liraira [26]

Answer:

6b < 24

⇔ b < 24/6

⇔ b < 4

4b + 12 > 4

⇔ 4b > 4 - 12

⇔ 4b > -8

⇔ b > -8/4

⇔ b > -2

The number T of teams that have participated in a robot-building competition for high-school students over a recent period of ti

Katarina [22]

Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.

The number of teams after x years is given by:

$T(x) = 17.155x^2 + 193.68x + 235.81$

Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:

$17.155x^2 + 193.68x + 235.81 = 1000$

$17.155x^2 + 193.68x - 764.19 = 0$

Which has coefficients $a = 17.155, b = 193.68, c = -764.19$ , then:

$\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66$

$x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1$

$x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3$

We want the positive root, so the number of teams is greater than 1000 after 3.1 years.

the height of the triangle is 4cm and the base width is 18 cm and the base length is 18 cm what is the surface area of a square

Gnesinka [82]

Answer:

The surface area is 664 cm²

Step-by-step explanation:

$A=a^{2} +2a\sqrt{\frac{a^{2}}{4} } +h^{2}$ Use this equation to find the surface area

$A=18^{2} +2(18)\sqrt{\frac{18^{2}}{4} } +4^{2}$ Simplify

$A=324 +36\sqrt{\frac{324}{4} } +16$ Simplify

A = 324 + 36√81 + 16 Simplify

A = 324 + 36(9) + 16 Simplify

A = 324 + 324 + 16 Simplify

A = 664 cm²
