Take the first 2 and take out -7x2. bringing it to (-7x2)(x-3)+(3x-9)
then take out 3 on the right side.
-7x^2 (x-3)+3 (x-3)
factors to (3-7x2)(x-3)

Write the ratio as a fraction in simplest form. 10.8 seconds : 36 feet (Show work)

vodka [1.7K]

Answer: Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$

Step-by-step explanation:

Since we have given that

10.8 seconds : 36 feet

As we know that

$1\ second=\frac{1}{60}\ mile\\\\1\ second=90\ feet$

So, we use it :

10.8 seconds : 36 feet

$=10.8\times 90\ feet:36\ feet\\\\=972:36\\\\=27:1$

Hence, Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$

Find the component form of the vector that translates P(4,5) to p'.

olga_2 [115]

Answer:

The component form of the vector P'P is $\left \langle -7, 2 \right \rangle$

Step-by-step explanation:

The component form of the vector that translates P(4, 5) to P'(-3, 7), is given as follows;

The x-component of the vector = The difference in the x-values of the point P' and the point P = -3 - 4 = -7

The y-component of the vector = The difference in the y-values of the point P' and the point P = 7 - 5 = 2

The component form of the vector P'P = $\left \langle -7, 2 \right \rangle$
