Answer:

log4(9)

Step-by-step explanation:

If y= $b^{x}$ , then x=log b(y)

firstly add 2 to both sides, this will end up with $4^{x} =9$

then just apply the statement i made above and you should get log4(9)

Kite EFGH is inscribed in a rectangle such that F and H are midpoints and EG is parallel to the side of the rectangle.

aivan3 [116]

Answer:

"The area of EFGH is always One-half of the area of the rectangle."

Step-by-step explanation:

<em>Graph is attached.</em>

<em />

The kite consists of 2 triangle, EFG and EHG.

The area of EFG:

$\frac{1}{2}*EG*h$

where h is the height from F to EG

The area of EHG:

$\frac{1}{2}*EG*h_1$

where $h_1$ is the height from H to EG

We also know that h + h _1 is the width of the rectangle and EG is the length of the rectangle

Thus,

Area of Kite = $\frac{1}{2}*EG*h + \frac{1}{2}*EG*h_1 = RectangleLength*RectangleWidth$

Also, Area of rectangle is rectangle length * rectangle width.

Thus, area of kite is always half of that of rectangle, the third choice is right.

Please help me find the area

laiz [17]

Answer:

594

Step-by-step explanation:

To find the area of a rectangle it is length * width

First break the shape into two shapes that are both rectangle

The find the length of the line on the tallest part, subtract 30 with 14

30 - 14 = 16

Lets first solve the taller one

16 * 24 = 384

Then solve the one on the left

14 * 15 = 210

Then add the both together to get the total area of the two shapes together

384 + 210 = 594

594 is your answer

Solve 5^x=81.2. Round to the nearest ten-thousands.

sasho [114]

Ln(5^x) = ln(81.2)
xln(5) = ln(81.2)
x= ln(81.2)/ln(5)
x= ln(406/5)/ln(5)
x = ln(406) - ln(5)/ln(5)
log (ab) = log(A) + log (B)
ln(2) +ln7 + ln(29 - ln(5)/ln(5)
x = 2.7320 (4dp)

Use rhombus TQRS below for questions 1–4.

UkoKoshka [18]

Answer:

Part 1) Option D $53\°$

Part 2) Option C $37\°$

Step-by-step explanation:

we know that

In a Rhombus

Opposite angles are congruent, and consecutive angles are supplementary. All sides are congruent by definition. The diagonals bisect the angles

Part 1) What is the measure of angle $1$ ?

$m$ -----> remember that the diagonals bisect the angles

Part 2) What is the measure of angle $2$ ?

Remember that

In a rhombus consecutive angles are supplementary

$m$

The measure of angle $2$ is equal to the measure of angle T divided by $2$

$m$
