You find that the product of 67 and 5 is 335. How can you use addition to check if you are correct? How can you use division to
daser333 [38]

Answer:  Well, there is two ways for addition and two ways for division. either Add 67 5 times (67 + 67 + 67 + 67+ 67) to get 335 or add 5 67 times (5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 etc.) to get 335, And for division (my favorite part) Either get 335 and see if 67 can be multiplied to get 3, 33, or 335. and if either 3, 33, or 335 is to big subtract what you get when you multiply (Enter Number) with 67 to get anything remotely close to 3, 33, or 335. (NOT MORE THAN 3, 33, OR 335 ONLY EXACT OR LESS THAN) or do the exact same with 5.

Find the distance between the points: (–6, 7) and (–1, –5). In your final answer, include the formula and calculations that you
expeople1 [14]

Answer: The distance between the points (-6,7) and (-1,-5) is 13 units.

Solution:

P1=(-6,7)=(x1,y1)→x1=-6, y1=7

P2=(-1,-5)=(x2,y2)→x2=-1,y2=-5

Distance between points P1 and P2: d=?

d=sqrt [ (x2-x1)^2 + (y2-y1)^2 ]

Replacing the knwon values:

d=sqrt [ (-1-(-6))^2 + (-5-7)^2 ]

d=sqrt [ (-1+6)^2 + (-12)^2 ]

d=sqrt [ (5)^2 + 144 ]

d=sqrt [ 25 + 144 ]

d=sqrt [ 169 ]

d=13

I need help plzzzzzzzzz
Zina [86]

Answer:

slope = - \frac{1}{3}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 0) ← 2 points on the line

m = \frac{0-1}{3-0} = - \frac{1}{3}

The line crosses the y- axis at (0, 1), thus y- intercept is 1

F(x) = 4√(2x³-1)<br> F'(x) =....?
icang [17]
y= \sqrt[4]{(2x^3-1)} \\ y^4=2x^3-1 \\ 2x^3=y^4+1 \\ x^3= \frac{y^4+1}{2} \\ x= \sqrt[3]{\frac{y^4+1}{2}}

Therefore, F'(x) = \sqrt[3]{\frac{y^4+1}{2}}
