PtichkaEL [24]

Answer:

Step-by-step explanation:

The formulae for simple interest is PxRxT/100 where P is the principal, R the Rate and T the time. P= 1100 R= 4.5 and T= 3. Therefore 1100×4.5×3/100=148.5. Implies the Simple Interest is $148.5

Graph the line with the slope of 3/5 and goes through the point (1,2)
olga55 [171]

Answer:

Step-by-step explanation:

First put a point at the location (1,2) on the coordinate plane. After that you need to go three points up and five right. Continue until you reach the edge of the plane. If the plane has four quadrants do the same going down, accept it will be starting at (1,2) going down 3 and left 5.

Hope this helps!!

The vertices of are D(7, 3), E(4, -3), and F(10, -3). Write a proof to prove that is isosceles.
nataly862011 [7]
<span>The vertices of are D(7, 3), E(4, -3), and F(10, -3)

Prove tat DE = DF
Length of a segment = </span>√[(x₂ - x₁) +(y₂ -y₁)]

DE = √([4-7)² + (-3 -3)²] = √45 = 3√5
DF = √[(10-7)² +(-3 -3)²] = √45 b= 3√5
Hence DE = DF = 3√5 and DEF is  ISOSCELES

What is the discriminant of the quadratic equation 2x + 5x2 = 1? –18 –16 22 24
AlexFokin [52]

Answer:

24

Step-by-step explanation:

Given a quadratic equation in standard form, ax² + bx + c = 0 (a ≠ 0 )

Then the discriminant is

b² - 4ac

Given

2x + 5x² = 1 ( subtract 1 from both sides )

5x² + 2x - 1 = 0 ← in standard form

with a = 5, b = 2, c = - 1 , then

b² - 4ac = 2² - (4 × 5 × - 1) = 4 - (- 20) = 4 + 20 = 24

1. If m∠5 = 115 degrees, find m∠1 = 115°

they form corresponding Angle pair.

2. If m∠7 = 30 degrees, find m∠2 = 30°

they form Alternate Exterior angle pair.

3. If m∠6 = 50 degrees, find m∠4 = 50°

they form Alternate interior Angle pair

4. If m∠4 = 72 degrees, find m∠1 = 180° - 72°

so, m∠1 = 108°

because, they form linear pair.
