Solve for this equation for x round your number to the nearest hundredth 0.98=log x

Answers

Final answer:

To solve 0.98 = log x, you determine the number x for which 10 raised to the power of 0.98 equals x. Using a calculator, you find that x is approximately 95.50.

Explanation:

To solve the equation 0.98 = log x, we need to find the value of x such that when you take the common logarithm (base 10) of x, you get 0.98. A common logarithm is a logarithm with base 10, and the equation informs us that x is 10 raised to the power of 0.98 since y = log10(x) can be rewritten as x = 10y.

To find x, we can use the inverse operation of logarithm, which is exponentiation. We can express this process as follows:

x = 100.98

Using a calculator with exponentiation functionality, we enter the value of 0.98 and use the 10x function (sometimes labeled as INV or SHIFT followed by the LOG key).

The result is that x is approximately 95.50 when rounded to the nearest hundredth.

Say you own 316 shares of Esti Transport stock, which offers an annual dividend of $8.16 per share. How much will you receive in quarterly dividends?

Answers

Answer:

$644.64

Step-by-step explanation:

Total shares=316

Annual Dividend on 1 share =$8.16

Annual Dividend on 316 shares=$8.16*316

=$2578.56

As there are four quarters in a year, the total annual dividend will be divided by 4 to get the quarterly dividend.

Find the lateral area of a right circular cone whose radius is 6 feet and height is 8 feet.

Answers

Final answer:

The lateral area of a right circular cone with a radius of 6 feet and height of 8 feet is 60π square feet. We calculate this by first finding the slant height using the Pythagorean Theorem and then substituting the radius and slant height into the formula for the lateral area of a cone.

Explanation:

The lateral area of a cone can be calculated using the formula πrl, where r is the radius and l is the slant height. However, in this question, we're not provided the slant height, but the height. Therefore, we first need to find the slant height using the Pythagorean theorem, since a right circular cone forms a right triangle with the radius and the height. Using Pythagorean theorem, the slant height (l) can be found as

l = √(r² + h²) = √((6ft)² + (8ft)²) = 10ft.

Substitute the values of r and l into the formula for lateral area: πrl = π × 6ft × 10ft = 60π ft².

So, the lateral area of the cone is 60π square feet.

Remember to always use the correct units when solving such problems.

You have to ask yourself the meaning of h(0)

A building lot in a city is shaped as a 30°-60°-90° triangle, like the figure shown.

The side opposite the 30° angle measures 41 feet.

A) find the length of the side of the lot opposite the 60° angle.(show how I know).

B) find the length of the hypotenuse of the triangular lot.(show how I know)

Answers

check the picture below.
A) You can find the length of the side of the lot opposite the 60° angle  (which we will call "x") as below:

 Tan(α)=Opposite/Adjacent

 α=60°
 Opposite=41 feet
 Adjacent=x

 When you substitute these values into Tan(α)=Opposite/Adjacent, you obtain:

 Tan(60°)=x/41
 (41)Tan(60°)=x
 x=41√3
 x=71.01 feet

 B) Now, you can find the length of the hypotenuse:

 Cos(α)=Adjacent/Hypotenuse

 α=60°
 Adjacent=41 feet
 Hypotenuse=y

 When you substitute these values into Cos(α)=Adjacent/Hypotenuse, you obtain:

 Cos(60°)=41/y
 yCos(60°)=41
 y=41/Cos(60°)
 y=82 feet

Part 2 options
(-52,141)

(54,-128)

Answers

1. (18/5,0)
First let us find the equation of AB. It should be in the form of y=mx + b
From the given coordinates, you can get m, x, and b.

m= y2-y1 divided by x2 - x1
m=(6-2)/(7- -3)= 4/10 or 2/5
m= 2/5

b is your y intercept
To get it, use 1 coordinate either from point A or B.
Let point A be the coordinates
y=mx + b
-3= 2/5(2) + b
b= - 3- 4/5
b= 16/5


Now we will find the equation of CD,
y=mx + b
y= (-5/2)x + b
Then get the coordinates of point C through midpoint equation,
(x1+x2) /2, (y1+y2) /2
(-3+7)/2, (2+6)/2
=C(2,4)
We will use this coordinates to find b,
y=mx+b
4=(-5/2)2+b
4+5=b
b=9
If we are finding the x intercept, y value should be 0.
0=(-5/2)x+9
0-9(2)/-5=x
x= 18/5
The x intercept of CD is (18/5,0)

The perimeter is the sum of all sides. Start by listing out what the sides are given to be. Assign a variable to anything unknown.

1st side = x
2nd side = y
3rd side = z

Given: 1st side is 5 less than 2nd side.
x = y - 5

Given: 3rd side is 2 less that 1st side. But we want everything in only one variable to solve. So use the first given 1st side = y - 5
z = y - 5 - 2
z = y - 7


Sum of sides
(y - 5) + y + ( y - 7) = 42

3y - 12 = 42
3y = 42 + 12
3y = 54
y = 54/3
y = 18

Remember the sides, We have 
1st, x = y - 5
= 18 - 5
= 13

2nd, y = y
= 18

3rd, z = y - 7
= 18 - 7

The length of a rectangle is 3 times its width. if the width is diminished by 1 inch and the length is increased by 3 inches. the area of the the new rectangle is 72 square inches. find the dimensions of the original rectangle.

Answers

Final answer:

The width of the original rectangle is 5 inches and the length is 15 inches.

Explanation:

Let's assume the width of the original rectangle is x inches. According to the problem, the length of the rectangle is 3 times its width, so the length of the original rectangle is 3x inches.

When the width is diminished by 1 inch, the new width becomes x - 1 inches. And when the length is increased by 3 inches, the new length becomes 3x + 3 inches.

The area of a rectangle is given by length multiplied by width, so we can set up the following equation:

(x - 1)(3x + 3) = 72

By multiplying out the terms and rearranging the equation, we get:

3x^2 + 6x - x - 3 = 72

Combining like terms and simplifying further:

3x^2 + 5x - 75 = 0

Solving this quadratic equation gives us two possible answers for x: x = -5 or x = 5.

Since the width cannot be negative, we discard the negative value of x. Therefore, the width of the original rectangle is 5 inches and the length is 3 times the width, which is 3 * 5 = 15 inches.

Given is a Right triangle PQR with angle Q = 90 degrees.

Given are sides PQ = 8 cm, QR = 15 cm, PR = 17 cm.

Side PR is the hypotenuse.

We can use formula for "sin" given as follows :-

[tex] sin(\theta)=\frac{Opposite}{Hypotenuse} [/tex]

For angle R, opposite side would be PQ.

[tex] sin(R)=\frac{PQ}{PR} \\\\
sin(R)=\frac{8}{17} \\\\
sin(R)=0.470588235 \\\\
R=sin^{-1}(0.470588235) \\\\
R = 28.07248694 \;\;degrees \approx 28.07 \;degrees [/tex]

For angle P, opposite side would be QR.

[tex] sin(P)=\frac{QR}{PR} \\\\
sin(P)=\frac{15}{17} \\\\
sin(P)=0.882352941 \\\\
P=sin^{-1}(0.882352941) \\\\
P = 61.92751306 \;\;degrees \approx 61.93 \;degrees [/tex]

Hence, R = 28.07 degrees and P = 61.93 degrees.

To solve the problem we must know about Trigonometric functions.

The value of the ∠R is 28.0724°.The value of the ∠P is 61.9275°.

Given to usPR = 17 cmQR = 15 cmPQ = 8 cm

1. For ∠R

For ∠R, the opposite side will be PR, therefore, PR will be the Perpendicular,

Substituting the values in the formula of Sine,
