Find the measure of the angle indicated

Grace [21]

Answer:

Step-by-step explanation:

y + 28 + 58 = 180

y + 86 = 180

y = 180 - 86

y = 94

x + y = 180

x + 94 = 180

x = 180 - 94

x = 86

A ball has been thrown into the air its distance from the ground is given by the function s(t)=-16t^2+96t+100

slega [8]

Answer:

For t=3 sec the velocity change from positive to negative

Step-by-step explanation:

we have

$s(t)=-16t^2+96t+100$

This is the equation of a vertical parabola open downward (the leading coefficient is negative)

where

s(t) is the distance in feet

t is the time in seconds

We know that

To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation

The turning point of the quadratic equation is the vertex

Convert the quadratic equation into vertex form

$s(t)=-16t^2+96t+100$

Factor -16

$s(t)=-16(t^2-6t)+100$

Complete the square

$s(t)=-16(t^2-6t+9)+100+144$

$s(t)=-16(t^2-6t+9)+244$

Rewrite as perfect squares

$s(t)=-16(t-3)^2+244$

The vertex is the point (3,244)

therefore

For t=3 sec the velocity change from positive to negative

Write the given trinomial if possible as a square of a binomial or as an expression opposite to a square of a binomial: 15ab-9a^

MrMuchimi

Answer:

$- \bigg(3a - \frac{5}{2} b) \bigg)^{2}$

Step-by-step explanation:

$15ab-9a^2-6 \frac{1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{6 \times 4 + 1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{24+ 1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{25}{4} b^2 \\ \\ = 15ab- (3a)^2- \bigg(\frac{5}{2} b \bigg)^2 \\ \\ = - \{ - 15ab + (3a)^2 + \bigg(\frac{5}{2} b \bigg)^2 \} \\ \\ = - \{ (3a)^2 + \bigg(\frac{5}{2} b \bigg)^2 - 15ab \} \\ \\ = - \bigg(3a - \frac{5}{2} b \bigg)^{2}$

What is the g.c.f of 18x15

babunello [35]

Answer:

Step-by-step explanation:

List all possible factors of each number. The GCF will be the largest number they both share

Factors of 18: 1, 2, 3, 6, 18

Factors of 15: 1, 3, 5, 15

The largest number they both share is 3, so that is the GCF
