Write this number in scientific notation.
Answer:
4.18 × 10^ 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
I am assuming that number began with a decimal point.
Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes
4.18X10^(-5)

-5x + 12 - 7x = -3(5x + 8)
Answer:
x = -12
Step-by-step explanation:
-5x + 12 - 7x = -3(5x + 8)
-5x + 12 - 7x = -15x - 24
-12x + 12 = -15x - 24
-12x + 15x = -24 - 12
3x = -36
x = -12

6.Write the equation of the line in slope-intercept form that has a slope of -4 and passes through the point (-1, -3).
Answer:
y = - 4x - 7
Step-by-step explanation:
Line is passing through the point (-1, - 3) and has a slope (m) = - 4
[tex]y - ( - 3) = - 4 \{x - ( - 1) \} \\ \\ y + 3 = - 4(x + 1) \\ \\ y + 3 = - 4x - 4 \\ \\ y = - 4x - 4 - 3 \\ \\ y = - 4x - 7[/tex]

19y^2+95y = ?
Answer:
Step-by-step explanation:
[tex]19y^{2} + 95y[/tex]
Both terms have a [tex]y[/tex] in them, so we can first start by factoring that out:
[tex]y(19y + 95)[/tex]
For the remaining two terms in the parenthesis, they both can have a [tex]19[/tex] factored out:

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet
is {(-7,8),(5,-5),(-7,-3)(3,-4,)} a relation a function
yes or no
Answer:
Step-by-step explanation:
A function can only have one y value for any given x value. If there is more than one value of y for a single x value it is said to have failed the ‘vertical line test.
Since there are points (-7,8) and (-7,-3) this is NOT a function.
BRAINLIEST and HELP!!!! A worker is connecting a cable from the rooftop of a school to a fence pole 7 ft away. The pole is 10 ft high. He uses 25 ft of cable to reach from the rooftop to the fence pole. How tall is the school?
(NOBODY ANSWER IF YOU DONT HAVE IT!!)
Answer:
yee its 34ft..........
Height of the school building is equals to 34ft.
What is height?
" Height is defined as one of the dimension which represents the distance between base and the top."
Formula used
Pythagoras theorem
(Hypotenuse)² = (Opposite side)² + (adjacent side)²
According to the question,
'h+ 10 ' represents the height of the building
As shown in the figure,
In the right triangle
' Hypotenuse' represented by length of the cable = 25ft
Adjacent side = 7ft
'h' is the height of the triangle
Substitute the value in the Pythagoras theorem we get,
[tex](25)^{2} = 7^{2} + h^{2}[/tex]
⇒ [tex]h^{2} = 625 - 49[/tex]
⇒ [tex]h = \sqrt{576}[/tex]
⇒ [tex]h = 24[/tex] ft.
Therefore,
Height of the school building [tex]' h + 10 '= 24 + 10[/tex]
[tex]= 34[/tex] ft.
Hence, height of the school building is equals to 34ft.

The average life expectancy of people in the united states in 2018 was 78.54 years with a standard deviation of approximately 15 years
Question:
The average life expectancy of people in the United States in 2018 was 78.54 years with a standard deviation of approximately 15 years.
Suppose we take a sample of 40 individuals in the United States, what are the mean and standard deviation for sample averages from samples of size 40?
Answer:
[tex]\bar x = 78.54[/tex]
[tex]\sigma_x = 2.37[/tex]
Step-by-step explanation:
Given
[tex]\mu = 78.54[/tex] --- Population mean
[tex]\sigma = 15[/tex] --- Population standard deviation
[tex]n = 40[/tex] --- Sample size
Solving (a): The sample mean
According to the central limit theorem, sample mean is always equal to the population mean.
So:
[tex]\bar x = 78.54[/tex]
Solving (b): The sample standard deviation
Using the central limit theorem, we have:
[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]
So:
[tex]\sigma_x = \frac{15}{\sqrt{40}}[/tex]
[tex]\sigma_x = \frac{15}{6.32}[/tex]
[tex]\sigma_x = 2.37[/tex]

$400 interest is earned on a principal of $2,000 at a simple interest rate of 59
interest per year. For how many years was the principal invested?
Answer:
6.779 years if the interest rate is in dollars.
Step-by-step explanation:
If its 59 percent, it would be well less than a year.
However, if not, divide 400 by 59.
If so, multiply 2000 by .59 to get the per year interest,
then, divide 400 by 1180 to get the answer of 0.33898

Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left
Answer:area of 4 equal circle having
Diameter =2ft
Therefore radius =r=2/2=1ft
Area of 4 equal circle =4(πr²) =4π×1²=4πft²
Area of square=length²=4²=16
Area of shaded region =area of square-
area of 4 equal circle

A, B & C form a triangle where ∠ BAC = 90°. AB = 6 mm and CA = 7.3 mm. Find the length of BC, giving your answer rounded to 1 DP.
Answer:
BC ≈ 9.5 mm
Step-by-step explanation:
Since, ΔBAC is a right angle triangle,
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = AB² + AC²
BC² = 6² + (7.3)²
BC = [tex]\sqrt{89.29}[/tex]
BC =
BC = 9.445
BC ≈ 9.5 mm

In right ABC angle c is the right angle, AC = 7, and BC = 24. Find the value of the sine of the largest acute angle of the triangle.
Answer:
Step-by-step explanation:
Remark
AC and BC are the legs of a triangle. You are told that the right angle is at C. Both these sides have one endpoint C. That means that they are the shorter of the three lines. The first thing we must do is find the Hypotenuse. You need the Hypotenuse to get the sin of one or both of the acute angles.
Hypotenuse
a^2 + b^2 = c^2
a = 7
b = 24
c = ?
c^2 = 7^2 + 24^2
c^2 = 49 + 576
c^2 = 625
sqrt(c^2) = sqrt(625)
c = 25
Find the Largest Angle
The largest angle is going to be opposite the longest leg (not the Hypotenuse although you use the hypotenuse).
Sin(A) = 24/ 25
Sin(A) = 0.96
A = Sin-1(0.96)
A = 73.74
Fully factorise 12r + 16
Answer:
4(3r+4)
Step-by-step explantion:
The factorized form of the given expression is 4(3r+4).
The given expression is 12r+16.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
Factorization of the expression 12r+16 is as follows
Here, in terms 12r=2×2×3×r and 16 =2×2×2×2, we have 4 has common factor
So, 4(3r+4)
Hence, the factorized form of the given expression is 4(3r+4).

Find sin 0, where is the angle shown.
Give an exact value, not a decimal approximation.
Answer:
sinθ = [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ = [tex]\frac{24}{25}[/tex] will be the answer.
