Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
Answer:
A| 12, 3
Step-by-step explanation:
The polynomial can be factored by looking for factors of 36 that sum to -15. The sum being negative while the product is positive means both factors will be negative. The answer choices suggest ...
y = (x -12)(x -3)
A quick check shows this product is ...
y = x^2 -12x -3x +36 = x^2 -15x +36 . . . . as required
The factors are zero when x is either 12 or 3.
The zeros of the equation are 12 and 3.
____
Once you realize the constants in the binomial factors both have a negative sign, you can immediately choose the correct answer (A).
Or, you can use Descartes' rule of signs, which tells you that the two sign changes in the coefficients (+-+) mean there are 2 positive real roots.
Answer:
4
Step-by-step explanation:
The answer to this is -76
Using the given endpoint R (8,0)and the midpoint M (4,-5) , the other endpoint S is (0,-10)
Explanation :
Use the given endpoint R and the midpoint M of segment RS
R (8, 0 ) and M (4, -5 )
Let 'S' be (x2,y2)
Apply the midpoint formula
Endpoint R is (x1,y1) that is (8,0)
Substitute the values and make it equal to M(4,-5)
So other endpoint S is (0,-10)
