determine the y-intercept
Answer:
-21
Step-by-step explanation:
the y intercept is when x=0.
you can see that this is a linear equation where each increase in x results in an increase of 4 onto the y value.
so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.
-17 -4=-21

1,000 = 58.3x+227.9
Answer:
x=13.243568
Step-by-step explanation:
1000=58.3x+227.9
Step 1: Flip the equation.
58.3x+227.9=1000
Step 2: Subtract 227.9 from both sides.
58.3x+227.9=1000
−227.9 −227.9
58.3x=772.1
Step 3: Divide both sides by 58.3
58.3x/58.3 = 772.1/58.3
x=13.243568

Question:
Solve for x
(x+3)^2
Answers:
2x^2 + 3x + 2
x^2 + 6x + 9
Answer:
x² + 6x + 9
Step-by-step explanation:
(x + 3)² = (x + 3)(x + 3)
Each term in the second factor is multiplied by each term in the first factor , that is
x(x + 3) + 3(x + 3) ← distribute parenthesis
= x² + 3x + 3x + 9 ← collect like terms
= x² + 6x + 9
Represent the area of the region determined by the intersection of the circles x
2 + y
2 = 4
and (x − 2)2 + (y − 2)2 = 4 by an integral. Do not evaluate the integral.
I think you mean the circles
x² + y² = 4
(x - 2)² + (y - 2)² = 4
Notice that both have radius 2, but the first one is centered at the origin (0, 0) while the second one is centered at (2, 2). The two circles intersect at the points (2, 0) and (0, 2), which means the bounded region between them is contained entirely in the first quadrant.
If we solve both equations above for y, we would find two solutions in each case:
x² + y² = 4 ⇒ y = ± √(4 - x²)
(x - 2)² + (y - 2)² = 4 ⇒ y = 2 ± √(4 - (x - 2)²)
The positive/negative root corresponds to the upper/lower semicircle the make up the full circle. The semicircles we're interested in are
y = + √(4 - x²)
y = 2 - √(4 - (x - 2)²)
that is, the upper half of the circle centered at the origin, and the lower half of the circle centered at (2, 2).
So, in standard Cartesian coordinates, the bounded region (call it R) is the set
[tex]R = \left\{(x, y) : 0 \le x \le 2 \text{ and } 2-\sqrt{4-(x-2)^2} \le y \le \sqrt{4-x^2} \right\}[/tex]
and the area is given by the double integral
[tex]\displaystyle \iint_R dA = \boxed{\int_0^2 \int_{2-\sqrt{4-(x-2)^2}}^{\sqrt{4-x^2}} dy \, dx}[/tex]

The expected number of female children in a family with three children is 1.5.
The correct option is B.
We have to determine
What is the expected number of female children in a family with three children?
Probability;Probability is defined as the sum of all observations and the number of observations.
The expected value of female children= Probability of female children x Total number of children.
A child can be male or female, so there are 2 combinations, the favorable outcome is female.
The probability of female children = 1/2.
Therefore,
The expected number of female children in a family with three children is;
[tex]= \dfrac{1}{2}\times 3\\\\=1.5[/tex]
Hence, The expected number of female children in a family with three children is 1.5.

She should not have included an equal sign. She should have used parentheses to show that Negative 2 is multiplied by (x minus 4. 5). She should have subtracted the difference (x minus 4. 5) from Negative 2. She should have used parentheses to show that Negative 2 is multiplied by (4. 5 minus x).

The price of a new car is $30,000. If the sales tax is 6.5%, what is the total cost for the car, including tax?
Answer:
$31950
Step-by-step explanation:
We multiply 30,000 by .065 to get 1950. We ad them together to get $31,950. :)
Answer:
$31,950 dollars
Step-by-step explanation:
Given the following question:
Initial price of the car is $30,000...
The car has an increase tax of 6.5% (which means 6.5% of the initial price of the car is the sales tax.)
In order to find the total cost of the car, we need to find 6.5% of $30,000 and then add that number to the initial price to have the answer.
[tex]\frac{6.5\times30000}{100} =6.5\times30000=19500\div100=1950[/tex]
[tex]30000+1950=31950[/tex]
[tex]t=31950[/tex]
Therefore, the car has the total cost (including tax) of "$31,950 dollars."

A cannonball is released at an angle of 20˚ at a velocity of 12m/s. Calculate the horizontal velocity of the object. What kinematic formula must be used to solve this problem?.
The horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.
What is Velocity?Velocity is the rate of change of position with respect to time. It is a scalar quantity.
We know that the velocity is a scalar quantity therefore, it can be divided into two components such that the first component is the vertical component which is equal to the (V sinθ), while the other component is the horizontal component(V cosθ), where V is the velocity and θ is the angle of the velocity from the positive x-axis.
Now, in order to calculate the horizontal velocity of the cannonball we can write,
[tex]\rm V_x = V\ Cos\theta[/tex]
[tex]V_x = 12 (Cos\ 20^o)\\\\V_x = 11.276\rm\ m/s[/tex]
Hence, the horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.

Use the bar graph. Astronauts installed 15 new tiles on the outside of the space station they spent 390 minutes on the task. each tile took the same amount of time to install. draw a bar in the graph to show the time needed to install a tile. Explain
Answer:
11. It will take about 26 minutes to install a singular tile.
12. It will take about 10 more minutes to install a light than it does to install a cable.
Step-by-step explanation:
11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.
390/15= 26 minutes
It will take about 26 minutes to install a single tile.
12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.
22-12= 10 minutes
It takes about 10 minutes longer to install a light than it does a cable.
It took about 26 minutes to install a single tile and 10 minutes longer to install a light than it does a cable.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given,
Installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time,
We have to divide the total amount of time by the number of tiles.
390/15= 26 minutes
It will take about 26 minutes to install a single tile.
By observing the chart, it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.
22-12= 10 minutes
