The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

Correctly multiply (3x + 7) (7x + 5)
Then find the sum of the coefficients of your solution.
Answer:
The sum of the coefficients is 85.
Step-by-step explanation:
(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x
7 * 7x is 49x
7 * 5 is 35
21x^2 + 15x + 49x + 35
So the answer is 21x^2 + 64x + 35
Add the coefficients: 21 + 64 = 85
The scatterplot illustrates the relationship between two quantitative variables: the number of seeds planted per square foot and the yield of the crop (in pounds per square foot).
A graph titled Number of Seeds and Crop Yield has seeds (per square foot) on the x-axis, and yard (pounds per square foot) on the y-axis. The points curve up to a point, and then curve back down.
Which of the following is an accurate description of the scatterplot?
Answer:
I cannot confirm answer (D), but it looks correct to me.
Here's the option:
The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square foot is around 60.

1. A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 64t + 400. (solve step by step pls)
2. In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
The interval for the given situation is (0, 4).
Given that, height = 400 ft, initial velocity of 64 ft/s and the equation s(t) = -16t² + 64t + 400.
What is an initial velocity?Initial velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
To find the interval in which the ball is higher than the building, solve the inequality h(t) > 400. The inequality is easily solved by subtracting 400 so the comparison is to zero, factoring the expression involving t, and identifying the time interval in which the signs of the factors are the same.
-16t² +64t +400 > 400
⇒ -16t² +64t > 0
⇒ -16t (t -4) > 0
⇒ t=0 and t-4=0
Both factors will have negative signs on the interval (0, 4).
Therefore, the interval for the given situation is (0, 4).

Step-by-step explanation:
If you divide 14 by 0 it will be 0, and you subtract by 5 it will still be 0.
Candice wrote the four equations below. She examined them, without solving them, to determine which equation has an infinite number of solutions.
Negative 5 x + 1 = negative 5 x + 1. Negative 2 x + 1 = negative 2 x + 2. 3 x + 5 = 3 x minus 5. 4 x minus 2 = x + 1.
Which of Candice’s equations has an infinite number of solutions?
Negative 5 x + 1 = negative 5 x + 1
Negative 2 x + 1 = negative 2 x + 2
3 x + 5 = 3 x minus 5
4 x minus 2 = x + 1

how to tell if a graph is a function?
Answer:
If you take a vertical line and place it on the graph, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once. If so, then it is a vertical line.
If not, then it isn't one.

− 14 n + q = r t − 4 n , for n
Answer:
n = q/10 - (r t)/10
Step-by-step explanation:
Solve for n:
q - 14 n = r t - 4 n
Subtract q - 4 n from both sides:
-10 n = r t - q
Divide both sides by -10:
Answer: n = q/10 - (r t)/10
the sides of a triangle are 5:8:10 and it's perimeter is 23 cm. find the area of triangle.
Answer:
19.81cm^2
Step-by-step explanation:
To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:
sqrt(p*(p-a)*(p-b)*(p-c))
Plugging the values into this formula gives 19.81cm^2.

the image is what your graph will look like, but with 2 lines instead of one. on the bottom, mark the months. on the side, write temperatures. Then on each month for the line for A, dot the temperature it is with a connected line. (Like the line is on the image.) Then do the same for the line for city B. I'd recommend doing it in 2 different colors, and label some where else which city.
