}=\dfrac{-3-5}{2}=-4\\\\y=-4x+3

Answer A.

Because : 
if:y+5=-4(x-2)\\\\y+5=-4x+8\\y=-4x+8-5\\y=-4x+3

Estimate the product of 67 x 23<br> by rounding to the nearest ten.
elena-14-01-66 [18.8K]

Answer:

1400

Step-by-step explanation:

67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.

So, 70x20=1400

What number is 32.5% of 38.4
vodomira [7]
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48

What is the remainder when (3x4 + 2x3 − x2 + 2x − 19) ÷ (x + 2)?<br><br> 0<br> 5<br> 10<br> 15
Elanso [62]

Answer:  Second option is correct.

Explanation:

Since we have given that

f(x)=3x^4+2x^3-x^2+2x-19

And g(x)=x+2

To find the remainder, we use the Remainder Theorem, which states that when f(x) is divided by (x-c) then the f(c) is the required remainder.

So,

Here, we have,

x+2=0\\\\x=-2

So, we will find f(-2) which will give us the required remainder,

f(-2)=3(-2)^4+2(-2)^3-(-2)^2+2(-2)-19\\\\f(-2)=(3\times 16)-(2\times 8)- 4-4-19\\\\f(-2)=48-16-36-4-19\\\\f(-2)=5

Hence, Second option is correct.
