Answer: 1221
Step-by-step explanation:
Given : A 4-digit number is a palindrome .
If it has remainder 21 when you divide it by 100, then last two digits are 21.
So required palindrome = _ _ 21
since palindrome does not change if you write it backwards, so first two numbers should be reverse of 21 = 12
hence, the complete palindrome = 1221
So the number is 1221.
The equation that describes the number of bacteria in both the foods when they are mixed is; Option C: 35T₂ + 55T + 450
<h3>How to simply quadratic Equations?</h3>
We are given the equations that describes the number of bacteria in both the foods when they are mixed.
Equation for first bacteria is;
N₁(T) = 15T₂ + 60T + 300
Equation for second Bacteria is;
N₂(T) = 20T² - 5T + 150
The equation that describes the number of bacteria in both the foods when they are mixed is;
N₁(T) + N₂(T) = 15T₂ + 60T + 300 + 20T² - 5T + 150
⇒ 35T₂ + 55T + 450

Answer:
∠ VWU = 48°
Step-by-step explanation:
Since VW and VU are congruent then the triangle is isosceles with 2 base angles being congruent , that is
∠ VWU = ∠ VUW , then
∠ VWU =
=
= 48°
