Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b

MAVERICK [17]

Answer: b=9

Step-by-step explanation: To find the slope we use: y2-y1/x2-x1

Which would then be: 5-b/-2-7= 5-b/-9

Then we have to find a number for b that would give us -4 as the numerator. That number would be 9

This would give us 4/9 which is the slope we already had.

The altitude of a triangle is 2 m longer than its base. What are the dimensions of the altitude and the base if thearea of the t

HACTEHA [7]

Step-by-step explanation:

Let base of triangle be x m.

Therefore, altitude =( x + 2)m

$area \: of \: \triangle = \frac{1}{2} \times base \times altitude \\ \\ 40 = \frac{1}{2} \times x \times (x + 2) \\ \\ 80 = {x }^{2} +2x \\ \\ {x}^{2} + 2x - 80 = 0 \\ {x}^{2} + 10x - 8x - 80 \\ x(x + 10) - 8(x + 10) = 0\\ (x + 10)(x - 8) = 0 \\ x + 10 = 0 \: \: or \: \: x - 8 = 0 \\ x = - 10 \: \: or \: \: x = 8 \\ base \: can \: not \: be \: - ve \\ x \neq - 10 \\ x = 8 \\ x + 2 = 8 + 2 = 10 \\$

Therefore

Altitude = 10 m

Base = 8 m

What is the exponential form of the logarithmic equation? 3=log0.6 0.216

tatuchka [14]

Answer:

0.216 = 0.6³

Step-by-step explanation:

using the rule of logarithms

• $log_{b}$ x = n ⇔ x = $b^{n}$

$log_{0.6}$ 0.216 = 3 ⇒ 0.216 = $0.6^{3}$

Points A, B and C lie on a circle, centre O.<br> Angle AOC = 142°.<br> Find the value of y.

aksik [14]

The value of the angle $y$ within the quadrilateral $OABC$ inscribed the circle is 142°.

Let suppose that quadrilateral $OABC$ is a parallelogram. Then, the following conditions must be fulfilled:

$\overline {OA} \cong \overline {BC}$
$\overline{AB} \cong \overline{OC}$
$\angle AOC \cong \angle ABC$

In addition, if we have a rhombus we have the additional condition as A, B and C lie on the circle:

$\overline{OA} \cong \overline {AB} \cong \overline {BC} \cong \overline{OC}$ (4)

If we know that $\angle AOC = 142^{\circ}$ , then the value of $\angle ABC = y = 142^{\circ}$ .

Based on all these finding, we conclude that the value of the angle $y$ within the quadrilateral $OABC$ inscribed the circle is 142°.
