A right triangle has an area of 24ft^2. The dimensions of the triangle are increased by a scale factor of 6. What is the area of

the new triangle

Mathematics

Nina [5.8K]3 years ago

Answer:

864\ ft^2

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=\frac{1}{2}bh

A=24\ ft^2

24=\frac{1}{2}bh -------> 48=bh ------> equation A

where

b is the base of the triangle

h is the height of the triangle

In this problem the dimensions of the triangle are increased by a scale factor of 6

so

the new dimensions of the triangle are

b=6b, h=6h

The new area of the triangle will be

A1=\frac{1}{2}(6b)(6h)

A1=18bh ------> equation B

Substitute equation A in equation B

A1=18[48]=864\ ft^2

4. How fast was a driver going if the car left skid marks that were 32 feet long on dry concrete? (The coefficient of friction i
Monica [59]

Answer:

v_{o} \approx 31.247\,mph

Step-by-step explanation:

The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:

a = \mu_{k}\cdot g

a = (1.02)\cdot \left(32.174\,\frac{ft}{s^{2}} \right)

a = 32.817\,\frac{ft}{s^{2}}

The initial speed is computed from the following kinematic expression:

v^{2} = v_{o}^{2} - 2\cdot a \cdot \Delta s

v_{o} = \sqrt{v^{2}+2\cdot a\cdot \Delta s}

v_{o} = \sqrt{\left(0\,\frac{ft}{s} \right)^{2}+2\cdot \left(32.817\,\frac{ft}{s^{2}} \right)\cdot (32\,ft)}

v_{o}\approx 45.829\,\frac{ft}{s}

v_{o} \approx 31.247\,mph

What are the solutions to the equation 3x2 + 3x +7 = 0?​
KATRIN_1 [288]

Answer:

x is equal to 0.94 and -1.94

Step-by-step explanation:

3x² + 3x + 7 = 0

9x² + 9x + 21 = 0

9x² + 9x + 2.25 = 18.75

(3x + 1.5)² = 18.75

3x + 1.5 = ±√18.75

3x = -1.5  ±√18.75

x = (-1.5  ±√18.75) / 3

x = 0.94, -1.94
