Identify the ordered pair that represents the vector from a(-9 9) to b(7 3) and the magnitude of AB
Viefleur [7K]
Moving from a to b, the x component  of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.

So the vector from a to b is <16,-6>, and the magnitude is

sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.

Shirley is drawing triangles that have the same area. The base of each triangle varies inversely with the height. What are the p
Sphinxa [80]

The possible base and height of a second triangle are 12 and 7, respectively

<h3>How to determine the possible base and height of a second triangle?</h3>

An inverse variation is represented as:

Base * Height = k

Where k is the constant of variation.

In this case, k is the area

So, we have:

Base * Height  = Area

For the first triangle, we have:

14 * 6 = Area

Evaluate

Area = 84

Substitute Area = 84 in Base * Height  = Area

Base * Height  = 84

Express 84 as the product of two numbers

Base * Height  = 12 * 7

By comparison;

Base =12 and Height = 7

Hence, the possible base and height of a second triangle are 12 and 7, respectively

For whаt vаluе оf x does 3^4х = 27^x-3?
Marta_Voda [28]

Answer:

x = -9

Step-by-step explanation:

3^4х = 27^(x-3)

Replace 27 with 3^3

3^4х = 3^3^(x-3)

We know that a^b^c = a^ (b*c)

3^4х = 3^(3(x-3))

Since the bases are the same, the exponents are the same

4x = 3(x-3)

Distribute

4x =3x-9

Subtract 3x from each side

4x-3x = 3x-3x-9

x = -9

What is the value of x?
Morgarella [4.7K]

Answer

The value of x is 6.2 units .

Step-by-step explanation:

Now by using the pythagorean theorem

Hypotenuse² =  Perpendicular² + Base²

Now in the Δ ABD

As given

DB² = DA² + AB²

As given

DB = 13 units

AB = 9 units

Putting values in the above

13² = 9²+ DA²

169 - 81 = DA²

88 = DA²

DA = \sqrt{88}

In ΔABC

AB² = AC² + CB²

(As given AB = 9 units , CB = x)

9² = AC² + x²

AC ² = 81 - x²

Now in ΔADC.

AD² = AC² + DC ²

As

AC ² = 81 - x²

DC = 13 - x

AD = \sqrt{88}

(\sqrt{88})^{2}=81-x^{2} + (13-x)^{2}

(By using the formula (a + b)² = a² + b² + 2ab )

88=81-x^{2} + 13^{2}-2\times 13\times x + x^{2}

88=81-x^{2} + 13^{2}-26x+ x^{2}

88-81 - 169 = -26x

88-250 =-26x

-162 = - 26x

x = \frac{162}{26}

x = 6.2 (Approx)

Therefore the value of x is 6.2 units .
