Answer: 6400<em>x²</em> · (<em>x - 1)²</em>

The rule says: To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is (x-1) and the exponents are:

1, as (x-1) is the same number as (x-1)1

And 1, as (x-1) is the same number as (x-1)1

The product is therefore, (x-1) (1 + 1) = (x-1)²

The Total Surface Area for the shape below is _________. (round to nearest tenth.)

gavmur [86]

Answer:

=193.2 cm

Step-by-step explanation:

Figure out the triangles first
Area= Base times Height divided by 2
first figure out one triangle A= (6)(5.2)/2 = 15.6 (brackets means times and the slash means divide
times it by 2 so you get the area of both triangles (15.6)(2)= 31.2
Now figure out the rectangles
Area= Base times Height
A=(6)(9) = 54
Then times it by 3 to get the area of all three triangles
(54)(3)= 162
Now add 162 and 31.2 and you get 193.2 cm

Write an equation with the two points: (5,-2) and (3,4)

eimsori [14]

Answer:

$y=-3x-17$

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

$\frac{y_2-y_1}{x_2-x_1}$ .

Substitute the values:

$\frac{4--2}{3-5}$

Combine the values:

$\frac{6}{-2}$

Find the value of the fraction:

$-3$

M is -3.

The equation so far is $y=-3x+b$

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

$y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b$ .

We see that b =-17 so the full equation would be:

$y=-3x-17$ .

Dan buys a car for £2100.

SVETLANKA909090 [29]

Answer:

£1837.5

Step-by-step explanation:

Given data

Cost of car P= £2100.

Rate r= 2.2%

Time t= 6 years

Now we want to find the worth after 6 years, let us apply the compound interest expression but this time for depreciation

A= P(1-r)^t

Substitute

A= 2100(1-0.022)^6

A= 2100*(0.978)^6

A= 2100*0.875

A= £1837.5

Hence the amount of the car after 6 years is £1837.5
