Answer:
b = 1.778279, −1.778279
Step-by-step explanation:
-10=b4 <----- Write your equation out
-10=[tex]\frac{b4}{4}[/tex] <----- Divide b4 by 4 to get b by itself.
[tex]\frac{-10}{4}[/tex]=b <----- Divide -10 by 4 because what you do to one side, you mjst do to the other.
-2.5=b <----- There is your answer; -2.5

DESCRIBE IN WORDS THE TRANSLATION OF x represented by the translation rule <-6,8> (X) A. 6 units to the right and 8 units down B. 6 units to the left and 8 units up C. 8 units to the left and 6 units down D. 6 units to the right and 8 units up
Given:
Translation of x represented by the translation rule <-6,8>.
To find:
The correct statement for the given rule of translation.
Solution:
Rule of translation is <-6,8>.
Here, x-coordinate represents horizontal shift and y-coordinate represents vertical shift.
x-coordinate is -6, which is negative. So, the figure translated 6 units left.
y-coordinate is 8, which is positive. So, the figure translated 8 units up.
Thus, translation in words is defined as "6 units to the left and 8 units up".
Therefore, the correct option is B.
Suppose your family is taking a road trip of 120 miles to visit a family member how long would it take to make the trip if you go 40 miles per hour ?

Marian wishes to buy a new computer that will cost her $300. She receives $5 per hour for babysitting her younger brother and $4 per hour for helping her mother with chores. Each week she babysits her brother for 4 hours and helps her mother with chores for 10 hours. How many full weeks must she work to earn enough money to buy the computer?
Answer:5 weeks
Step-by-step explanation: Multiply the amount of hours and money she gets from baby sitting and chores and add the answers together. This equals 60 dollars a week. 300 divided by 60 is 5.
The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis
Answer:
P'(3,-7) Q'(7,6) R'(-8,-7).
Step-by-step explanation:
Reflection across the x-axis
Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.
We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:
P'(3,-7) Q'(7,6) R'(-8,-7).
The new triangle has vertices P'Q'R'.
I need help, please and thank you. I know that you have to multiply the diameter by 2 to find the radius, but with the 9 pi, it makes me unsure if I'm doing this correctly.
Answer:
r=6
Step-by-step explanation:
The area of a circle is given by πr². Note that this uses the radius, not the diameter.
Now, one quarter of this area (ABC) is given to be 9π.
So apparently:
[tex]\frac14 \pi r^2 = 9\pi[/tex]
If you solve this:
[tex]\frac14 r^2 = 9[/tex] (divide both sides by π)
[tex]r^2 = 9\cdot4[/tex] (multiply both sides by 4)
so
r = √36 = 6
so the radius is 6.

The mass of a rock sample is 25 g and
its density is 5 g/cm². What is the
volume of the rock sample?
Answer:
given us,
mass= 25g
density= 5 g/ cm2
here,
volume = mass/ density
= 25g/ 5g cm2
= 5cm2
Step-by-step explanation:
cm2 is the square
Answer:
5
Step-by-step explanation:
25 / 5 = 5 mass / density = volume

Widget Wonders produces widgets. They have found that the cost, c(x), of making x widgets is a quadratic function in terms of x. The company also discovered that it costs $17 to produce 2 widgets, $69 to produce 4 widgets, and $417 to produce 10 widgets. Here is the cost function used to represent this situation in terms of the number of widgets produced: c(x) = 4x2 + 2x - 3
Find the total cost of producing 6 widgets.
Answer:
the total cost of producing 6 widgets is $231

If the graph of the parent function f(x) = x is shifted 7 units down, which of the following equations would the new graphed line represent?
Answer:
Option (2)
Step-by-step explanation:
If a function g(x) is shifted 'a' units downwards then the equation of the transformed function will be,
g(x) = f(x) - a
Similarly, when the parent function is shifted 'a' units upwards, equation of the transformed function will be,
g(x) = f(x) + a
If the parent function is f(x) = x
And the graph of this function is shifted 7 units downwards,
Transformed function will be,
f'(x) = x - 7
Option (2) will be the correct option.

Answer:
x = 45°
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
since the whole angle is a right angle, we know its worth 90 degrees. since the line separates the 90 into two, with one part being 45, we can take 45 away from 90, and get our answer. 90-45=45. so the value of x=45

What is the slope of the line through (3, 2) and (-3,4)?
Answer:
Choice A. -3
Step-by-step explanation:
Using the x1-x2/ y1-y2 u fill in. So it would be 3-(-3) (x-axis) and 2-4 (y-axis).
So when u do both of those you are left with 6/-2.
When u simplify 6/-2 you get -3.
Answer:
slope is -1/3
Step-by-step explanation:
slope is read rise over run so the line, in this case, fell down 1 and ran 3. Falling means negative so the slope is negative 1 over 3. To easily determine a negative slope, see if the line is moving from top left to bottom right. If so, then it's negative. The other way around is a positive slope.

At Guevarra Clan Reunion, 4 1/2 kg of spaghetti was left.Lf there are 6 families,how much each family can take home equally.How much each family can take home equally?
Answer:
3/4 kg of sphagetti each
Step-by-step explanation:
The amount each family can take home, if the kg of sphagetti is divided equally is calculated as:
Kg of sphagetti left/Number of families
= 4 1/2kg/6
= 9/2 ÷ 6
= 9/2 × 1/6
= 9/12
= 3/4 kg
Hence, each family can take home 3/4 kg of sphagetti each.
Bok Sanctuary in Lake Wales, FL, has a carillon tower that is 205 feet tall. Heather made a scale drawing of the tower using the scale 1 inch : 20 feet. In which proportion does h represent the height, in inches, of Heather's scale drawing?
Answer:
10.25 inches
Step-by-step explanation:
Given that:
Actual height of tower = 205 feets
Ratio of scale drawing = 1 inch : 20 feets
The proportion of the height of the scale drawing will be :
Actual height / 20 feets
205 feets / 20 feets
= 10.25 inches
h in inches of the scale drawing will be 10.25 inches
