Answer:

26 units

Step-by-step explanation:

Pythagoras' Theorem: \sf a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given

  • a = 10
  • b = 24

Substitute the given values into the formula and solve for c:

\sf \implies 10^2+24^2=c^2

\sf \implies c^2=676

\sf \implies c=\pm\sqrt{676}

\sf \implies c=\pm26

Since length is <u>positive</u>, c = 26 only

Answer:

26 units

Step-by-step explanation:

To find the missing side length, we need to use <u>Pythagoras theorem</u>, as this triangle is a <u>right triangle.</u>

Formula: h² = x² + y²                                       [h = hypotenuse, x and y = legs]

Legs: 10 units and 24 units                                              (Stated in comments)

Finding the third side of the triangle (h):

⇒ h² = 10² + 24²

<u>Simplify the LHS:</u>

⇒ h² = 100 + 576

⇒ h² = 676

<u>Take a square root both sides:</u>

⇒ √h² = √676

⇒ h = ±26

⇒ h = 26                                                 (Side lengths can <u>never</u> be negative)

Thus, the length of the third side is 26 units.

Factor the expression completely over the complex numbers.<br><br> y^4+12y^2+36
Brums [2.3K]
Y⁴ + 12y² + 36
Now factorize the expression
y⁴ + 6y² + 6y² + 36
= y²(y² + 6) + 6(y² + 6)
= (y² + 6) (y² + 6)
<span>Now 6 is not the perfect square and according to rule, binomial can not be factored as the difference of two perfect squares.
</span>so multiply both.
(y² + 6)² is the answer.

The temperature, T, for an oven can be described by the equation T = 44m +67 for the
My name is Ann [436]

Answer:

T-intercept = 67

Step-by-step explanation:

Given

T = 44m + 67

Required

Calculate and interpret the t-intercept

To calculate the t-intercept, we simply set the number of minutes (m) to 0

i.e. substitute 0 for m in T = 44m + 67

T = 44 * 0 + 67

T = 0 + 67

T = 67

Hence, the T-intercept is 67

The interpretation is that the initial temperature when the oven is turned on is 67 degrees
