Answer:

acceleration of the golf ball will be faster. ( A )

Step-by-step explanation:

if you DROP a bowling ball vs a golf ball, the bowling ball will drop faster cause it’s heavier. but if you push a golf ball vs a bowling ball with the same force, the golf ball will be faster because it’s lighter. pushing a bowling ball with a lot of force will move it a certain amount, but moving a golf ball with that same force will go way past the bowling ball just cause it’s lighter.

Simplify cotø(tanø+cotø)

Sladkaya [172]

Answer:

$\large\boxed{\cot\theta(\tan\theta+\cot\theta)=1+\cot^2\theta=\dfrac{1}{\sin^2\theta}=\csc^2\theta}$

Step-by-step explanation:

$\text{Use}\\\\\text{distributive property:}\ a(b+c)=ab+ac\\\cot\alpha\tan\alpha=1.\\\\======================\\\\\cot\theta(\tan\theta+\cot\theta)=(\cot\theta)(\tan\theta)+(\cot\theta)(\cot\theta)\\\\=1+\cot^2\theta\\\\\text{If you want next transformation, then use:}\\\\\cot\alpha=\dfrac{\cos\alpha}{\sin\alpha}\\\\\sin^2\alpha+\cos^2\alpha=1\\\\=======================$

$=1+\left(\dfrac{\cos\theta}{\sin\theta}\right)^2=1+\dfrac{\cos^2\theta}{\sin^2\theta}=\dfrac{\sin^2\theta}{\sin^2\theta}+\dfrac{\cos^2\theta}{\sin^2\theta}=\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta}\\\\=\dfrac{1}{\sin^2\theta}\\\\\text{If you want next transformation, then use:}\\\\\csc\alpha=\dfrac{1}{\sin\alpha}\\\\=\left(\dfrac{1}{\sin\theta}\right)^2=(\csc\theta)^2=\csc^2\theta$

What is the equation that goes through (4,5) and is parallel to y=2x+1

forsale [732]

Answer:

The equation would be y = 2x - 3

Step-by-step explanation:

To start, we need to note that they will have the same slope, since parallel lines have the same slope. Then, we can use the point-slope form to find the equation.

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 3

Answer:

87.5 ml tube of toothpaste slightly offers the better value of money.

Step-by-step explanation:

In order to know the better value of money, we need to find the volume of each toothpaste for 1p.

For first tube of toothpaste:

87.5 ml costs 49p

Therefore, for 1 p = 87.5/49 = 1.78571429 = 1.8 ml

For second tube of toothpaste:

125 ml costs 72 p

Therefore, for 1 p = 125/72 = 1.73611111 = 1.7 ml

Since, 1.8 ml > 1.7 ml

So, 87.5 ml tube of toothpaste slightly offers the better value of money.
