Evaluate 7 + (-3x^2) for x = 0. 4

Mathematics
1 answer:
Goshia [24]3 years ago
6 0

Step-by-step explanation:

By substituting x = 0.4 in equation 7 + (-3x^2)

= 7 - 3 (0.4)^2

First solving o.4^2 as per the rule of BODMAS

= 7- 3 (0.16)

Now multiplying -3 with 0.16

= 7 - 0.48

= 6.52 THIS IS THE ANSWER

A quadrilateral has exactly one right angle and two nonadjacent angles that each measure 105 degrees
LiRa [457]

Answer:

C) Kite

Step-by-step explanation:

The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.

Therefore, the answer is C) Kite

Hope this helps!

Find the scale factor from DEF to ABC
Serjik [45]

Answer:

³/2 (1.5)

Step-by-step explanation:

∆DEF was enlarged to get ∆ABC. The scale factor would be:

The ratio of any of the side length of ∆ABC to the corresponding side length of ∆DEF.

Thus,

BC:EF = 12:8

= 12/8

= 3/2 = 1.5

Scale factor from ∆DEF to ∆ABC is ³/2 or 1.5
