The question is asking us to find the temperature which is 15 degrees lower than seven degrees Celsius.
The mathematical symbol used for lower than is a subtraction sign that is -.
15 lower than 7 degree = 7-15 = -8.
7 and 15 have opposite sign so will be subtracted .The answer will take the sign of the bigger number.
The temperature that is 15 degrees lower than seven degrees Celsius is -8°C
Answer:
The entire class is done in 80 minutes
Step-by-step explanation:
20 % = 20/100 = 1/5
1/5 of the class in 16 minutes
Multiply each by 5
1/5 *5 of the class in 16*5 minutes
1 of the class in 80 minutes
The entire class is done in 80 minutes
Answer:
The zeros of the given polynomial are and .
Step-by-step explanation:
Consider the given polynomial,
We have to find the zeros of the given quadratic equation,
Solving using middle term splitting method,
-11x can be written as a sum of -15x and 4x and it will given product as -60.
The equation thus can be written as,
and
Zeros satisfies the polynomial , when we put them back in the equation, it must give result as zero.
Thus, the zeros of the given polynomial are and
lim x^3 = 8.
x approaches 2

tan(Y) =
Answer:
tan∠Y = 2,14
Step-by-step explanation:
First , we need to determine XY
in order to do that we use the Pythagorean theorem :
XY = √(85^2-77^2) = 36
tan∠Y = 77/36 = 77÷36 = 2,138888888889
Answer:
Step-by-step explanation:
Triangle WXY is a right angle triangle.
From the given right angle triangle
WY represents the hypotenuse of the right angle triangle.
With ∠Y as the reference angle,
XY represents the adjacent side of the right angle triangle.
WX represents the opposite side of the right angle triangle.
To determine XY, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
85² = 77² + XY²
XY² = 85² - 77² = 7225 - 5929
XY = √1296 = 36
To determine tan Y, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan Y = 77/36
Tan Y = 2.14
