Slope = (1-0)/(-2-4) = -1/6

POINT-SLOPE equation
y - 0 = -1/6(x - 4)

The Taylors plan to expand their

podryga [215]

Answer:

$A_{2} = 720\ ft^{2}$

Step-by-step explanation:

Let w and l be the width and length of the garage.

Let $A_{1}$ and $A_{2}$ be the area of garage at present and new garage.

Given:

The area of the garage at present

$A_{1}=80\ ft^{2}$

And he planed to tripling the dimensions of the garage.

We need to find the area of the new garage.

Solution:

We know the area of the rectangular garage.

$Area=width\times lendth$

$A_{1}=w\times l$

$w\times l=80$ ---------------(1)

The dimension of the new garage is triple, so the area of the new garage is.

$A_{2} = (3\times width)\times (3\times length)$

$A_{2} = (3\times w)\times (3\times l)$

$A_{2} = 9\times (w\times l)$

Substitute $w\times l=80$ from equation 1.

$A_{2} = 9\times (80)$

$A_{2} = 720\ ft^{2}$

Therefore, the area of the new garage $A_{2} = 720\ ft^{2}$

the height of an equivalent triangle is 15cm and it's perimeter is 36cm find the area of the triangle

OlgaM077 [116]

Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²

If p is true and ~ q is false, then p ~ q is always, sometimes, never false.

Paha777 [63]

Answer:

never

Step-by-step explanation:

The expression: ~q means "not q"

If ~q is false, then q is true

The expression:

If p is true and ~q is false

is equivalent to:

If p is true and q is true

then:

If p is true and q is true, then p -> q is never false (or is always true, see table attached). Or:

If p is true and ~q is false, then p -> ~q is never false.
