What is the measure of angle 7?

1 answer:

Answer:

∠7 = 95°

Step-by-step explanation:

∠1 and ∠4 are vertical angles so they are equal.

so:

3x + 10 = 4x - 15

simplify:

x = 25°

∠4 = 4(25) - 15 = 85°

∠8 = ∠4 because they are corresponding angles

∠7 = 180° - 85° = 95° because they are supplementary angles (add together to = 180°)

How do I find the derivative of 2(f(x)+g(x))?

kramer

$\bf 2[f(x)+g(x)]\implies 2f(x)+2g(x)\implies 2\cfrac{df}{dx}+2\cfrac{dg}{dx}\\\\
-------------------------------\\\\
\cfrac{1}{2}\left[ f(x)\cdot g(x) \right]\implies \cfrac{1}{2}\left[ \stackrel{product~rule}{\cfrac{df}{dx}\cdot g(x)+f(x)\cdot \cfrac{dg}{dx}} \right]
\\\\\\
\cfrac{1}{2}\cdot \cfrac{df}{dx}\cdot g(x)+\cfrac{1}{2}\cdot \cfrac{dg}{dx}f(x)$

What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please

yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Please help with number 3!! I can’t figure it out.

FrozenT [24]

Answer:

Gabe worked 65, Abe worked 62 and Babe worked 69.

Step-by-step explanation:

Let Gabe = x

Therefore, Abe worked: x-3 and Babe worked x+4

So,

x+(x-3)+(x+4)=196

3*x+1=196

3*x=195

x=65

Then,

x-3= 62

x+4=69
