D equals 38.2 I think because t equals 9.55. You would add -16t with -4t and get -20t. Which would turn into D=-20t^2+382. Since you can't multiply 2 with -20t, you would divide it by 382 which would be 191. D=-20t+191 with this, you would subtract 191 from +191 which would cancel out and it would turn the problem into -191=-20t. You would divide -20 from itself and -191 and get t=9.55. Then you plug t where it was in the problem and then you get that D=38.2. I hope my answer is right and it helps you.
In an isosceles triangle, two of the angles are equal. And, a triangle’s three angles add up to 180.
So: if an isosceles triangle has one angle measuring 38 degrees, it also has another angle measuring 38 degrees. To find the measure of the third angle, subtract from 180 the sum of the two other angles. Like this: 180 - (38+38). Then solve it: 180 - 76 = 104.
So: the angles are 38 degrees, 38 degrees, and 104 degrees.
Answer:
0.7
Step-by-step explanation:
To get 7/10 as a decimal you simply divide 7 by 10 which gets you 0.7.
Answer:
Yes since the triangles are congruent by ASA. See proofs and explanation below.
Step-by-step explanation:
The cardio and free weights will have the same amount of space because triangles ABE and BCE are congruent by ASA or Angle-Side-Angle. We know that angle AEB and angle DEC are congruent since they are vertical angles. This is the first angle is ASA. We also know that the two triangles must be congruent because line segment DE is congruent to line segment EB since E is the midpoint of DB. This is the side in ASA. Lastly, the other angle of ASA can be proven because AB and DC are parallel lines. SInce they are parallel they have special angle relationships when the transversal DB intersects them. Since angle ABE and angle EDC are alternate interior angles, they are congruent. This means the triangles must be congruent. When triangles are congruent, then each triangle is the same shape and size. This means their area is the same too. Therefore, cardio and free weights have the same amount of space.
To write a two columns proof, start with given information, add new information, and then conclude.

Respuesta:
Por lo tanto, los valores de y correspondientes son 3, 2, 4 y 8
Explicación paso a paso:
Dada la función f (x) = -5x + 3
Cuando x = 0
f (0) = -5 (0) + 3
f (0) = 0 + 3
f (0) = 3
Cuando x = 1/5
f (1/5) = -5 (1/5) + 3
f (1/5) = -1 + 3
f (1/5) = 2
Cuando x = -1/5
f (-1/5) = -5 (-1/5) + 3
f (-1/5) = 1 + 3
f (-1/5) = 4
Cuando x = -1
f (-1) = -5 (-1) + 3
f (-1) = 5 + 3
f (-1) = 8
