$\\ \sf\longmapsto 9x+46=35$

$\\ \sf\longmapsto 9x=35-46$

$\\ \sf\longmapsto 9x=-11$

$\\ \sf\longmapsto x=\dfrac{-11}{9}$

(X-2)²+(y-1)²=25 how do you do this problem?

Tasya [4]

$(x-x_c)^2+(y-y_c)^2=r^2\\
(x_c,y_c) - \text{center}\\\\
(x-2)^2+(y-1)^2=25\\
\text{center}=(2,1)\\
r=\sqrt{25}=5$

The height of a rocket launched upward from a 160 foot cliff is modeled by the function h(t)= -16t^2+48t+160, where h is height

aliina [53]

Answer:

5 seconds

Step-by-step explanation:

In order to find the time when it landed, we will have to find the x-intercepts.

Equation given to us : -16t² + 48t + 160

Let's take the GCD, which is -16.

-16( t² - 3t - 10 )

Factoring what's inside the brackets, we get the x-intercepts.

What multiples to -10 but adds up to -3? The numbers are -5 and 2

-16 ( t - 5 ) ( t - 2 )

X-intercepts are t - 5 and t - 2

Which is 5 and 2 seconds. But one of this is an extraneous solution and that is 2.

If we substitute the value of 2 in the equation, we will not get 0.

During the x-intercept, the x has a value and y is 0. If we substitute 5 ans x. we will get y as 0.

Hence, the answer is 5 seconds.

A researcher is interested in estimating the difference in two population proportions. A sample of 400 from each population resu

sergey [27]

Answer: (-0.086, 0.026)

Step-by-step explanation:

The confidence interval for the difference of two population proportion is given by :-

$p_1-p_2\pm\ z_{\alpha/2}\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}$

Given : Significance level : $\alpha: 1-0.90=0.10$

Critical value : $z_{\alpha/2}=1.645$

Sample size : $n_1=400,\ n_2=400$

$p_1=0.61,\ p_2=0.64$

The 90% confidence interval for the difference in the population proportions will be :-

$0.61-0.64\pm\ (1.645)\sqrt{\dfrac{0.61(1-0.61)}{400}+\dfrac{0.64(1-0.64)}{400}}\\\\\approx-0.03\pm0.056=(-0.03-0.056,-0.03+0.056)\\\\=(-0.086, 0.026)$
